Android library does not work with Java 8

Question

Problem

Since I switched to Java 8 in Android Studio 3.0 , the ShineButton library no longer works in my project.

---

java.lang.NoClassDefFoundError: Failed resolution of: Landroid/animation/Animator$AnimatorListener$$CC;

I get this error when used ShineButtonin my application in this part of the library for sure. Since this error occurred with my upgrade to Java 8, and I read about some similar error with Java 8, I am pretty sure that this is the factor that causes the problem.

purpose

I would like to have a solution that allows the library to work with Java 8 , because I like both the library and the functions that Java 8 provides. I'm not quite sure how to solve this problem, because I could not find any information about NoClassDefFoundErrorand about how closely it relates to Java 8.

Additional Information

I create my project in Android Studio 3.0 Canary 4 in Android O and I use the version 0.1.7of ShineButton.

Error while clicking ShineButtonwhile performing animation.

I already posted this on GitHub , but I did not see an answer to my own and even older issues. Recently, I also started releasing to the Android development team .
