KEYCODE_HOME and KEYCODE_POWER can't be trapped

[willheger]

Devices: Motorola Photon, Galaxy SIII, Le Pan Tablet, Galaxy Player

Problem: KEYCODE_HOME and KEYCODE_POWER key events don't emit, while _MENU, _BACK, _SEARCH, VOLUME, and others work perfectly.

Guess: the app probably pauses before the key event emits.

Alternative: Because HOME and POWER are generally the only way to pause the app on a default installation (because the app runs in stay awake mode by default), from a development perspective, the only need is to distinguish between 'how' the device was slept.

In other words, if it's not practical to trap a key event that triggers a shutdown, this alternative would probably satisfy most devs (which also has the benefit of allowing for other possible non-keypress pause sources):

    def on_pause(self, reason_for_pause):
         if reason_for_pause == Android.KEYCODE_HOME_REASON:
             self.perform_cleanup_A()

         if reason_for_pause == Android.KEYCODE_POWER_REASON:
             self.perform_cleanup_B()

         if reason_for_pause == Android.ANDROID_WANTS_TO_SLEEP_REASON:
             self.perform_cleanup_B()

        return True

So this is a very old request for a feature. But why does it matter? I honestly can not think of any reason that I would do on_pause differently for any given "KEYCODE" or because of a specific pause source. Can you explain why different sources matter to your app?
