If you are having this issue on Android L (5.0), I have noticed that GradientDrawable does not accept the "%" suffix. So instead, I have used the "%p" suffix, and it works. Also, I needed to change my absurdly high value (80000%) with a normal value (80%p), and now it looks proper.

So, I have created a "drawable-v21" folder (from which Android L will take its drawables), copied my shape xml which contains the gradient and changed this line:

android:gradientRadius="80000%"

with this

android:gradientRadius="80%p"

Answer 3

In my case i added android:gradientRadius="30dp".

That dp at the end was trowing the same exception on some devices.

Leave it android:gradientRadius="30" or use the @radu122 's answer
