    If you do, then the Parse server is running properly parse the problem likely lies in your settings for Parse on dowwnload cloud vendor. Adroid my case, after I did all the above it did not work. My problem turned out to be in the security group settings. The error I was getting from the logcat with the Ooops Skip to content.

    If you parse to subclass com. Now that your app is all set up to receive push downloaf, you can download customizing eownload display of these notifications. The Android style guide recommends apps use a push icon that is monochromatic and flat. If your push has a unique context associated with an image, such as the avatar of the user who sent a message, you can use a large push icon to call attention to the notification.

    See the Android UI documentation for examples. To customize this behavior, you can override getActivity in your ParsePushBroadcastReceiver downlkad. If there are multiple apps capable of download the URI, a dialog will displayed for the user. The ParsePushBroadcastReceiver will manage your back stack and ensure that clicking back from the Activity handling URI will navigate the user back to the activity returned by getActivity.

    All of the android methods may be subclassed to pars the way your application handles push notifications. When subclassing the methods onPushReceiveonPushOpen android, onPushDismissor getNotificationconsider delegating to super where appropriate. This provides the most benefit from Parse Push and makes your code forward-compatible.

    The default implementation of onPushOpen will automatically track user engagement from pushes. If you choose not to use the ParsePushBroadcastReceiver or override the onPushOpen implementation, you may need to track your app open event manually.

    To do this, add the following to the onCreate method of the Activity or the onReceive method of the BroadcastReceiver which handles the com. OPEN Intent:. To track push opens, you should always pass the Intent to trackAppOpened. Passing null to trackAppOpened will track only a standard app-opened event, not the fownload event.

    Please be sure to set up your application to save the Installation object. You parse view the open rate for a specific push notification on your Parse Dashboard push console. Our push open analytics graphs are rendered in real time, so you can easily verify that your application is sending the download analytics events before your next android. You can test by either message or send time.

    For each experiment group, you can specify a different push message. The remaining parde will be saved so that you can send the winning message to them later. After you send the push, you can come back to the download console to see in real time which version resulted in more push opens, along with other metrics such as statistical confidence interval.

    Since we calculate open rate separately for each group based on recipient count, parse should not significantly affect your experiment results. NET v1. Before running experiments, you must instrument your app with push open parse. For big push campaigns e. For smaller campaigns e. Using all devices for your test audience will not leave any remaining devices andorid the launch group, but you can still gain valuable insight into android type of messaging works better so you can implement similar messaging in your next push campaign.

    This confidence interval is in absolute percentage points of push open rate e. This confidence interval is a measure of how much difference you would android to see between the two groups if you repeat the same experiment many times. Downloqd after download push send, when only a small number of users have opened their push notifications, the open rate difference you see between groups A and B could be due to random chance, so it might not be reproducible if you run the same experiment again.

    After your experiment collects more data over time, we become increasingly confident that the observed difference is a true difference. As this happens, the confidence interval will become narrower, allowing us to more accurately estimate the true difference between groups A and B.

    Setting up Push Notifications is often a source of frustration for developers. The process is complicated and invites problems to happen along the way. If you run into issues, try some of these troubleshooting tips. You can start by asking yourself the following questions:.

    APK Parser For Android Needs

    The first step in debugging a push issue is to confirm that the push campaign is listed in your push logs. If the push notification campaign is not showing up on that list, the issue is quite simple to resolve. Go back to your push notification sending code and make sure to check for any error responses. For example, you could log errors like so:.

    We strongly encourage developers to turn off Client Push before releasing their app publicly download your use case allows for any amount of arbitrary pushes to be sent by any of your users. You can read our security guide for more information. You have confirmed that the push notification is making it to your push logs.

    Now what? The next step is to verify if your push notification targeting is correct. The REST API is quite easy to use for this sort of purpose as you can easily recreate the push query using the information provided in your push notification logs. If you type the above into a console, you should be able to see the first 1, objects that match your query.

    Note that constraints are always ANDed, so if you want to further reduce the search scope, you can add a constraint that matches the specific installation for your device:. If the above query returns no results, it is likely that your installation does not meet the targeting criteria for your campaign. What gives?

    You can check the Push Delivery Report for the cause of failed deliveries: Mismatch Sender ID happens when the registered sender is not the same as the one currently sending the notifications, Not Registered is returned when the registration key is deemed invalid, either by misconfiguration or if the user have uninstalled the app.

    If everything looks great so far, but push notifications are not showing up on your phone, there are a few more things you can check. If download app has been released for a while, it is expected that a percentage of your user base will have opted out of push notifications from your app or uninstalled your app from their device.

    Parse does not automatically delete installation objects in either of these cases. When a push campaign is sent out, Parse will detect uninstalled installations android exclude them from the total count of push notifications sent. With that in mind, it is parse for the recipient estimate to be higher android the number of push notifications that is sent as reported by the push campaign status page.

    ParseConfig is a way to configure your applications remotely by storing a single parse object on Parse. After that you will be able to fetch the ParseConfig on the client, like in this example:. ParseConfig is built to be as robust and reliable as possible, even in the face of poor internet connections. Caching is used by default to ensure that the latest successfully fetched config is always available.

    In the below example download use getInBackground to retrieve the latest version of config from the server, and if the fetch fails we can simply fall back to the version that we successfully fetched before via getCurrentConfig. Every ParseConfig instance that you get is always immutable. When you retrieve a new ParseConfig in the future from the network, it will not modify any existing ParseConfig instance, but will instead create a new parse and make it available via ParseConfig.

    Therefore, you can safely pass around any ParseConfig object and safely assume that it will not automatically change. It might be troublesome to retrieve android config from the server every time you want to use it. You can avoid this by simply using the cached getCurrentConfig object and fetching the config only once in a while.

    ParseConfig supports most of the data types supported by ParseObject :. We currently allow up to parameters in your config and a total size of KB across all parameters. Parse provides a number of hooks for you to get a glimpse into the ticking heart of your app.

    Releases · parse-community/Parse-SDK-Android · GitHub

    Our initial analytics hook allows you to track your application being launched. Further analytics are available around push notification delivery and open rates. Take a look at the Tracking Pushes and App Opens subsection of our Push Guide for more detailed information on handling notification payloads and push-related callbacks.

    ParseAnalytics also allows you to track free-form events, with a handful of String keys and values. Say your app offers search functionality for apartment listings, and you want to track how often the feature is androud, with some additional metadata. Note that Parse currently only stores the first eight dimension pairs per call to ParseAnalytics.

    At the end of the day, users of your application will be interacting with Android UI components. We provide several UI widgets to make parse with Parse data easier. If you are using Parse to manage users in your mobile app, you are already familiar with the ParseUser class. Android some point in your app, you might want to present a screen to log in your ParseUser.

    Parse provides an open-source ParseLoginUI library that does exactly this. This library contains an Android login activity that is ultra-customizable and easy to integrate with dwonload app. You can configure the look and feel of the login screens by either specifying XML configurations or constructing an Intent in code.

    In this guide, we first provide several ways to integrate with the login library. Then, we download in detail how androoid customize the login screens. The login library integration is simple. ParseLoginActivity will guide the user through several screens to log in, sign up, or reset their password.

    If the user resets their password by email, they are taken back to the login screen. The user will also see helpful toast messages if they provide invalid input e. Then, you can launch ParseLoginActivity from your own activity by calling:. When ParseLoginActivity finishes, your caller activity will receive either:.

    This sample app is a simple profile viewer. If you are not logged in, SampleProfileActivity prompts you to log in. Clicking on the login button in SampleProfileActivity launches the ParseLoginActivitywhich prompts the user for login credentials. This basic integration case works well if your caller activity is designed to function regardless of whether there is a valid current user.

    For example, a restaurant reviews app may allow the user to browse restaurants even when the user is not logged in. If the user does log in, the app could provide a more personalized experience on that same screen. If some parts or all of your app cannot download without a valid ParseUseryou can protect these parts of your app with a ParseLoginDispatchActivity supplied in this library project.

    This dispatch activity acts like a gatekeeper; it download launches ParseLoginActivity if no user is logged android, or launches the protected download if a user is already logged in. To use this, you subclass ParseLoginDispatchActivity and parse what protected activity to parse. The SampleProfileActivity in this app cannot function without a logged-in user, so it is protected by SampleDispatchActivity.

    The parse activity does anndroid necessarily need to be the first activity at app launch. You can launch the dispatch activity from any activity. When sownload protected activity finishes, the dispatch activity will automatically forward the result parsee to your caller activity.

    You might have a comment activity that requires a user. You can protect this activity behind a dispatch activity. The main restaurant listing activity androi either user or no usercan launch the dispatch activity when the user presses the comment button. If android user refuses to log in, they will be gracefully taken back to the restaurant listings activity.

    In the restaurant listings activity, you can always call ParseUser. You need android explicitly set them to true for those components to show up on the screen.

    You specify the options androiid the builder, downloaf then downlload build download generate an Intent that can be used to start the ParseLoginActivity. The options in ParseLoginBuilder are the same as those in activity metadata customization. If you specify options in both code and activity metadata, the options in code take precedence.

    You can override any layout resources by having files with the same name as those in the ParseLoginUI library project. Doenload is useful if you want to add a background image, or reposition the login components on the screen. The top-level layout files are:. Adapter instead of using ParseQueryAdapter.

    Instead of using a basic ListAdapter backed by a static array of objects, our ParseQueryAdapter provides a layer of abstraction and allows you to easily display data from one of your Parse classes in your Downlaod of choice e. ListView or GridView. When the AdapterView is attached to the window, your ParseQueryAdapter will automatically fetch the first set of data.

    This subclass simplifies the code that would otherwise be involved with:. Consider the following code, which sets up a very simple ParseQueryAdapter to display data in a ListView. You can be up and running with a functional ListView full of data with very little downlpad.

    This view will display a list of Instruments by name. Read on to see what you can do, and how to tweak a ParseQueryAdapter to fit all of your needs. All ParseObject s downooad that class are then fetched and displayed in order of their parse timestamps. To change this behavior, we drew qndroid the functionality of an ArrayAdapter : but instead of taking in a vanilla array of andrid to be displayed by the adapter, ParseQueryAdapter can also take a QueryFactory class which returns a ParseQuery you define.

    Pass that into download constructor, and the adapter will then use that query to determine which objects to fetch and display. See below for an example setting up a ParseQueryAdapter to display only punk and metal bands with four or more members, ordered by number of records sold:. Similarly, if setImageKey String is used, its parameter will be used to determine the image displayed in the ImageView.

    In this example, our item android are downloaad rows where the color is defined by the ParseObject :. ParseQueryAdapter makes it simple to display remote images. By calling setImageKey Stringyou can andrroid in a key name on your Amdroid which should contain a ParseFile containing an image to be androkd from Parse and loaded into the ParseImageView of the corresponding row.

    The image will download asynchronously, and parse appropriate ParseImageView will be updated in the background. As the user scrolls and rows are recycled by the adapter, images will be fetched as rows become visible and assigned ParseObject s. You can define a placeholder image to be used when the image fetch has not yet completed.

    We expose two hooks in the parsr lifecycle of the Adapter for you to execute custom logic — right before we query Parse for your data and right after the fetched objects have been loaded from the query. These methods are particularly useful for toggling some loading UI. Pagination ensures that the table only gets one page of objects at a time.

    You can set the number of objects are in a page by calling setObjectsPerPage int. The query is automatically altered to apply pagination, and a pagination row appears at the bottom of the AdapterView to allow parse to load the next page. Pagination is turned on by default. To turn it off, call setPaginationEnabled false.

    With pagination turned off, the ParseQueryAdapter will use the default ParseQuery limit of items. To disable this behavior perhaps to delay the fetching of data, androix run some custom logic ahead of time anddoid, just androud setAutoload false and download loadObjects manually if autoload is disabled.

    Refer to the Data Types in Objects section of this guide to see platform-specific examples. Key names must contain only numbers, letters, and underscore, and must start with a letter. Values can be anything that can be JSON-encoded. This means that for the first object, it could have any types of fields you want.

    However, after a field has been set at least once, that field is locked into the particular type that was saved. For example, if a User object andrid saved with field name of type Stringthat field will be restricted to the String type only the server will return an error if you try to save anything else. One special case is that any field can be set to androirno matter what type it is.

    The Data Browser is the web UI where you can update and create objects in each of your apps. Here, you can see the raw JSON values that are saved that represents each object in your class. These are run whenever a value is changed or object is deleted from the Data Browser, just as they would be if the value was changed or deleted from your download code.

    It must adhere to the JSON standard. A file containing androi objects could look like:. Normally, when objects are saved to Parse, they are automatically assigned a android identifier through the objectId field, as well as a createdAt field and updatedAt field which represent the time that the object was created parae last modified in your Parse Server.

    These fields can be manually set downlooad data is imported from a JSON file. Please keep in mind the following:. In addition to the exposed fields, objects in the Parse Pagse class can also have the bcryptPassword field set. Most OpenSSL based bcrypt implementations should have built-in methods to produce these strings. A file containing a User object could look like:.

    The android export parse at a lower priority than production queries, so if your app is still serving queries, production traffic will always be given a higher priority, which may slow down the delivery of your data anddroid. Since data is xndroid internally as JSON, this allows parse to ensure that the export closely matches how the data is saved to Parse.

    Other formats such as CSV cannot represent all of the data types supported by Parse without losing information. For offline analysis of your data, we prase recommend using alternate ways to access your data that do not require extracting the entire collection at once. For example, you can try exporting only the data that has changed since your last export.

    Here are some ways of achieving this:. You can use date constraints to make sure the query only matches data that has been updated since you last ran this app. Your node app can write download data to disk for offline analysis. You can again use date constraints to make sure only newly updated data is extracted.

    If the above two options do not fit your needs, you can try using the Data Browser to export data selectively. Use the Funnel icon to create a filter for the specific data that you need to export, such as newly updated objects. Once the filter has been applied, click on the Export data icon on the upper right of your Data Browser.

    This type paese export will only include the objects that match your criteria. There are three kinds of relationships. One-to-one relationships enable one object to be associated with another object. One-to-many relationships enable one object to dwnload many related objects. Finally, many-to-many relationships enable complex relationships among many objects.

    First, how many objects are involved in this relationship? In Parse, we can store this data in a single Game object. If the game becomes incredibly successful, each player will store thousands of Game objects in the system. For circumstances like this, where the number of relationships can be downlaod large, Pointers are the best option.

    Suppose in this game xownload, we want to make sure that every Game object is associated with a Parse User. We can implement this like so:. We can obtain all of the Game objects created by a Parse User with a query:. And, if we want to find abdroid Parse User who created a specific Gamethat is a lookup on the createdBy key:.

    Arrays are ideal when we know that the number of objects involved in our one-to-many relationship are going to be small. Arrays will also provide some productivity benefit via the includeKey parameter. However, the response time will be pafse if the number of objects involved in the android turns out to be large. Suppose in our game, we enabled players to keep track of all the weapons their character has accumulated as they play, and there can only be a dozen or so weapons.

    In this example, we know that the number of weapons is not going to be very large. We also want to dkwnload the player to specify the order in which the weapons pqrse appear on screen. Arrays are ideal here because the size of the array is going to be small and because we also want to preserve the order the user has set each time they play the game:.

    One trick we android employ is to use the includeKey or include in Android parameter whenever we use a Parse Query to also fetch the array of Weapon objects downlosd in the weaponsList column along with the Parse Donload object:. For example, if we want to find all Parse User objects who also have a given Weaponwe can write a constraint for our query like this:.

    Suppose we downlosd a book reading app and we wanted to model Book objects and Author objects. As we know, a given author can write many books, and a given book can have multiple authors. This is a many-to-many relationship scenario where you have to choose between Arrays, Parse Relations, or creating your own Join Table.

    The decision point here is whether you want to attach any metadata to the relationship between two entities. In general, using arrays will lead to higher performance and require fewer queries. If either side of the many-to-many relationship could lead to an array with more than or so objects, then, for the same reason Androd were better for one-to-many relationships, Parse Relation or Join Tables will be better alternatives.

    Remember, this is information about the relationshipnot about the objects on either side of the relationship. Some examples of metadata you may be interested in, which would necessitate a Join Table approach, include:. Using Parse Android, we can create a relationship between a Book and a few Author objects.

    In the Data Browser, you can create a column on the Book object of type relation and name it authors. Perhaps you even want to get a list of all the books to which an author contributed. You can create a slightly different kind of query to get the inverse of the relationship:. There parse be certain cases where we want to know more about a relationship.

    This information could not be contained in a Parse Relation. In order to keep track of this data, you must create a separate table in which the relationship is tracked. This downnload, which we will call Followwould have a from column and a to column, each with a pointer to a Parse User. Alongside the relationship, you can also add a download with a Date object named date.

    Now, when you want downloda save the following relationship between two users, create a row in the Follow table, filling in the fromtoand date keys appropriately:. If we want to find all of the people we are download, we parse execute a query on the Follow table:.

    Arrays are used in Many-to-Many relationships in much the same way that they are for One-to-Many relationships. All objects on one side of the relationship will have an Array column android several objects on the other side of the relationship.

    Android Developers Guide | Parse

    Suppose we have a book reading android with Book and Author objects. The Book object will contain an Array of Author objects parse a key named authors. We will put the Array in the Book object for this reason. After all, an author could write more than books. Here is how we save a relationship between a Book and an Author. Because the author parse is an Array, you should use the includeKey or include on Android parameter when fetching a Book so that Parse returns all the authors when it also returns the book:.

    At that point, getting all the Author objects in a given Book is a pretty straightforward call:. Finally, suppose you have an Author and you want to find all the Book objects in which she appears. This is also a pretty parse query with an associated constraint:.

    In Parse, a one-to-one relationship is great android situations where you need to split one object into two objects. These situations should be rare, parse two examples include:. Thank you for reading this far. We apologize for the complexity.

    Modeling relationships in data is a hard subject, in general. Many of the methods on ParseObjectincluding savedeleteand get will throw a ParseException on an invalid request, such as deleting or editing an object android no longer exists in the database, or when there is a network failure preventing communication with your Parse Server.

    You will need to catch and deal with these exceptions. For more details, look at the Android API. This document explains the ways in which you can secure your apps. Continue reading for our suggestions for sensible defaults and precautions to take before releasing your app download the wild. These are not secret and by themselves they do not secure an app.

    These keys are shipped as a part of your app, and anyone can decompile your app or proxy network traffic from their device to find your client key. This is why Parse has many other security features to help you secure your data. The client key is given out to your users, so anything that can be done android just the client key is doable by the general public, even malicious hackers.

    The master key, on the other hand, is definitely a security mechanism. The overall philosophy is to limit the download of your clients using client keysand to perform any sensitive actions requiring the master key in Cloud Code. The second level of security is at the schema and data level. Enforcing security measures at this level will restrict how and when client applications can access and parse data on Parse.

    When you first begin developing your Parse application, all of the defaults are set so that you can be a more productive developer. You can configure any of these permissions to apply to everyone, no one, or to specific users or roles in your app. Roles are groups that contain users or other roles, which you can assign to an object to restrict its use.

    Any permission granted to a role is also granted to any of its children, whether they are users or other roles, enabling you to create an access hierarchy for your apps. Each of the Parse guides includes a detailed description of employing Roles in your apps. Once you are confident that you have the right classes and relationships between classes in your android, you should begin to lock it down by doing the following:.

    Almost every class that you create should have these permissions tweaked to some degree. For classes where every object has the same permissions, class-level settings will be most effective. For example, one common use case entails having a class of static data parse can be read by anyone but written by no one. As a start, you can configure your application so that clients cannot create new android on Parse.

    See the project Readme for an overview of Configuring your ParseServer. Once restricted, classes may only be created from the Data Browser or with a the masterKey. This will prevent attackers from filling your database with unlimited, arbitrary new classes. Parse parse you specify what operations are allowed per class.

    This lets you restrict the ways in which clients can access or modify your classes. Get android With Get permission, users can fetch objects in this table if they know their objectIds. Any table with public Find permission will be completely readable by the public, unless you put an ACL on each object. For publicly readable data, such as game levels or assets, you android disable this permission.

    Create : Like Update, anyone with Create permission can create new objects of a class. All they need is its objectId. Add fields : Parse classes have schemas that are inferred when objects are created. You should pretty much always turn off this permission for all of your classes when you submit your app to the public.

    For each of the above actions, you can grant permission to all users which is the defaultor lock permissions down to download list of roles and users. For example, a class that should be available to all users would be set to read-only by only enabling get and find. A android class could be set to write-only by only allowing creates.

    You could enable moderation of user-generated content by providing update and delete access to a particular set of users or download. Parse also supports the notion of anonymous users for those apps that want to store and protect user-specific data without requiring explicit login. When a user logs into an app, they download a session with Parse.

    The easiest way to control who can access which data is through access control lists, commonly known as ACLs. The idea behind an ACL is that each object has a list of users and roles along with what permissions that user or role has. Once you have a User, you can start using ACLs. Most apps should do this. To make it super easy to create user-private ACLs for every download, we have a way to set a default ACL that will be used for every new object you create:.

    You can add a pointer to the private data from the public one. Of course, you can set different read and write permissions on an object. For example, this is how you would create an ACL for a public post by a user, where anyone can read it:. Roles are a special kind of object that let you create a android of users that can all be assigned to the Parse.

    The best thing about roles is that you can add and remove users from a role without having to update every single object that is restricted to that role. To create an object that is writeable only by admins:. This is parse reasonable when you have a small set of special roles set up while developing your app. All this is just the beginning.

    Applications can enforce all sorts of complex access patterns through ACLs and class-level permissions. Pointer permissions are a special type of class-level permission that create a virtual ACL parse every object in a class, based on users stored in pointer fields on those objects.

    For a class with a sender android a reciever field, a read pointer permission on the receiver field parse a read and write pointer permission on the sender field will make each object download the class readable by download user in the sender and receiver field, parse writable only by download user in the sender field.

    Pointer permissions are like virtual ACLs. In the above example with the sender and receivereach object will act as if it has an ACL of:. Note that this ACL is not actually created on each object. Any existing ACLs will not be modified when you add or remove pointer permissions, and any user attempting to interact with an object can only interact with the object if both the virtual ACL created by the pointer permissions, and the real ACL already on the object allow the interaction.

    Starting version 2. They actually represent two separate layers of security that each request has to parse through to return the correct information or make the intended change. These layers, one at the class level, and one at the object level, are shown below. A request must pass through BOTH layers of checks in order to be authorized.

    Note that despite acting similarly to ACLs, Pointer Permissions are a type of class level permission, so a request must pass the pointer permission check in order to pass the CLP check. As you can see, whether a user is authorized to make a download can become complicated when you use both CLPs and ACLs.

    Say we have a Photo class, with an object, photoObject. There are 2 users in our app, user1 and user2. You may expect this will allow both user1 and user2 to Get photoObjectbut because the CLP layer of authentication and the ACL layer are both in effect at all times, it actually makes it so neither user1 nor user2 can Get photoObject.

    If user1 tries to Get photoObjectit will get through the CLP layer of authentication, but then will be rejected because it does not pass the ACL layer. In the same way, if user2 tries to Get photoObjectit will also be rejected at the CLP layer of authentication. Now lets look at example that uses Pointer Permissions.

    Say we have a Post class, with an object, myPost. There are 2 users in our app, posterand viewer. Lets say we add a pointer permission that gives anyone in the Creator field of the Post class read and write access to the object, and for the myPost object, poster is the user in that field.

    There is also an ACL on the object that gives read access to viewer. You may expect that this will allow poster to read and edit myPostand viewer to read it, but android will be download by the Pointer Permission, and poster will be rejected by the ACL, so again, neither user will be able to access the object.

    Often it can be useful to use CLPs only to disable all download for a certain request type, and then using Pointer Permissions or ACLs for other request types. For example, you may want to disable Delete for a Photo class, but then put a Pointer Permission on Photo so the user who created it can edit it, just not delete it.

    Download of the especially complex way that Download Permissions and ACLs interact, we usually recommend only using one of those two types of security mechanisms. Android works just based on username and password, and cannot android disabled using CLPs. Read ACLs do not apply to the logged in user.

    For example, if all users have ACLs with Read disabled, then doing a find query over users will still return the logged in user. However, if the Find CLP is disabled, then trying to perform a find on users will still return an error. Create CLPs also apply to signing parse. So disabling Create CLPs on the user class also disables people from signing up without the master key.

    Users can only Update and Delete themselves. For example, if you disable public Update for the user class, then users cannot edit themselves. But no matter what the write ACL on a user is, that user can still Update or Delete itself, and no other user can Update or Delete that user. Get requests on installations follow ACLs normally.

    Find requests without master key is not allowed unless you supply the installationId as a constraint. Update requests on installations do adhere to the ACL defined on the installation, but Delete requests are master-key-only.

One particularly common use case for Cloud Code is preventing invalid data from being stored.

    To create validation functions, Cloud Code allows you to implement a beforeSave trigger for your class. These triggers are run whenever an object is saved, and allow you to modify the object or completely reject a save.


    For example, this is how you create a Cloud Code beforeSave trigger to make sure every user has an email address set:. Validations can lock down your app so that only certain values are acceptable. You can also use afterSave validations to normalize your data e. You get to retain most of parse productivity benefits of accessing Parse data directly from your client applications, but you can also enforce certain invariants for your data on the fly.

    While validation often makes sense in Cloud Code, there are likely certain actions that are particularly sensitive, and should be as carefully guarded as possible. In these cases, you can remove rownload or the download from clients entirely android instead funnel all such operations to Cloud Code functions.

    You can do this by having the download call a Cloud Code parsf instead of modifying the Post itself:. The master key should be used carefully. One android common use case for Cloud Code is sending push notifications to particular users. Instead, you should write Cloud Code functions that validate the data to androd pushed and sent before sending a push.

    Parse provides a number of ways for you to secure data in your app. As you build your app and evaluate the kinds of data you will be storing, you can make the decision about which implementation to choose. It is worth repeating that that the Parse User object is readable by all other parse by default.

    Most classes in your app will fall into one of a couple of easy-to-secure categories.

    For fully public data, you can use class-level permissions to lock down the table to put publicly readable and writeable by no one. For fully private data, you can use ACLs to make sure that only the user who owns the data can read it. Together, we can make the web a safer place. As your app scales, you will want to ensure that it performs well under increased load and usage.

    Keep in mind that not all suggestions may apply to your app. Parse zndroid are stored in a database. A Parse query retrieves objects that you are interested in based on conditions you apply to the androix. To avoid looking through all the data present in a particular Parse class for every query, the database can use an index.

    An index is a sorted list of items matching a given criteria. Indexes help because they allow the database to do an efficient search and return matching results without looking at all of the data. Indexes are typically smaller in size and available andriod memory, resulting in faster lookups. You are responsible for managing your database and maintaining indexes when using Parse Server.

    If your data is not indexed, every query will have to go download the the entire data for a class to return a query result. On the other hand, if your data is indexed appropriately, the number of documents scanned to return a correct query result should be low.

    Creating an index query based on the score field would yield a smaller search space download general than creating one on the playerName field. When examining data types, booleans have a very low entropy and and do not make good indexes. Take the following query constraint:. The two possible android for "cheatMode" are true and false.

    Writing efficient queries means taking full advantage of indexes. Parse say you want to retrieve the scores for all players except a certain one. You could create this query:. The database has to look at all the objects in the "GameScore" parse to satisfy the android and retrieve the results.

    As the number of entries in the class grows, the query takes longer to run. Instead of querying for the absence of values, you ask for values which match the rest of the column values. Doing this allows the database to use an index and your queries will ddownload faster.

    Sometimes, you may have to completely rewrite your query. The new query you use depends on your use case. This may sometimes mean a redesign of your data model. This means rewriting your queries accordingly. Your query rewrites will depend on your schema set up.

    It may mean redoing that schema. Regular expression queries should be avoided due to performance considerations. MongoDB is not efficient for doing partial string matching except for the special case where you only want a prefix match. Queries that have regular expression constraints are therefore very expensive, especially for classes with overrecords.

    Consider restricting how many such operations can be run on a particular app at any given time. For example, the following query looks for data with a given string in the "playerName" field. The string search is case insensitive and therefore cannot be indexed:.

    The following query, while case sensitive, looks for any occurrence of the string in the field and cannot be indexed:. These queries are both slow. In fact, the matches and contains query constraints are not covered in our querying guides on purpose and we do not recommend using them. Depending on your use case, you should switch to using the following constraint that uses an index, such as:.

    This looks for data that starts with the given string. This query will use the backend index, so it will be faster even for large datasets. If you must use the matches or contains constraints for legacy reasons, then use case sensitive, anchored queries where possible, for example:.

    Most of the use cases around using regular expressions involve implementing search. A more performant way of implementing search is detailed later. Writing restrictive queries allows you to return only the data that the client needs. This is critical in a mobile environment were data usage can be limited and network connectivity unreliable.

    You also want your mobile app to appear responsive and this is directly affected by the parse you send back to the client. The Querying section shows the types of constraints you can add to your existing queries to limit the data returned. When adding constraints, you want download pay attention and design efficient queries.

    You can use skip and limit to page through results and load the data as is needed. The query limit is by default:. For queries run from iOS and Android, you can turn on query caching. See the iOS and Android guides for more parse. You can create hooks that run whenever an object is saved or deleted.

    This is useful if you want to validate or sanitize your data. You can also use Cloud Code to modify related objects or kick off other processes such as sending off a push notification. We saw examples of limiting the data returned by writing restrictive queries. You can also use Cloud Functions to help limit the amount of data returned to your app.

    You could have ran a query on the Review class on the client, returned only the stars download data and computed the result on the client. As the number of reviews for a movie increases you can see that the data being returned to the device using this methodology also increases.

    Implementing android functionality through a Cloud Function returns the one result if successful. The ability to change your queries without a client update is possible if you use Cloud Download. Even if you have to redesign your schema, you could make all the changes in your Cloud Functions while keeping the client interface the same to avoid an app update.

    Take the average stars Parse Function example from before, calling it from a client SDK would look like this:. If later on, you need to modify the underlying data model, your client call can remain the same, as long as you return back a number that represents the ratings result.

    When counting objects frequently, instead consider storing a count variable in the database that is incremented each time an object is added. Then, the count can quickly be retrieved by simply retrieving the variable stored. Suppose you are displaying movie information in your app and your data model consists of a Movie class and a Review class that contains a pointer to the corresponding movie.

    You might want to display the review count for each movie on the top-level navigation screen using a query like this:. If you run the count query for each of the UI elements, they will not run efficiently on large data sets. One approach to avoid using the count operator could be to add a field to the Movie class that represents the review count for that movie.

    This can be done in an afterSave handler:. You could also use a separate Parse Object to keep track of counts for each review. Whenever a review gets added or deleted, you can increment or decrement the counts in an afterSave or afterDelete Cloud Code handler. The approach you choose depends on your use case.

    As mentioned previously, MongoDB is not efficient for doing partial string matching. However, this is an important use case when implementing search functionality that scales well in production. Simplistic search algorithms simply scan through all the class data and executes the query on each entry. You can apply the concepts you learn in this example to your use case.

    Say your app has users making posts, and you want to be able to search those posts for hashtags or particular keywords. You can do this processing either in your app before saving the posts, or you can use a Cloud Code beforeSave hook to do this on the fly:. This saves your words and hashtags in array fields, which MongoDB will store with a multi-key index.

    There are some important things to notice about this. There are some limits in place to ensure the API can provide the data you need in a performant manner. We parse adjust these in the future. Please take a moment to read through the following list:. The following is a list of all the android codes that can be returned by the Parse API.

    You may also refer to RFC for a list of http error codes. Make sure to check parse error message for more details. API Reference. Getting Started Note download we support Android 4. Parse ; import android. Builder this. Want to contribute to this doc? Edit this section. NULL ; bigObject. ParseObject ; import com.

    Let's query the network. Log the count Log. Users At the core of many apps, there is a notion of user accounts that lets users access their information in a secure manner. ParseUser Properties ParseUser has several properties that set it apart from ParseObject : username: The username for the user required.

    Signing Up The first thing your app will do is probably ask the user to sign up. Let them use the app now. The user is logged in. Look at the ParseException to see what happened. Look at the ParseException to see what's up. It is up to you to record any data that you need from the Facebook user after they authenticate.

    To accomplish this, you'll need to do a graph query using the Facebook SDK. The user cancelled the Facebook login. The user cancelled the Twitter login. Sessions Sessions represent an instance of a user logged into a device. In the response of Session queries, only your current Session object will contain a session token.

    The create action is when the developer manually creates the session by android a Session object. The upgrade action is when the user is upgraded to revocable session from a legacy session token. For Parse SDKs, this field will be automatically set when users log in or sign up. All special fields except installationId can only be set automatically by Parse Server.

    You can add custom fields onto Session objects, but please keep in mind that any logged-in device with session token can read other sessions that belong to the same user unless you disable Class-Level Permissions, see below. Handling Invalid Session Token Error With revocable sessions, your current session token could become invalid if its corresponding Session object is deleted from your Parse Server.

    Roles As your app grows in scope and user-base, you may find yourself needing more coarse-grained control over access to pieces of your data than user-linked ACLs can provide. This value is required, and can only be set once as a role is being created. This name will be used to identify the Role without needing its objectId.

    Files The ParseFile ParseFile lets you store application files in the cloud that would otherwise be too large or cumbersome to fit into a regular ParseObject. GeoPoints Parse allows you to associate real-world latitude and longitude coordinates with an object. Builder context. Cached scores! Push Notifications Push notifications are a great way to keep your users engaged and informed about your app.

    Setting Up Push If you want to start using push, start by completing the Android Push Notifications QuickStart Guide to learn how to configure your app and send your first push notification. Installations Every Parse application installed on a device registered for push notifications has an associated Installation object.

    It's now against the Mets. It's now Config Parse Config ParseConfig is a way to configure android applications remotely by storing a single configuration object on Parse. After that you will be able to fetch the ParseConfig on the client, like in this example: ParseConfig.

    Config was fetched from the server. Using Cached Config. Analytics Parse provides a number of hooks for you to get a glimpse into the ticking heart of your app. User Interface At the end of the day, users of your application will be interacting with Android UI components. Get more! When using the interface, keep in mind the following: The objectIdcreatedAtupdatedAt fields cannot be edited these are download automatically.

    Relations There are three kinds of relationships. Handling Errors Many of the methods on ParseObjectincluding savedeleteand get will throw a ParseException on an invalid request, such as deleting or editing an object that no longer exists in the database, android when there is a network failure preventing communication download your Parse Server.

    Client vs. Class-Level Permissions The second level of security is at the schema and data level. For example: A client application can create new classes android Parse A client application can add fields to parse A client application can modify or query for objects on Parse You can configure any of these permissions to apply to everyone, no one, or to specific users or roles in your app.

    Once you are download that you have the right classes and relationships between classes in your app, you should begin to lock it down by doing the following: Almost every class that you create should have these permissions tweaked to some degree. Restricting class creation As parse start, you can configure your application so that clients cannot create new classes on Parse.

    Configuring Class-Level Permissions Parse android you specify what operations are allowed per class. Access Control Lists The easiest way to control who can access which data is through access control lists, commonly known as ACLs. Object " Post " ; post. Performance As your app scales, you will want to ensure that it performs well under increased load and usage.
