So either use a drawable image here. Or use a xml from drawable

问题 in numerous places, it is mentioned that app widgets should not get updated often, to minimize power consumption. But, let's consider that an application is doing something important (such as audio recording) for a short period of time, say 30min. In this case, is it acceptable to update the widget every second from a service? How can it be that this would consume so much power?

Is it something defined in AndroidManifest.xml ? 回答1: The very first thing I would check is that you allow Unknown Sources. Settings -> Applications -> Unknown Sources, be sure this box is checked before

My issue is that when I want to exit this activity and return back to previous, I should click twice the back button, in order to return back. If I click only once, the video starts playing once again, and only at the second attempt I'm allowed to exit the screen. Then I tried this: @Override public boolean onKeyDown(int keyCode, KeyEvent event)
