google play services, resultcode 0 onactivityresult

Question

I've been trying to connect up to google play services without any success. I've been checking that all the keys and id's are correct.

But I'm not getting any traffic on my API manager. What on earth could be the problem?

    super.onCreate(savedInstanceState);

    Log.d(TAG, getSHA1CertFingerprint(this));

            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(Games.API).addScope(Games.SCOPE_GAMES)
            .build();

    textUpdate();
}

    super.onActivityResult(requestCode, resultCode, data);
    Log.d(TAG, "requestcode " + requestCode + " resultcode " + resultCode);

        mSignInClicked = false;
        mResolvingConnectionFailure = false;

Try checking the documents about "Troubleshooting Issues in Your Android Game" and "Debugging Your Android Games". This documents will help you debug and resolve the issue encountered in your game.

If you are unable to sign players into your game, first make sure that you have followed the instructions to create your client IDs and configure the games services. If you still encounter sign-in errors, check the following items to make sure that your game is set up correctly.

• Check your metadata tags
• Check your package name
• Check the certificate fingerprint
• Check that test accounts are enabled

For code implementation purposes, kindly check the samples by Google. This will show you the basic login, multiplayer, cloud saving and more.

Hope this helps.
