Ich verfolge die Dokumentation von Google, um die Google+ Anmeldefunktion in einer App zu implementieren.

https://developers.google.com/+/mobile/android/getting-started

Ich habe jeden Schritt gemäß der Anleitung befolgt, bin aber in einem Fehler stecken geblieben, der vom GoogleApiClient.Builder generiert wurde. Ich habe gründlich gesucht, aber kein Ergebnis erzielt. Bitte helfen Sie mir, das zu klären. Danke.

Fehlercode:

    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this).addApi(Plus.API, null)
            .addScope(Plus.SCOPE_PLUS_LOGIN).build();

Fehlermeldung :

   The method addConnectionCallbacks(GoogleApiClient.ConnectionCallbacks) in the type 
   GoogleApiClient.Builder is not applicable for the arguments (MainActivity)

    }

Wenn ich in diesem Code .addConnectionCallbacks und .addOnConnectionFailedListener auskommentiere, verschwindet der Fehler. Der Fehler scheint mit ihren Argumenten zu zusammenhängen.

    mGoogleApiClient = new GoogleApiClient.Builder(this)
        //  .addConnectionCallbacks(this)
        //  .addOnConnectionFailedListener(this)
            .addApi(Plus.API, null)
            .addScope(Plus.SCOPE_PLUS_LOGIN).build();
