Could not find RippleDrawable

Question

I want to create a ripple dynamically in code.

Code:

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
      buyButton.setBack         


        

Answer 1

The issue is that you need to return a Drawable instead of a RippleDrawable in getPressedColorRippleDrawable. Otherwise, on pre-lollipop devices, you will get a VerifyError.

Answer 2

That code is indeed not being executed. The app crashes because you're receiving a java.lang.VerifyError. Try performing a Project → Clean if you're using Eclipse or Build → Rebuild project if you're using Android Studio.
