ActivityCompat

Helper for accessing features in Activity.

Summary

Nested classes
`interface`	`ActivityCompat.OnRequestPermissionsResultCallback` This interface is the contract for receiving the results for permission requests.
`interface`	`ActivityCompat.PermissionCompatDelegate` Customizable delegate that allows delegating permission compatibility methods to a custom implementation.

Protected constructors
`ActivityCompat()` This class should not be instantiated, but the constructor must be visible for the class to be extended (as in support-v13).

Public methods
`static void`	`finishAffinity(Activity activity)` Finish this activity, and tries to finish all activities immediately below it in the current task that have the same affinity.
`static void`	`finishAfterTransition(Activity activity)` Reverses the Activity Scene entry Transition and triggers the calling Activity to reverse its exit Transition.
`static Uri`	`getReferrer(Activity activity)` Return information about who launched this activity.
`static boolean`	`invalidateOptionsMenu(Activity activity)` This method was deprecated in API level 27.1.0. Use `invalidateOptionsMenu()` directly.
`static void`	`postponeEnterTransition(Activity activity)`
`static DragAndDropPermissionsCompat`	`requestDragAndDropPermissions(Activity activity, DragEvent dragEvent)` Create `DragAndDropPermissionsCompat` object bound to this activity and controlling the access permissions for content URIs associated with the `DragEvent`.
`static void`	`requestPermissions(Activity activity, String[] permissions, int requestCode)` Requests permissions to be granted to this application.
`static <T extends View> T`	`requireViewById(Activity activity, int id)` Finds a view that was identified by the `android:id` XML attribute that was processed in `onCreate(Bundle)`, or throws an IllegalArgumentException if the ID is invalid, or there is no matching view in the hierarchy.
`static void`	`setEnterSharedElementCallback(Activity activity, SharedElementCallback callback)` When `makeSceneTransitionAnimation(Activity, android.view.View, String)` was used to start an Activity, `callback` will be called to handle shared elements on the launched Activity.
`static void`	`setExitSharedElementCallback(Activity activity, SharedElementCallback callback)` When `makeSceneTransitionAnimation(Activity, android.view.View, String)` was used to start an Activity, `callback` will be called to handle shared elements on the launching Activity.
`static void`	`setPermissionCompatDelegate(ActivityCompat.PermissionCompatDelegate delegate)` Sets the permission delegate for `ActivityCompat`.
`static boolean`	`shouldShowRequestPermissionRationale(Activity activity, String permission)` Gets whether you should show UI with rationale for requesting a permission.
`static void`	`startActivityForResult(Activity activity, Intent intent, int requestCode, Bundle options)` Start new activity with options, if able, for which you would like a result when it finished.
`static void`	`startIntentSenderForResult(Activity activity, IntentSender intent, int requestCode, Intent fillInIntent, int flagsMask, int flagsValues, int extraFlags, Bundle options)` Start new IntentSender with options, if able, for which you would like a result when it finished.
`static void`	`startPostponedEnterTransition(Activity activity)`

Inherited methods

From class


  
    android.support.v4.content.ContextCompat

`static int`	`checkSelfPermission(Context context, String permission)` Determine whether you have been granted a particular permission.
`static Context`	`createDeviceProtectedStorageContext(Context context)` Return a new Context object for the current Context but whose storage APIs are backed by device-protected storage.
`static File`	`getCodeCacheDir(Context context)` Returns the absolute path to the application specific cache directory on the filesystem designed for storing cached code.
`static int`	`getColor(Context context, int id)` Returns a color associated with a particular resource ID Starting in `M`, the returned color will be styled for the specified Context's theme.
`static ColorStateList`	`getColorStateList(Context context, int id)` Returns a color state list associated with a particular resource ID.

`static File[]`	`getExternalFilesDirs(Context context, String type)` Returns absolute paths to application-specific directories on all external storage devices where the application can place persistent files it owns.
`static File`	`getNoBackupFilesDir(Context context)` Returns the absolute path to the directory on the filesystem similar to `getFilesDir()`.
`static File[]`	`getObbDirs(Context context)` Returns absolute paths to application-specific directories on all external storage devices where the application's OBB files (if there are any) can be found.
`static <T> T`	`getSystemService(Context context, Class<T> serviceClass)` Return the handle to a system-level service by class.
`static String`	`getSystemServiceName(Context context, Class<?> serviceClass)` Gets the name of the system-level service that is represented by the specified class.
`static boolean`	`isDeviceProtectedStorage(Context context)` Indicates if the storage APIs of this Context are backed by device-encrypted storage.
`static boolean`	`startActivities(Context context, Intent[] intents, Bundle options)` Start a set of activities as a synthesized task stack, if able.
`static boolean`	`startActivities(Context context, Intent[] intents)` Start a set of activities as a synthesized task stack, if able.
`static void`	`startActivity(Context context, Intent intent, Bundle options)` Start an activity with additional launch information, if able.
`static void`	`startForegroundService(Context context, Intent intent)` startForegroundService() was introduced in O, just call startService for before O.

ActivityCompat

added in version 22.1.0

ActivityCompat ()

This class should not be instantiated, but the constructor must be visible for the class to be extended (as in support-v13).

Public methods

finishAffinity

added in version 22.1.0

void finishAffinity (Activity activity)

Finish this activity, and tries to finish all activities immediately below it in the current task that have the same affinity.

On Android 4.1+ calling this method will call through to the native version of this method. For other platforms finish() will be called instead.

Parameters
`activity`	`Activity`

finishAfterTransition

added in version 22.1.0

void finishAfterTransition (Activity activity)

Reverses the Activity Scene entry Transition and triggers the calling Activity to reverse its exit Transition. When the exit Transition completes, finish() is called. If no entry Transition was used, finish() is called immediately and the Activity exit Transition is run.

On Android 4.4 or lower, this method only finishes the Activity with no special exit transition.

Parameters
`activity`	`Activity`

getReferrer

added in version 24.1.0

Uri getReferrer (Activity activity)

Return information about who launched this activity. If the launching Intent contains an Intent.EXTRA_REFERRER, that will be returned as-is; otherwise, if known, an android-app: referrer URI containing the package name that started the Intent will be returned. This may return null if no referrer can be identified -- it is neither explicitly specified, nor is it known which application package was involved.

If called while inside the handling of onNewIntent(Intent), this function will return the referrer that submitted that new intent to the activity. Otherwise, it always returns the referrer of the original Intent.

Note that this is not a security feature -- you can not trust the referrer information, applications can spoof it.

Parameters
`activity`	`Activity`

Returns
`Uri`
