Answer 1

(App)-----depends----(library)

In my case I did not change any dependencies configuration nor i change the order. I had to copy a local pojo(model) jar file from the library module to App.

App is in kotlin library is in java

Its a bug, I should not have pojo.jar in app and library

Answer 2

Clean Project and Rebuild it This works for me

Answer 3

For me the problem was child module not using AndroidX Activity. I guess the class names clashed.

Added this to resolve:

implementation 'androidx.legacy:legacy-support-v4:1.0.0'
