Where in the app does it logon?

NO WHERE! That’s the strangest thing.

I canceled the only line about login gpgs but it still logged in.

You deleted all login lines from your project?

Yes, even deleted including SonarFrameworks.h.

Pretty strange.

So basically this Helper only logs in when we call it, right?

Done. I use Visual Studio for modifying, but after I clean up project using Eclipse it stopped logging in automatically.

COOL        

Hmm… same happens to me here.

Starting the app → immediate login to google

(no code like signin oder something like that is prevented in my own code)

ok, we are looking into this, is this a major issue for you?

not major no. But will be when porting it to ios (dunno if ios users will like the immediate login screen) 

    // Whether to automatically try to sign in on onStart(). We only set this
    // to true when the sign-in process fails or the user explicitly signs out.
    // We set it back to false when the user initiates the sign in process.
    boolean mConnectOnStart = false;

    /*
     * Whether user has specifically requested that the sign-in process begin.
     * If mUserInitiatedSignIn is false, we're in the automatic sign-in attempt
     * that we try once the Activity is started -- if true, then the user has
     * already clicked a "Sign-In" button or something similar
     */
    boolean mUserInitiatedSignIn = false;

Found this in googleplaygameshelper.java from you.

Changed #mConnectOnStart to false. Now it does not login automatically anymore as explained in your document. Sorry I have missed that flag. Now a seperate login button can take the job.

Cheers

OK :D thats cool
