Another way to keep the screen lock on without having to request the permission in the manifiest is:

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

Are you doing your long loading process in the UI thread? Something doesn't seem right - if the process is so long that the screen lock timesout and your process ends, perhaps it needs to go in a background service.
