Answer 1

If you're developing your own ROM or you have a rooted phone (it's need to be checked which user is able to do this) then you should have a look to the PowerManager.goToSleep functionality. Here is a discussion about this function in the Google Groups. And here you can read about this particular permission.

This is what i think you are looking for. Don't forget to include following permission.

android.permission.DEVICE_POWER

Welcome to Stack Overflow! Do you know that is a Question & Answer based forum? Do you think yours is an answer? You should provide some examples, or at least specify something more than displaying a constant and a link to an API. – Coliseum

Answer 3

This functionality has been removed since API level 21: https://developer.android.com/sdk/api_diff/21/changes/android.os.PowerManager.html

Like Yury also mentioned, before you were able to call powerManager.goToSleep(time), but you would have needed a rooted device or app would have needed to be signed as a system app to acquire the relevant rights.
