I have the same problem. I had to revert to an older Android Studio version.

The null is due to kapt won't be able to generate the necessary classes. I believe Gradle is also a part of the problem.
After messing around with various combination of those in Android Studio 4.2.1, I find that:

• AA 4.5.2 only work up to Gradle 4.8.1 and Android Gradle plugin 3.2.1.
• AA 4.8.0 only work up to Gradle 6.5 and Android Gradle plugin 4.1.0.

So for the latest Gradle 6.7.1 and Android Gradle plugin 4.2.1, it is still failing to generate the code.

@vxhviet it sounds like the library is deprecated because it cannot support the latest gradle versions, is it true?
Also, should we consider migrating to something else?
