I am working on a mock-up of a theme I would like to create in the future (after learning how specifically to implement it) and my design of the notification window seems to depart greatly from the rest of the themes I have seen posted here and elsewhere. This departure made me question whether my design is even within the limits of the Android environment.
Below is my mock-up of the notification window:
Is it possible to recreate the top arrow and the transparent space around the window?
Any further instructions would be much appreciated.
