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

Question

我在尝试为Android Google登录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(下面)中,我在其中调用signOut()方法.

我已经查看了其他帖子中的解决方案,并试过它们无济于事:

java.lang.IllegalStateException:GoogleApiClient尚未连接

GoogleApiClient尚未连接异常 致命异常:java.lang.IllegalStateException GoogleApiClient尚未连接

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中(我要执行注销)

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

在我的App活动中扩展了Application(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!

Answer 1

你应该抛弃线程并创建第二个GoogleApiClient.根据这篇文章(/sf/answers/1763334821/),客户端不是一个沉重的对象,所以不妨避免混淆设计并使事情变得简单.即使你不沿着这条路走下去,你也应该删除它#setClient并#getClient编写代码,看看在断开单个活动时是否会出现同样的错误

Answer 2

我知道它很老的帖子已经回答了.

但是,错误的实际原因不是在单个或多个位置创建对象,而是在建立客户端对象时调用"enableAutoManage".

这里的API文档表明它会通过调用活动的onStart和onStop方法来自动进行生命周期管理.

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onStart of activity中)和apiObject.disconnect()(最好在onStop of activity中).

这对我有用,因此分享.
