使用

初始化您的api客户端

// Initializing google plus api client
        mGoogleApiClient = new GoogleApiClient.Builder(this)
        .addConnectionCallbacks(this)
        .addOnConnectionFailedListener(this)
        .addApi(Plus.API, Plus.PlusOptions.builder().build())
        .addScope(Plus.SCOPE_PLUS_LOGIN).build();

使用addApi(Plus.API, Plus.PlusOptions.builder().build()) 而不是addOnConnectionFailedListener(this).addApi(Plus.API, null)

不要使用null，请使用 Plus.PlusOptions.builder（）。build（）

这肯定会解决您的问题
