Answer 1

first of all, did you changed package name only in Manifest? note that it could be different to applicationId - so you can only change it and leave app package as it was.

RCA: probably OS you are using to build is case-insensitive but java compiler is - that's reason why it can't find classes. Bindings are generated alongside other generated classes (for example dagger 2 classes generated by annotation processor), each generator creates own files within folder structure that reflects class package BUT if packages differ only with big/small letters, second generator will use same folder with wrong name. The reason is if OS is case-insensitive it assumes that folder already exist but java compiler not.

Other solution (except leaving app package as it is) is to :

• rename all packages in app to other that differ to app package or to use OS that is case-sensitive (macOS could be formatter this way or linux)
