Я следую документации Google, чтобы внедрить функцию входа в Google+ в приложение.

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

Я следовал каждому шагу в соответствии с руководством, но застрял в ошибке, сгенерированной GoogleApiClient.Builder, я тщательно искал, но не получил результата. Пожалуйста, помогите мне разобраться. Спасибо.

Код ошибки:

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

Сообщение об ошибке :

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

    }

В этом коде, если я закомментирую .addConnectionCallbacks и .addOnConnectionFailedListener, то ошибка исчезнет. Ошибка, похоже, связана с их аргументами.

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