Answer 1

After lot of searching for above problem, I found solution my self. Here it is how I made view to be on top of everything inside device and also making it touchable which was not possible with TYPE_SYSTEM_OVERLAY.

WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                        WindowManager.LayoutParams.MATCH_PARENT,
                        WindowManager.LayoutParams.WRAP_CONTENT,
                        WindowManager.LayoutParams.TYPE_SYSTEM_ERROR,
                        WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
                                WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
                        PixelFormat.TRANSPARENT);

params.gravity = Gravity.TOP | Gravity.CENTER_HORIZONTAL;
WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
wm.addView(view, params);
