I have developed a video player application. The app will keep playing videos (and repeat them). I want to handle it while its playing so I need the videos to be playing all the time but the android system makes the screen black automatically, lock the screen or put the system on sleep. I want to know how to avoid this from happen, i.e., my program should keep playing the video and the screen shouldn’t turn black. I have found some solutions on the Internet but still its not working, thanks for your help.

    Try using:

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

    or just:

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

    EDIT:
    according to this link : How do I prevent an Android device from going to sleep programmatically?. You should use:

    PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "My Tag");
wl.acquire();

..screen will stay on during this section..

wl.release();

    You also need to be sure you have the WAKE_LOCK permission set in your Manifest.
