Determine whether the calling process of an IPC or you has been granted permission to access a list of URIs. This is the same as checkCallingUriPermission, except it grants your own permissions if you are not currently processing an IPC. Use with care!

Determine whether the calling process and uid has been granted permission to access a list of URIs. This is basically the same as calling checkUriPermissions(java.util.List,int,int,int) with the pid and uid returned by android.os.Binder#getCallingPid and android.os.Binder#getCallingUid. One important difference is that if you are not currently processing an IPC, this function will always fail.

Determine whether a particular process and uid has been granted permission to access a specific content URI.

Unlike checkUriPermission(android.net.Uri,int,int,int), this method checks for general access to the URI's content provider, as well as explicitly granted permissions.

Note, this check will throw an IllegalArgumentException for non-content URIs.

Check both a Uri and normal permission. This allows you to perform both checkPermission and #checkUriPermission in one call.

Determine whether a particular process and uid has been granted permission to access a list of URIs. This only checks for permissions that have been explicitly granted -- if the given process/uid has more general access to the URI's content provider then this check will always fail. Note: On SDK Version android.os.Build.VERSION_CODES#S, calling this method from a secondary-user's context will incorrectly return PackageManager#PERMISSION_DENIED for all {code uris}.

Return a new Context object for the current Context but attribute to a different tag. In complex apps attribution tagging can be used to distinguish between separate logical parts.

Creates a context with specific properties and behaviors.

Returns a new Context object from the current context but with device association given by the deviceId. Each call to this method returns a new instance of a context object. Context objects are not shared; however, common state (such as the ClassLoader and other resources for the same configuration) can be shared, so the Context itself is lightweight.

Applications that run on virtual devices may use this method to access the default device capabilities and functionality (by passing Context#DEVICE_ID_DEFAULT. Similarly, applications running on the default device may access the functionality of virtual devices.

Note that the newly created instance will be associated with the same display as the parent Context, regardless of the device ID passed here.

Creates a Context for a non-activity window.

A window context is a context that can be used to add non-activity windows, such as android.view.WindowManager.LayoutParams#TYPE_APPLICATION_OVERLAY. A window context must be created from a context that has an associated Display, such as Activity or a context created with createDisplayContext(android.view.Display).

The window context is created with the appropriate Configuration for the area of the display that the windows created with it can occupy; it must be used when inflating views, such that they can be inflated with proper Resources. Below is a sample code to add an application overlay window on the primary display:

...
  final DisplayManager dm = anyContext.getSystemService(DisplayManager.class);
  final Display primaryDisplay = dm.getDisplay(DEFAULT_DISPLAY);
  final Context windowContext = anyContext.createDisplayContext(primaryDisplay)
          .createWindowContext(TYPE_APPLICATION_OVERLAY, null);
  final View overlayView = Inflater.from(windowContext).inflate(someLayoutXml, null);
 
  // WindowManager.LayoutParams initialization
  ...
  // The types used in addView and createWindowContext must match.
  mParams.type = TYPE_APPLICATION_OVERLAY;
  ...
 
  windowContext.getSystemService(WindowManager.class).addView(overlayView, mParams);
  

This context's configuration and resources are adjusted to an area of the display where the windows with provided type will be added. Note that all windows associated with the same context will have an affinity and can only be moved together between different displays or areas on a display. If there is a need to add different window types, or non-associated windows, separate Contexts should be used.

Creating a window context is an expensive operation. Misuse of this API may lead to a huge performance drop. The best practice is to use the same window context when possible. An approach is to create one window context with specific window type and display and use it everywhere it's needed.

After Build.VERSION_CODES#S, window context provides the capability to receive configuration changes for existing token by overriding the token of the android.view.WindowManager.LayoutParams passed in WindowManager#addView(View, LayoutParams). This is useful when an application needs to attach its window to an existing activity for window token sharing use-case.

Note that the window context in Build.VERSION_CODES#R didn't have this capability. This is a no-op for the window context in Build.VERSION_CODES#R.

final DisplayManager dm = anyContext.getSystemService(DisplayManager.class);
  final Display primaryDisplay = dm.getDisplay(DEFAULT_DISPLAY);
  final Context windowContext = anyContext.createWindowContext(primaryDisplay,
          TYPE_APPLICATION, null);
 
  // Get an existing token.
  final IBinder existingToken = activity.getWindow().getAttributes().token;
 
  // The types used in addView() and createWindowContext() must match.
  final WindowManager.LayoutParams params = new WindowManager.LayoutParams(TYPE_APPLICATION);
  params.token = existingToken;
 
  // After WindowManager#addView(), the server side will extract the provided token from
  // LayoutParams#token (existingToken in the sample code), and switch to propagate
  // configuration changes from the node associated with the provided token.
  windowContext.getSystemService(WindowManager.class).addView(overlayView, mParams);
  

After Build.VERSION_CODES#S, window context provides the capability to listen to its Configuration changes by calling registerComponentCallbacks(android.content.ComponentCallbacks), while other kinds of Context will register the ComponentCallbacks to its. Note that window context only propagate ComponentCallbacks#onConfigurationChanged(Configuration) callback. ComponentCallbacks#onLowMemory() or other callbacks in ComponentCallbacks2 won't be invoked.

Note that using android.app.Application or android.app.Service context for UI-related queries may result in layout or continuity issues on devices with variable screen sizes (e.g. foldables) or in multi-window modes, since these non-UI contexts may not reflect the Configuration changes for the visual container.

Creates a Context for a non-activity window on the given Display.

Similar to createWindowContext(int,android.os.Bundle), but the display is passed in, instead of implicitly using the original Context's Display.

If neither you nor the calling process of an IPC you are handling has been granted a particular permission, throw a SecurityException. This is the same as enforceCallingPermission, except it grants your own permissions if you are not currently processing an IPC. Use with care!

If the calling process of an IPC you are handling has not been granted a particular permission, throw a SecurityException. This is basically the same as calling enforcePermission(java.lang.String,int,int,java.lang.String) with the pid and uid returned by android.os.Binder#getCallingPid and android.os.Binder#getCallingUid. One important difference is that if you are not currently processing an IPC, this function will always throw the SecurityException. This is done to protect against accidentally leaking permissions; you can use enforceCallingOrSelfPermission to avoid this protection.

If the given permission is not allowed for a particular process and user ID running in the system, throw a SecurityException.

Enforce both a Uri and normal permission. This allows you to perform both enforcePermission and #enforceUriPermission in one call.

Get the display this context is associated with. Applications should use this method with android.app.Activity or a context associated with a Display via createDisplayContext(android.view.Display) to get a display object associated with a Context, or android.hardware.display.DisplayManager#getDisplay to get a display object by id.

Returns absolute path to application-specific directory on the primary shared/external storage device where the application can place cache files it owns. These files are internal to the application, and not typically visible to the user as media.

This is like getCacheDir() in that these files will be deleted when the application is uninstalled, however there are some important differences:

• The platform does not always monitor the space available in shared storage, and thus may not automatically delete these files. Apps should always manage the maximum space used in this location. Currently the only time files here will be deleted by the platform is when running on android.os.Build.VERSION_CODES#JELLY_BEAN_MR1 or later and Environment#isExternalStorageEmulated(File) returns true.
• Shared storage may not always be available, since removable media can be ejected by the user. Media state can be checked using Environment#getExternalStorageState(File).
• There is no security enforced with these files. For example, any application holding android.Manifest.permission#WRITE_EXTERNAL_STORAGE can write to these files.

If a shared storage device is emulated (as determined by Environment#isExternalStorageEmulated(File)), its contents are backed by a private user data partition, which means there is little benefit to storing data here instead of the private directory returned by getCacheDir().

Starting in android.os.Build.VERSION_CODES#KITKAT, no permissions are required to read or write to the returned path; it's always accessible to the calling app. This only applies to paths generated for package name of the calling application. To access paths belonging to other packages, android.Manifest.permission#WRITE_EXTERNAL_STORAGE and/or android.Manifest.permission#READ_EXTERNAL_STORAGE are required.

On devices with multiple users (as described by UserManager), each user has their own isolated shared storage. Applications only have access to the shared storage for the user they're running as.

The returned path may change over time if different shared storage media is inserted, so only relative paths should be persisted.

Returns the absolute path to the directory on the primary shared/external storage device where the application can place persistent files it owns. These files are internal to the applications, and not typically visible to the user as media.

This is like getFilesDir() in that these files will be deleted when the application is uninstalled, however there are some important differences:

• Shared storage may not always be available, since removable media can be ejected by the user. Media state can be checked using Environment#getExternalStorageState(File).
• There is no security enforced with these files. For example, any application holding android.Manifest.permission#WRITE_EXTERNAL_STORAGE can write to these files.

If a shared storage device is emulated (as determined by Environment#isExternalStorageEmulated(File)), its contents are backed by a private user data partition, which means there is little benefit to storing data here instead of the private directories returned by getFilesDir(), etc.

Starting in android.os.Build.VERSION_CODES#KITKAT, no permissions are required to read or write to the returned path; it's always accessible to the calling app. This only applies to paths generated for package name of the calling application. To access paths belonging to other packages, android.Manifest.permission#WRITE_EXTERNAL_STORAGE and/or android.Manifest.permission#READ_EXTERNAL_STORAGE are required.

On devices with multiple users (as described by UserManager), each user has their own isolated shared storage. Applications only have access to the shared storage for the user they're running as.

The returned path may change over time if different shared storage media is inserted, so only relative paths should be persisted.

Here is an example of typical code to manipulate a file in an application's shared storage:

If you supply a non-null type to this function, the returned file will be a path to a sub-directory of the given type. Though these files are not automatically scanned by the media scanner, you can explicitly add them to the media database with MediaScannerConnection.scanFile. Note that this is not the same as Environment.getExternalStoragePublicDirectory(), which provides directories of media shared by all applications. The directories returned here are owned by the application, and their contents will be removed when the application is uninstalled. Unlike Environment.getExternalStoragePublicDirectory(), the directory returned here will be automatically created for you.

Here is an example of typical code to manipulate a picture in an application's shared storage and add it to the media database:

Return the set of parameters which this Context was created with, if it was created via createContext(android.content.ContextParams).

Open a new private SQLiteDatabase associated with this Context's application package. Creates the database file if it doesn't exist.

Accepts input param: a concrete instance of DatabaseErrorHandler to be used to handle corruption when sqlite reports database corruption.

Add a new ComponentCallbacks to the base application of the Context, which will be called at the same times as the ComponentCallbacks methods of activities and other components are called. Note that you must be sure to use unregisterComponentCallbacks when appropriate in the future; this will not be removed for you.

After Build.VERSION_CODES#TIRAMISU, the ComponentCallbacks will be registered to the base Context, and can be only used after attachBaseContext(android.content.Context). Users can still call to getApplicationContext().registerComponentCallbacks(ComponentCallbacks) to add ComponentCallbacks to the base application.

Adds a new device ID changed listener to the Context, which will be called when the device association is changed by the system.

The callback can be called when an app is moved to a different device and the Context is not explicitly associated with a specific device.

When an application receives a device id update callback, this Context is guaranteed to also have an updated display ID(if any) and Configuration.

Register a BroadcastReceiver to be run in the main activity thread. The receiver will be called with any broadcast Intent that matches filter, in the main application thread.

The system may broadcast Intents that are "sticky" -- these stay around after the broadcast has finished, to be sent to any later registrations. If your IntentFilter matches one of these sticky Intents, that Intent will be returned by this function and sent to your receiver as if it had just been broadcast.

There may be multiple sticky Intents that match filter, in which case each of these will be sent to receiver. In this case, only one of these can be returned directly by the function; which of these that is returned is arbitrarily decided by the system.

If you know the Intent your are registering for is sticky, you can supply null for your receiver. In this case, no receiver is registered -- the function simply returns the sticky Intent that matches filter. In the case of multiple matches, the same rules as described above apply.

See BroadcastReceiver for more information on Intent broadcasts.

As of android.os.Build.VERSION_CODES#UPSIDE_DOWN_CAKE, the system can place context-registered broadcasts in a queue while the app is in the cached state. When the app leaves the cached state, such as returning to the foreground, the system delivers any queued broadcasts. Multiple instances of certain broadcasts might be merged into one broadcast.

As of android.os.Build.VERSION_CODES#ICE_CREAM_SANDWICH, receivers registered with this method will correctly respect the Intent#setPackage(String) specified for an Intent being broadcast. Prior to that, it would be ignored and delivered to all matching registered receivers. Be careful if using this for security.

For apps targeting android.os.Build.VERSION_CODES#UPSIDE_DOWN_CAKE, either RECEIVER_EXPORTED or RECEIVER_NOT_EXPORTED must be specified if the receiver is not being registered for system broadcasts or a SecurityException will be thrown. See registerReceiver(android.content.BroadcastReceiver,android.content.IntentFilter,int) to register a receiver with flags.

Note: this method cannot be called from a BroadcastReceiver component; that is, from a BroadcastReceiver that is declared in an application's manifest. It is okay, however, to call this method from another BroadcastReceiver that has itself been registered at run time with #registerReceiver, since the lifetime of such a registered BroadcastReceiver is tied to the object that registered it.

Register to receive intent broadcasts, with the receiver optionally being exposed to Instant Apps. See registerReceiver(android.content.BroadcastReceiver,android.content.IntentFilter) for more information. By default Instant Apps cannot interact with receivers in other applications, this allows you to expose a receiver that Instant Apps can interact with.

Register to receive intent broadcasts, to run in the context of scheduler. See registerReceiver(android.content.BroadcastReceiver,android.content.IntentFilter) for more information. This allows you to enforce permissions on who can broadcast intents to your receiver, or have the receiver run in a different thread than the main application thread.

Triggers the revocation of one or more permissions for the calling package. A package is only able to revoke runtime permissions. If a permission is not currently granted, it is ignored and will not get revoked (even if later granted by the user). Ultimately, you should never make assumptions about a permission status as users may grant or revoke them at any time.

Background permissions which have no corresponding foreground permission still granted once the revocation is effective will also be revoked.

The revocation happens asynchronously and kills all processes running in the calling UID. It will be triggered once it is safe to do so. In particular, it will not be triggered as long as the package remains in the foreground, or has any active manifest components (e.g. when another app is accessing a content provider in the package).

If you want to revoke the permissions right away, you could call System.exit() in Handler.postDelayed with a delay to allow completion of async IPC, But System.exit() could affect other apps that are accessing your app at the moment. For example, apps accessing a content provider in your app will all crash.

Note that the settings UI shows a permission group as granted as long as at least one permission in the group is granted. If you want the user to observe the revocation in the settings, you should revoke every permission in the target group. To learn the current list of permissions in a group, you may use PackageManager#getGroupOfPlatformPermission(String, Executor, Consumer) and PackageManager#getPlatformPermissionsForGroup(String, Executor, Consumer). This list of permissions may evolve over time, so it is recommended to check whether it contains any permission you wish to retain before trying to revoke an entire group.

Broadcast the given intent to all interested BroadcastReceivers, allowing an optional required permission to be enforced. This call is asynchronous; it returns immediately, and you will continue executing while the receivers are run. No results are propagated from receivers and receivers can not abort the broadcast. If you want to allow receivers to propagate results or abort the broadcast, you must send an ordered broadcast using sendOrderedBroadcast(android.content.Intent,java.lang.String).

Version of sendBroadcast(android.content.Intent) that allows you to receive data back from the broadcast. This is accomplished by supplying your own BroadcastReceiver when calling, which will be treated as a final receiver at the end of the broadcast -- its BroadcastReceiver#onReceive method will be called with the result values collected from the other receivers. The broadcast will be serialized in the same way as calling sendOrderedBroadcast(android.content.Intent,java.lang.String).

Like sendBroadcast(android.content.Intent), this method is asynchronous; it will return before resultReceiver.onReceive() is called.

Version of sendOrderedBroadcast(android.content.Intent,java.lang.String,android.content.BroadcastReceiver,android.os.Handler,int,java.lang.String,android.os.Bundle) that allows you to specify the App Op to enforce restrictions on which receivers the broadcast will be sent to.

See BroadcastReceiver for more information on Intent broadcasts.

Version of sendOrderedBroadcast(android.content.Intent,java.lang.String,android.content.BroadcastReceiver,android.os.Handler,int,java.lang.String,android.os.Bundle) that allows you to specify the user the broadcast will be sent to. This is not available to applications that are not pre-installed on the system image.

See BroadcastReceiver for more information on Intent broadcasts.
Requires android.Manifest.permission.INTERACT_ACROSS_USERS

Perform a sendBroadcast(android.content.Intent) that is "sticky," meaning the Intent you are sending stays around after the broadcast is complete, so that others can quickly retrieve that data through the return value of registerReceiver(android.content.BroadcastReceiver,android.content.IntentFilter). In all other ways, this behaves the same as sendBroadcast(android.content.Intent).

Version of #sendStickyBroadcast that allows you to receive data back from the broadcast. This is accomplished by supplying your own BroadcastReceiver when calling, which will be treated as a final receiver at the end of the broadcast -- its BroadcastReceiver#onReceive method will be called with the result values collected from the other receivers. The broadcast will be serialized in the same way as calling sendOrderedBroadcast(android.content.Intent,java.lang.String).

Like sendBroadcast(android.content.Intent), this method is asynchronous; it will return before resultReceiver.onReceive() is called. Note that the sticky data stored is only the data you initially supply to the broadcast, not the result of any changes made by the receivers.

See BroadcastReceiver for more information on Intent broadcasts.
Requires android.Manifest.permission#BROADCAST_STICKY

Version of sendStickyOrderedBroadcast(android.content.Intent,android.content.BroadcastReceiver,android.os.Handler,int,java.lang.String,android.os.Bundle) that allows you to specify the user the broadcast will be sent to. This is not available to applications that are not pre-installed on the system image.

See BroadcastReceiver for more information on Intent broadcasts.
Requires android.Manifest.permission.INTERACT_ACROSS_USERS and android.Manifest.permission#BROADCAST_STICKY

Launch multiple new activities. This is generally the same as calling startActivity(android.content.Intent) for the first Intent in the array, that activity during its creation calling startActivity(android.content.Intent) for the second entry, etc. Note that unlike that approach, generally none of the activities except the last in the array will be created at this point, but rather will be created when the user first visits them (due to pressing back from the activity on top).

This method throws ActivityNotFoundException if there was no Activity found for any given Intent. In this case the state of the activity stack is undefined (some Intents in the list may be on it, some not), so you probably want to avoid such situations.

Launch a new activity. You will not receive any information about when the activity exits.

Note that if this method is being called from outside of an android.app.Activity Context, then the Intent must include the Intent#FLAG_ACTIVITY_NEW_TASK launch flag. This is because, without being started from an existing Activity, there is no existing task in which to place the new activity and thus it needs to be placed in its own separate task.

This method throws ActivityNotFoundException if there was no Activity found to run the given Intent.

Similar to startService(android.content.Intent), but with an implicit promise that the Service will call startForeground(int, android.app.Notification) once it begins running. The service is given an amount of time comparable to the ANR interval to do this, otherwise the system will automatically crash the process, in which case an internal exception ForegroundServiceDidNotStartInTimeException is logged on logcat on devices running SDK Version android.os.Build.VERSION_CODES#S or later. On older Android versions, an internal exception RemoteServiceException is logged instead, with a corresponding message.

Unlike the ordinary startService(android.content.Intent), this method can be used at any time, regardless of whether the app hosting the service is in a foreground state.

Note: Beginning with SDK Version android.os.Build.VERSION_CODES#S, apps targeting SDK Version android.os.Build.VERSION_CODES#S or higher are not allowed to start foreground services from the background. See Behavior changes: Apps targeting Android 12 for more details.

Start executing an android.app.Instrumentation class. The given Instrumentation component will be run by killing its target application (if currently running), starting the target process, instantiating the instrumentation component, and then letting it drive the application.

This function is not synchronous -- it returns as soon as the instrumentation has started and while it is running.

Instrumentation is normally only allowed to run against a package that is either unsigned or signed with a signature that the the instrumentation package is also signed with (ensuring the target trusts the instrumentation).

Same as startIntentSender(android.content.IntentSender,android.content.Intent,int,int,int,android.os.Bundle) with no options specified.

Like startActivity(android.content.Intent,android.os.Bundle), but taking a IntentSender to start. If the IntentSender is for an activity, that activity will be started as if you had called the regular startActivity(android.content.Intent) here; otherwise, its associated action will be executed (such as sending a broadcast) as if you had called android.content.IntentSender#sendIntent on it.

Request that a given application service be started. The Intent should either contain the complete class name of a specific service implementation to start, or a specific package name to target. If the Intent is less specified, it logs a warning about this. In this case any of the multiple matching services may be used. If this service is not already running, it will be instantiated and started (creating a process for it if needed); if it is running then it remains running.

Every call to this method will result in a corresponding call to the target service's android.app.Service#onStartCommand method, with the intent given here. This provides a convenient way to submit jobs to a service without having to bind and call on to its interface.

Using startService() overrides the default service lifetime that is managed by #bindService: it requires the service to remain running until stopService is called, regardless of whether any clients are connected to it. Note that calls to startService() do not nest: no matter how many times you call startService(), a single call to stopService will stop it.

The system attempts to keep running services around as much as possible. The only time they should be stopped is if the current foreground application is using so many resources that the service needs to be killed. If any errors happen in the service's process, it will automatically be restarted.

This function will throw SecurityException if you do not have permission to start the given service.

Note: Each call to startService() results in significant work done by the system to manage service lifecycle surrounding the processing of the intent, which can take multiple milliseconds of CPU time. Due to this cost, startService() should not be used for frequent intent delivery to a service, and only for scheduling significant work. Use #bindService for high frequency calls.

Note: Beginning with SDK Version android.os.Build.VERSION_CODES#S, apps targeting SDK Version android.os.Build.VERSION_CODES#S or higher are not allowed to start foreground services from the background. See Behavior changes: Apps targeting Android 12 for more details.

Remove a ComponentCallbacks object that was previously registered with registerComponentCallbacks(android.content.ComponentCallbacks).

After Build.VERSION_CODES#TIRAMISU, the ComponentCallbacks will be unregistered to the base Context, and can be only used after attachBaseContext(android.content.Context)

Removes a device ID changed listener from the Context. It's a no-op if the listener is not already registered.

See bindIsolatedService(android.content.Intent,int,java.lang.String,java.util.concurrent.Executor,android.content.ServiceConnection) Call BindServiceFlags#of(long) to obtain a BindServiceFlags object.

Returns a color associated with a particular resource ID and styled for the current theme.

Returns a color state list associated with a particular resource ID and styled for the current theme.

Returns a drawable object associated with a particular resource ID and styled for the current theme.

Returns a localized string from the application's package's default string table.

Returns a localized formatted string from the application's package's default string table, substituting the format arguments as defined in java.util.Formatter and java.lang.String#format.

Return the handle to a system-level service by class.

Currently available classes are: android.view.WindowManager, android.view.LayoutInflater, android.app.ActivityManager, android.os.PowerManager, android.app.AlarmManager, android.app.NotificationManager, android.app.KeyguardManager, android.location.LocationManager, android.app.SearchManager, android.os.Vibrator, android.net.ConnectivityManager, android.net.wifi.WifiManager, android.media.AudioManager, android.media.MediaRouter, android.telephony.TelephonyManager, android.telephony.SubscriptionManager, android.view.inputmethod.InputMethodManager, android.app.UiModeManager, android.app.DownloadManager, android.os.BatteryManager, android.app.job.JobScheduler, android.app.usage.NetworkStatsManager, android.content.pm.verify.domain.DomainVerificationManager, android.view.displayhash.DisplayHashManager.

Note: System services obtained via this API may be closely associated with the Context in which they are obtained from. In general, do not share the service objects between various different contexts (Activities, Applications, Services, Providers, etc.)

Note: Instant apps, for which PackageManager#isInstantApp() returns true, don't have access to the following system services: DEVICE_POLICY_SERVICE, FINGERPRINT_SERVICE, KEYGUARD_SERVICE, SHORTCUT_SERVICE, USB_SERVICE, WALLPAPER_SERVICE, WIFI_P2P_SERVICE, WIFI_SERVICE, WIFI_AWARE_SERVICE. For these services this method will return null. Generally, if you are running as an instant app you should always check whether the result of this method is null.

Return a localized, styled CharSequence from the application's package's default string table.

Retrieve styled attribute information in this Context's theme. See android.content.res.Resources.Theme#obtainStyledAttributes(int[]) for more information.

Retrieve styled attribute information in this Context's theme. See android.content.res.Resources.Theme#obtainStyledAttributes(int, int[]) for more information.

Retrieve styled attribute information in this Context's theme. See android.content.res.Resources.Theme#obtainStyledAttributes(AttributeSet, int[], int, int) for more information.

Retrieve styled attribute information in this Context's theme. See android.content.res.Resources.Theme#obtainStyledAttributes(AttributeSet, int[], int, int) for more information.

Triggers the asynchronous revocation of a runtime permission. If the permission is not currently granted, nothing happens (even if later granted by the user).

Broadcast the given intent to all interested BroadcastReceivers, allowing an array of required permissions to be enforced. This call is asynchronous; it returns immediately, and you will continue executing while the receivers are run. No results are propagated from receivers and receivers can not abort the broadcast. If you want to allow receivers to propagate results or abort the broadcast, you must send an ordered broadcast using sendOrderedBroadcast(android.content.Intent,java.lang.String).

See BroadcastReceiver for more information on Intent broadcasts.
