Any listener that listen to events happening on your Views in your Activity should cease to receive message-notifications as soon as the Activity and its Window (and View hierarchy) are destroyed.
But if your code or some other code did a postDelayed on the main UI Looper, they will be dispatched, activity being destroyed or not. If your Runnable, that is posted by calling postDelayed is executed and is still referring to a destroyed Activity, you may get into trouble. To avoid this, (1) make your Runnable a separate static class and refer to the Activity by a WeakReference or (2) make your Runnable a field/member of your Activity and call removeCallbacks on that Runnable field/member in your implementation of onDestroy.
