Should I manually close HandlerThreads created by my application when destroying the activity?

Question

My app is composed of a single Activity. In this activity, I\'m creating multiple HandlerThreads which run in a loop to do socket blocking operations.<

Answer 1

Yes, it would be a good idea to close it. Also make sure to remove your callbacks.

@Override
public void onDestroy() {
    super.onDestroy();
    handler.removeCallbacksAndMessages(null);
    handler.getLooper().quit();
}
