In Activity, I register receiver in onCreate and unregister it onDestroy. It should works

  • 0

In Activity, I register receiver in onCreate and unregister it onDestroy. It should works fine if every onCreate is followed by onDestroy after the next onCreate. Otherwise, if onCreate is being called more than onDestroy, receiver is registered multiple time and the app mis-behaves.

So my questions are:

  1. Is that ok I register receiver in onCreate and unregister it in onDestroy?
  2. Is that onCreate is always followed by onDestroy before next onCreate?

    onDestroy is called when the activity is being destroyed. Or removed from the back stack, when ever the user doesn’t want it or there is no possible way to get back to it. When your activity wants to receive a broadcast that is fine to do it how you are. If there are no dialogs appearing or notifications or toasts appearing after you receive that should be fine also, if you want to be on the real safe side and only have one activity receiving at a time, and only while the activity is visible move these to onResume and onPause.

    You could probably some how unregister when another activity has been brought to the front and re-register after?
