How to prevent automatic screen lock on android by code?

Question

In my app there is a long loading process, and if the devices puts on the screen lock, my process stops for some reason.

How can i prevent the device from automatic screen lock?

Answer 1

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.
