Answer 1

if your application apiLevel >= 19, don't use

WindowManager.LayoutParams.TYPE_PHONE or WindowManager.LayoutParams.TYPE_SYSTEM_ALERT

you can use

LayoutParams.TYPE_TOAST

or

TYPE_APPLICATION_PANEL

now my code for LayoutParams is like,

WindowManager.LayoutParams params = new WindowManager.LayoutParams(
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.TYPE_TOAST,
            WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
            PixelFormat.TRANSLUCENT);
