After phone lock flashlight app stop flashing

I tried a code below but it just prevents screen to be slept.

   Window window = getWindow();
    WindowManager.LayoutParams params = window.getAttributes();
    window.setAttributes(params);
    window.addFlags(
         WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON

            | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);

What should I use to prevent flashlight stop working during lock. I search though and got above idea. any help would be appreciated. Thanks.
