To unlock the keyguard.

add this permission <uses-permission android:name="android.permission.DISABLE_KEYGUARD" />

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main_layout);
    //  createWakeLocks();

            KeyguardManager kgm = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
            boolean isKeyguardUp = kgm.inKeyguardRestrictedInputMode();
            KeyguardLock kgl = kgm.newKeyguardLock("QuickPopup");

            if (isKeyguardUp) {
                kgl.disableKeyguard();
                isKeyguardUp = false;
            }
            getWindow().addFlags(
                    WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
            getWindow().addFlags(
                    WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
//          getWindow()
//                  .addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
            getWindow()
                    .addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
            //wakeDevice();
 }
