Public Methods

public 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.

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.

public static 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.

public static boolean invalidateOptionsMenu (Activity activity)

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 Invalidate the options menu of this activity
Returns
  • true if this operation was supported and it completed; false if it was not available.

public static void postponeEnterTransition (Activity activity)

public 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. This requires FEATURE_CONTENT_TRANSITIONS.

Parameters
callback Used to manipulate shared element transitions on the launched Activity.

public 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. Most calls will only come when returning from the started Activity. This requires FEATURE_CONTENT_TRANSITIONS.

Parameters
callback Used to manipulate shared element transitions on the launching Activity.

public static void startActivity (Activity activity, Intent intent, Bundle options)

Start an activity with additional launch information, if able.

In Android 4.1+ additional options were introduced to allow for more control on activity launch animations. Applications can use this method along with ActivityOptionsCompat to use these animations when available. When run on versions of the platform where this feature does not exist the activity will be launched normally.

Parameters
activity Context to launch activity from.
intent The description of the activity to start.
options Additional options for how the Activity should be started. May be null if there are no options. See ActivityOptionsCompat for how to build the Bundle supplied here; there are no supported definitions for building it manually.

public 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.

In Android 4.1+ additional options were introduced to allow for more control on activity launch animations. Applications can use this method along with ActivityOptionsCompat to use these animations when available. When run on versions of the platform where this feature does not exist the activity will be launched normally.

Parameters
activity Origin activity to launch from.
intent The description of the activity to start.
requestCode If >= 0, this code will be returned in onActivityResult() when the activity exits.
options Additional options for how the Activity should be started. May be null if there are no options. See ActivityOptionsCompat for how to build the Bundle supplied here; there are no supported definitions for building it manually.
