    protected override void OnCreate (Bundle savedInstanceState)
        base.OnCreate (savedInstanceState);
        SetContentView (Resource.Layout.activity_main);
        if (savedInstanceState != null)
            mIsResolving = savedInstanceState.GetBoolean (KEY_IS_RESOLVING);
            mShouldResolve = savedInstanceState.GetBoolean (KEY_SHOULD_RESOLVE);

        FindViewById (Resource.Id.sign_in_button).SetOnClickListener (this);
        FindViewById (Resource.Id.sign_out_button).SetOnClickListener (this);
        FindViewById (Resource.Id.disconnect_button).SetOnClickListener (this);

        FindViewById<SignInButton> (Resource.Id.sign_in_button).SetSize (SignInButton.SizeWide);
        FindViewById (Resource.Id.sign_in_button).Enabled = false;

        mStatus = FindViewById<TextView> (Resource.Id.status);

        mGoogleApiClient = new GoogleApiClient.Builder (this)
            .AddConnectionCallbacks (this)
            .AddOnConnectionFailedListener (this)
            .AddApi (PlusClass.API)
            .AddScope (new Scope (Scopes.PlusLogin))

            .Build ();


public void OnConnectionFailed (ConnectionResult result)
        Log.Debug (TAG, "onConnectionFailed:" + result);

        if (!mIsResolving && mShouldResolve) {
            if (result.HasResolution) {
                try {
                    result.StartResolutionForResult (this, RC_SIGN_IN);
                    mIsResolving = true;
                } catch (IntentSender.SendIntentException e) {
                    Log.Error (TAG, "Could not resolve ConnectionResult.", e);
                    mIsResolving = false;
                    mGoogleApiClient.Connect ();
            } else {
                ShowErrorDialog (result);
        } else {
            UpdateUI (false);
