Title: Android: Waking the screen, dismissing the keyguard Tags: android|android-wakelock|android-keyguard|android-windowflags Date: 2012-12-03 06:54:54 -0500 Author: Denevell

You can wake and keep wake the screen using the old:

 mPowerManager = (PowerManager) appContext.getSystemService(Context.POWER_SERVICE);
 mWakeLock = mPowerManager.newWakeLock((PowerManager.SCREEN_BRIGHT_WAKE_LOCK 
  | PowerManager.FULL_WAKE_LOCK 
  | PowerManager.ACQUIRE_CAUSES_WAKEUP), "TAG");
 if(mWakeLock.isHeld()) {
   mWakeLock.release();
 }
 mWakeLock.acquire();

And the WAKE_LOCK permission in your manifest. And you can disable the keyguard using the old:

 KeyguardManager keyguardManager = (KeyguardManager) appContext.getSystemService(Context.KEYGUARD_SERVICE); 
 KeyguardLock keyguardLock =  keyguardManager.newKeyguardLock("Tag");
 keyguardLock.disableKeyguard();

And, again, the KEYGUARD permission.

Or you can use the easier Window flags, which require no permissions since they are only applicable to one Window:

 activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
 activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
 activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
 activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
