Create 9patch with fully round sides

Question

I'm trying to create a drawable that looks like the KitKat toast bacground:

but I have no idea how to recreate the fully round sides, I always end up with a rectangle with rounded edges like this:

or the sides aren't really round:

Any idea on how to accomplish this?

Btw, just setting the color of the Toast doesn't work.

Answer 1

Android 9-patch shadow generator will help you achieve the desired 9patch, allowing you to customize the roundness of the sides to your liking.

"Fill & Outline" will also give you the ability to apply some color.
