问题:

What does exactly adding apply plugin: 'com.google.gms.google-services' do? If I comment this, my app still will compile and run. More about adding Firebase to the project here.

回答1:

It reads resources out of your google-services.json file as described here. It also adds a compile dependency on firebase-core if not already present. That dependency will cause FirebaseInitProvider to get merged into your manifest, which is responsible for initializing a default FirebaseApp at app launch with the resources it read during the build phase.
