Turning on screen programmatically

Question

I would like to unlock screen and switching it on to show a popup on an event trigger. I am able to unlock the screen using

newKeyguardLock = km.newKeyguardL         


        

Answer 1

In your main activity's OnCreate() write following code:

((PowerManager)getSystemService(POWER_SERVICE)).newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "TAG").acquire();

It causes the device to wake up.

Do not forget disableKeyguard() to unlock the device...
