Oh dear. I didn't realize we couldn't use vectors. @lognaturel I assume this means we can't rely on vector drawables, and the solution is to use a bitmap instead?

@zestyping I'm really surprised by this and not immediately seeing the root cause. ContextCompat.getDrawable looks like it should handle all API levels.

Do you have a way of trying this out? Maybe https://developer.android.com/reference/android/support/v7/content/res/AppCompatResources.html#getDrawable(android.content.Context,%20int) does the trick?

It took some doing, but I was finally able to get it up in a 4.4 emulator and replicate this crash. Pushing a fix for your review now.
