How to extend the Android settings menu?

Question

I want to extend the existing settings menu with one point (I want to add the option "infinite" to Settings -> Display -> Screen timeout). Does anybody know where I can find the sources for doing this? I think somewhere in frameworks/base/... ? Thank you!

Answer 1

Perhaps using a WakeLock is a decent alternative approach.

Short answer: you can't.

Long answer: you can't, because the Settings app does not provide this option. You would have to write your own Settings app.

If it's of any use, you can find the sources to the Settings app here:
