Android: Change delay before the phone is put to sleep while my app is running

This question sounds so easy I can't believe I can't find information on it (maybe I have the wrong key words in mind...)

I'm looking for a way to change the delay before the phone is put to sleep when my app is runnin开发者_StackOverflow中文版g.

I was using wake locks until now to prevent my app from being closed to frequently (its and opengl app and the loading time is a killer specially on slow phones). I don't like the idea of indefinitely leaving the phone on (mainly because it empties the battery fast to have a full opengl app running).

Is there a way then to change the delay before the phones goes to sleep to 2~3min ?

I would also like to add that I do not wish to change the settings of the phone (that is only the users decision)

edited to correct the term "application going to sleep" which was pointed out as being incorrect.

Create a Timer object and release() your wake lock in the timer task. I'm relatively sure you can release a lock in a worker thread, but worst case, you'd need to use runOnUiThread if I'm incorrect.

Be sure to handle the case when onPause() is called and cancel your timer in that case and release the lock immediately.

In general, I'm not a fan of wake locks, but if this is to make your boss happy, wake-lock away.

EDIT: Btw, the system setting for the UI timeout is accessible by apps: SCREEN_OFF_TIMEOUT in android.provider.Settings.System. But really, this is for private applications only, public applications have no business changing this value.
