Я не могу скомпилировать этот код, потому что он говорит:

PlusClient.Builder не может быть разрешен для типа

в

mPlusClient = new PlusClient.Builder(this, this, this)
        .setVisibleActivities( "http://schemas.google.com/AddActivity",
        "http://schemas.google.com/BuyActivity").build();

также в onConnected()

Я получаю null для accountName

String accountName = mPlusClient.getAccountName();

Ответы

mClient = new GoogleApiClient.Builder(this)
        .addApi(Drive.API)
        .addScope(Drive.SCOPE_FILE)
        .addApi(Plus.API, plusOptions)
        .addScope(Plus.SCOPE_PLUS_LOGIN)
        .addConnectionCallbacks(this)
        .addOnConnectionFailedListener(this)
        .build();
