Answer 1

Base on my test switching build type or flavor, I noted that we should differentiate them as following:

For Debugging:
src/flavorDebug/google-services.json
src/flavor/debug/google-services.json
src/debug/flavor/google-services.json
If all flavors use only one firebase project with different app ids:
src/debug/google-services.json

For Releasing:
src/flavorRelease/google-services.json
src/flavor/release/google-services.json
src/release/flavor/google-services.json
If all flavors use only one firebase project with different app ids:
src/release/google-services.json

Without flavor should be as the following:
src/debug/google-services.json
src/release/google-services.json

With flavor but not separate build type:
src/flavor/google-services.json

For overall flavors and build types:
src/google-services.json

Note: flavor is referred to your flavor's name.
