I have my main activity A and when the user presses a button i open another activity B. But when this happens B doesn't just appear on top of A: A disappears secure keyguard shows up B appears And when i get rid of B the same thing happens. This is annoying because there's a lot of flickering with no real purpose on the screen. Is there any way to achieve direct transition from A to B while keyguard is active without merging the 2 activities into 1? Here is what i'm doing in onCreate for both activities: getWindow().addFlags( WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD | WindowManager

Here is my code : menubuttonClosed = li.inflate(R.layout.menu_button, null); menubutton = (ImageButton) menubuttonClosed.findViewById(R.id.menubutton); params = new WindowManager.LayoutParams( WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.TYPE_SYSTEM_ALERT, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,// | WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, PixelFormat.TRANSLUCENT); params.x = 0; params.y = 0; params.gravity = Gravity.CENTER; menubutton.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch

I am trying to write an app that draws a custom mouse pointer. I currently have a service that creates a class that extends ViewGroup and uses the WindowManager system service to display it as a TYPE_SYSTEM_OVERLAY with the FLAG_LAYOUT_IN_SCREEN set. This almost works. On my tablet (Samsung Galaxy Tab 7.7) and in the emulator set to tablet mode, it is laid above everything except the bottom status bar (with the soft home, back keys and the notification area). In the emulator, there are no software buttons on screen, but it is laid on top of the notification bar. I've also tried the solution in

I'm trying to remove a layer added to WindowManager. But nothing happens when I call removeView(). Does anybody know how to remove it? My code looks like this. public class MainActivity extends Activity implements View.OnClickListener{ private WindowManager wm; private WindowManager.LayoutParams orientationLayout; private LinearLayout orientationChanger; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // init landscape things wm = (WindowManager) getApplicationContext().getSystemService(Service.WINDOW_SERVICE); orientationChanger = new

Update I was able to fix this, The problem was dialogs and related could be initiated from broadcast receiver but not recommended, as the activity running ends before the view. Trying to implement overlay like fb messenger, truecaller etc. public class IncomingCall extends BroadcastReceiver { private Context pcontext; private static final String TAG = "CustomBroadcastReceiver"; TelephonyManager telephony; CustomPhoneStateListener customPhoneListener ; @Override public void onReceive(Context context, Intent intent) { pcontext = context; Bundle extras = intent.getExtras(); if (extras != null) {
