Difference between Wakelock and FLAG_KEEP_SCREEN_ON?

Question

Keeping the screen awake can be accomplished by using a wakelock by

mWakeLock = mPowerManager.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK, 
                     


        

Answer 1

Wakelock is vague, since it has many different options. The flag FLAG_KEEP_SCREEN_ON only does that.

| Flag Value              | CPU | Screen | Keyboard |
-----------------------------------------------------
| PARTIAL_WAKE_LOCK       | On* | Off    | Off      |
| SCREEN_DIM_WAKE_LOCK    | On  | Dim    | Off      |
| SCREEN_BRIGHT_WAKE_LOCK | On  | Bright | Off      |
| FULL_WAKE_LOCK          | On  | Bright | Bright   |
