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



我在尝试为Android版Google登录实现注销时收到此错误消息:

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

崩溃发生在 DrawerActivity.java(下图),我在其中调用 signOut() 方法。

我查看了其他帖子中的解决方案,并尝试了它们无济于事:

java.lang.IllegalStateException:GoogleApiClient尚未连接

GoogleApi客户端未连接但异常致命异常:java.lang.IllegalStateException GoogleApiClient 尚未连接

主活动.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
    }
}

在抽屉活动中.java(我想在其中执行注销)

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

在我的应用活动中,扩展了应用程序(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;
    }
}

任何帮助将不胜感激。谢谢!

你应该放弃线程,只创建一个GoogleApiClient。根据这篇文章(https://stackoverflow.com/a/25190497/608347),客户不是一个重物,所以不妨避免混乱的设计,让事情变得简单。即使您不走这条路,也应该删除该#setClient#getClient代码,并查看在断开与单个活动的连接时是否遇到相同的错误

我知道它的旧帖子并且已经回答了。

但是,错误的实际原因不是在单个或多个位置创建对象,而是在构建客户端对象时"启用自动管理"调用。

这里的 API 文档建议它通过调用活动的 onStart 和 onStop 方法自动执行生命周期管理。

因此,如果要在不同的活动中使用相同的对象,则应避免调用"enableAutoManage"并调用apiObject.connect(最好在活动的onStart 中)和apiObject.disconnect()(最好在活动的onStop中)。

这对我有用,因此分享。

要使按钮在其他活动中注销,例如:登录位于活动 A 中,注销位于活动 B 中,则可以将其用于第二个活动。

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();
}

在您的按钮中并置此按钮后:

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);
        }
    });

删除以下内容:

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

您可以检查是否已连接。

 if (mGoogleApiClient.isConnected()) {
          //your code
  }
