java - 尝试通过 Google plus 实现登录的 Android 应用程序显示奇怪的系统错误

Question

我正在尝试在我的应用程序中通过 Google plus 登录，但是我遇到了一个非常奇怪的错误，我几乎在所有地方都搜索过这个错误，但没有运气。以下是我的代码，其中已完成实现。 logcat 显示系统错误 java.lang.IllegalArgumentException: GoogleApiClient parameter is required

主 Activity .java

// A magic number we will use to know that our sign-in error
// resolution activity has completed.

// The core Google+ client.
private PlusClient mPlusClient;


// A flag to stop multiple dialogues appearing for the user.
private boolean mResolveOnFail;

// We can store the connection result from a failed connect()
// attempt in order to make the application feel a bit more
// responsive for the user.

// case there is a delay in any of the dialogs being ready.

Answer 1

您永远不会将 mGoogleApiClient 设置为任何内容。

这取代了旧的 PlusClient/GamesClient/AppStateClient/等。客户。您创建一个 GoogleApiClient 并将其传递给任何 API 方法。

你有 mPlusClient = ... 你想用

替换它

mGoogleApiClient = new GoogleApiClient.Builder()
    .addApi(Plus.API, new Plus.PlusOptions.Builder()
        .addActivityTypes(
            "http://schemas.google.com/AddActivity",
            "http://schemas.google.com/BuyActivity")
        .build())
    .addConnectionCallbacks(this)
    .addOnConnectionFailedListener(this)
    .build()

然后删除 mPlusClient 并改用 mGoogleApiClient。
