原因:java.lang.IllegalStateException:GoogleApiClient 尚未连接

Caused by: java.lang.IllegalStateException: GoogleApiClient is not connected yet

我在尝试为 Google 实施注销时收到此错误消息 为 Android 登录:

Caused by: java.lang.IllegalStateException: GoogleApiClient is not connected yet.

崩溃发生在 DrawerActivity.java(下图),我在这里调用了 signOut() 方法。

我查看了其他帖子中的解决方案并尝试过它们无济于事:

java.lang.IllegalStateException: GoogleApiClient is not connected yet

GoogleApiClient is not connected yet exception Fatal Exception: java.lang.IllegalStateException GoogleApiClient is not connected yet

MainActivity.java:

protected void onCreate(Bundle savedInstanceState) {
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .enableAutoManage(this, this)
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();
    //... other code for google sign in not shown
}

protected void onStart() {
    mGoogleApiClient.connect();
}

private void handleSignInResult(GoogleSignInResult result) {
    if (result.isSuccess()) {
        App.getInstance().setClient(mGoogleApiClient);
        //start DrawerActivity
    }
}

在DrawerActivity.java(我要执行注销的地方)

private void googleSignOut(){
    mGoogleApiClient = App.getInstance().getClient();
    Auth.GoogleSignInApi.signOut(mGoogleApiClient);
}

在我的扩展应用程序 activity 中(用于存储 GoogleApiClient)

public class App extends Application {

    private GoogleApiClient mGoogleApiClient;
    private static App mInstance;

    @Override
    public void onCreate() {
        super.onCreate();
        mInstance = this;
    }

    public static synchronized App getInstance() {
        return mInstance;
    }

    public void setClient(GoogleApiClient client){
        mGoogleApiClient = client;
    }

    public GoogleApiClient getClient(){
        return mGoogleApiClient;
    }
}

如有任何帮助,我们将不胜感激。谢谢!

您应该放弃线程并创建第二个 GoogleApiClient。根据此 post () 客户端不是一个沉重的对象,因此不妨避免混乱的设计并使事情变得简单。即使你不走这条路,你也应该去掉 #setClient#getClient 代码,看看在从单个 activity

断开连接时是否会出现相同的错误

我知道它很旧 post 并且已经回答了。

然而,真正的错误原因不是在一个或多个地方创建对象,而是在构建客户端对象时"enableAutoManage"调用。

API 文档 here 建议它将通过调用 activity.

的 onStart 和 onStop 方法自动进行生命周期管理

因此,如果您想在不同的活动中使用同一个对象,那么您应该避免调用 "enableAutoManage" 和调用 apiObject.connect(最好在 activity 的 onStart 中调用)和 apiObject.disconnect() (最好在 activity 的 onStop 中)。

这对我有用,因此分享。

删除这个:

.enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)

要在另一个Activity中制作一个退出按钮,例如:登录在Activity A中,退出在activity B中,则可以第二个使用这个 activity.

首先创建 OnStart 方法:

 @Override
protected void onStart() {
    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .build();
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();
    mGoogleApiClient.connect();
    super.onStart();
}

在你的按钮中搭配这个:

Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback(
    new ResultCallback<Status>() {
        @Override
        public void onResult(Status status) {
            // ...
            Toast.makeText(getApplicationContext(),"Logged Out",Toast.LENGTH_SHORT).show();
            Intent i=new Intent(getApplicationContext(),MainActivity.class);
            startActivity(i);
        }
    });

您可以查看是否已连接。

 if (mGoogleApiClient.isConnected()) {

          //your code
  }
