Try SYSTEM_ALERT_WINDOW
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
Create a service and in the service,
WindowManager mWindowManager =
(WindowManager)getSystemService(WINDOW_SERVICE);
LayoutInflater inflater =
(LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mTopView = (ViewGroup) inflater.inflate(R.layout.top_view, null);
WindowManager.LayoutParams mWmlp = new
WindowManager.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT);
mWmlp.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH;
mWmlp.type = WindowManager.LayoutParams.TYPE_SYSTEM_ALERT;
mWmlp.width = 300;
mWmlp.height = 200;
mWmlp.format = PixelFormat.TRANSPARENT;
mWmlp.x = 0;
mWmlp.y = 0; //will be in the center of screen
mWindowManager.addView(mTopView, mWmlp);
