This is no bugreport, more a question.

I started editing the google sign in plugin for android and figured out several problem, I would like to fix.

In order to do so, I would like to know what the getToken method is used for. According to the rest of the implementation, you can get the token out of the GoogleSignInAccount after a successful login. IMHO this method is not necessary, but I guess there's a reason for you to have it in there.

If not, I would like to remove it, since it's not really required and the dependency required (guava) is a method limit killer, since guava comes with about 15k methods

If it is needed for some reason, I created an alternative implementation without the guava dependency using android build in tools. See the PR mentioned below
