Answer 1

To make a button Sign Out in another Activity, for example: the login is in the Activity A and the sign out is in the activity B, then you can use this for the second activity.

First create the OnStart method:

 @Override
protected void onStart() {
    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .build();
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();
    mGoogleApiClient.connect();
    super.onStart();
}

After in your button collocate this:

Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback(
    new ResultCallback() {
        @Override
        public void onResult(Status status) {
            // ...
            Toast.makeText(getApplicationContext(),"Logged Out",Toast.LENGTH_SHORT).show();
            Intent i=new Intent(getApplicationContext(),MainActivity.class);
            startActivity(i);
        }
    });
