KeyguardManager km = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE); 
final KeyguardManager.KeyguardLock kl = km .newKeyguardLock("MyKeyguardLock"); 
kl.disableKeyguard(); 

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE); 
WakeLock wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK 
           | PowerManager.ACQUIRE_CAUSES_WAKEUP 
           | PowerManager.ON_AFTER_RELEASE, "MyWakeLock"); 
wakeLock.acquire();
