Fails when attempting to animate vector path attributes

[twyatt]

First and foremost, thanks for all your hard work on this library!

On Android API 14 devices, animating a vector group works beautifully but when attempting to animate vector path attributes (e.g. fillAlpha on path circlePath of circle.xml below) an exception is thrown:

The same project works when running on Android API 21+ devices.

I have the same problem.

[timrijckaert]

Same problem here. Any solutions?

[olegosipenko]

Confirm, it's falling when trying to animate path attributes. Though the Support Vectors from Support Library successfully animate these attributes, but have no ways to animate paths, this library successfully animates paths, but no path attributes

same problem , any solutions?

@mshenawy22 I don't believe this project is maintained anymore. Does the official AnimatedVectorDrawableCompat provide what you need?
