I have a working Android app using:
- Google Maps (play-services-maps)
- Google Location, Activity Recognition, and Places (play-services-location)
- Google Analytics (play-services-analytics)
- Google Mobile Ads (play-services-ads)
I'm currently using version 8.3.0, everything works fine. I'd like to upgrade to the last version, 9.2.0. When I change the number in the gradle files, Android Studio is unable to find the APIs packages & classes (saying "package XXX does not exist" and "Cannot find symbol class YYY").
I currently have no google-services.json file, do I need it now? I tried without success, probably because I have several modules / submodules, and I don't know where the json file is needed or not.
The problem is that I need a package name to create the JSON file, and I have some library modules, without package name, using Google APIs.
If needed, here is the project structure:
