Answer 1

I think the directory in bin change from

com/XXX/XXX

to

classes/com/XXX.

You can clean your project and solve it.

Answer 2

Change implementation fileTree(include: ['.jar'], dir: 'libs') to provided fileTree(include: ['.jar'], dir: 'libs') in your app gradle.build> dependencies.

Make sure it has changed in your Module Settings> Dependencies {include=[*jar] dir=libs} too. It must have a scope of Provided next to it and not Implementation.
