android unlock screen intent?

Question

Is there an intent that is fired when a user unlocks their screen? I want my app to adjust the brightness when the screen turns on, but the problem im running into is that the screen on intent is fired on the lock screen and it does not adjust the display on that screen.

Answer 1

Yes, the ACTION_USER_PRESENT is broadcasted after the user unlocks:

http://developer.android.com/reference/android/content/Intent.html#ACTION_USER_PRESENT

Note that this is a protected broadcast and if the user is using a lock screen replacement such as WidgetLocker or NoLock the USER_PRESENT may not be sent or may be sent at the wrong time.
