I used:
getWindow().addFlags(android.view.WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
How do I resume to Default state (no-keep-on)?

I've created these kotlin extensions:
fun Activity.keepScreenOn(rootView: View? = null) {
window.addFlags(android.view.WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON)
rootView?.keepScreenOn = true
}
fun Activity.clearScreenOn() {
window.clearFlags(android.view.WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON)
}
Then onCreate
you can call keepScreenOn()
and onDestroy
clearScreenOn()

Directly from documentation:
Note: You don't need to clear the FLAG_KEEP_SCREEN_ON flag unless you no longer want the screen to stay on in your running application (for example, if you want the screen to time out after a certain period of inactivity). The window manager takes care of ensuring that the right things happen when the app goes into the background or returns to the foreground. But if you want to explicitly clear the flag and thereby allow the screen to turn off again, use clearFlags(): getWindow().clearFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON).

Another approach
getWindow().setFlags(this.getWindow().getFlags() & ~WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
and you can also set android:keepScreenOn="true"
in the root View in xml.

If you instead set a flag android:keepScreenOn="true" (documentation) only on the views that need to keep the screen on, you wouldn't need to reset the flag manually.
