Hello,

When using the circular spinner in our app we get this exception on release builds only (minified) :
It works fine in debug.

I am starting to loose faith in Android animated vector drawables ;)

Our build is using Gradle 3.0 but we deactivated aapt2.

Don't lose faith in AVDs! Lose faith in aapt2 instead. :P

To be clear, does this happen in this sample app? Or does it happen in some other repo you have?

[alexjlockwood]

Are you still seeing this issue?

@alexjlockwood thanks for the follow up. The crash happened in our app on release build (proguard/shrink). Since then we removed the avd_progress_indeterminate_circular and used a circular ProgressBar.
