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`	`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 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)`

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`

invalidateOptionsMenu

added in version 22.1.0

boolean invalidateOptionsMenu (Activity activity)

This method was deprecated in API level 27.1.0.
Use invalidateOptionsMenu() directly.

Invalidate the activity's options menu, if able.

Before API level 11 (Android 3.0/Honeycomb) the lifecycle of the options menu was controlled primarily by the user's operation of the hardware menu key. When the user presses down on the menu key for the first time the menu was created and prepared by calls to onCreateOptionsMenu(android.view.Menu) and onPrepareOptionsMenu(android.view.Menu) respectively. Subsequent presses of the menu key kept the existing instance of the Menu itself and called onPrepareOptionsMenu(android.view.Menu) to give the activity an opportunity to contextually alter the menu before the menu panel was shown.

In Android 3.0+ the Action Bar forces the options menu to be built early so that items chosen to show as actions may be displayed when the activity first becomes visible. The Activity method invalidateOptionsMenu forces the entire menu to be destroyed and recreated from onCreateOptionsMenu(android.view.Menu), offering a similar though heavier-weight opportunity to change the menu's contents. Normally this functionality is used to support a changing configuration of Fragments.

Applications may use this support helper to signal a significant change in activity state that should cause the options menu to be rebuilt. If the app is running on an older platform version that does not support menu invalidation the app will still receive onPrepareOptionsMenu(android.view.Menu) the next time the user presses the menu key and this method will return false. If this method returns true the options menu was successfully invalidated.

Parameters
`activity`	`Activity`: Invalidate the options menu of this activity

Returns
`boolean`	true if this operation was supported and it completed; false if it was not available.
