捕获GoogleApiClient.disconnect()回调

Question

我想捕获onDisconnected回调，但是onConnectionSuspended和onConnectionFailed都没有被调用。

public class mAct extends Activity implements
GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener {

//i'm using this:

protected void createClient() {
        if (gso == null) {
            gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestScopes(Drive.SCOPE_FILE)
            .requestScopes(Drive.SCOPE_APPFOLDER)// required for App Folder sample
            .requestEmail()
            .requestIdToken("MYKEY.apps.googleusercontent.com")
            .build();
        }
        if (mGoogleApiClient == null) {

            mGoogleApiClient = new GoogleApiClient.Builder(this)
                    .addApi(Plus.API)
                    .addApi(Drive.API)
                    .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
                    .addConnectionCallbacks(this)
                    .addOnConnectionFailedListener(this)
                    .build();
        }
    }
//this function calls `onConnected`
protected void connect() {
     if (mGoogleApiClient != null) {
         if (!mGoogleApiClient.isConnected() && !mGoogleApiClient.isConnecting()) {
             mGoogleApiClient.connect(GoogleApiClient.SIGN_IN_MODE_OPTIONAL);
         }
     }
    }

//but this is not
protected void disconnect() {
        if (mGoogleApiClient != null) {
                mGoogleApiClient.disconnect();
        }
    }
//to signout I use this

protected void signoutWorker() {
        if (mGoogleApiClient != null && mGoogleApiClient.isConnected()) {
            Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback(
                    new ResultCallback<Status>() {
                        @Override
                        public void onResult(Status status) {
                            //some setup and exit
                            disconnect();
                        }
                    });

//this works
    @Override
    public void onConnected(Bundle connectionHint) {
        Log.i(TAG, "onConnected()");
}

//this not works
@Override
    public void onConnectionSuspended(int cause) {
}
//this not works too
Override
    public void onConnectionFailed(ConnectionResult result) {
    }

}

据我所知，这个新的应用程序接口阻止了在调用mGoogleApiClient.disconnect时调用onConnectionFailed。我可以在disconnect()函数中使用回调吗？这是正常行为吗？

这就是：

 protected void disconnect() {
            if (mGoogleApiClient != null) {
                    mGoogleApiClient.disconnect();
                    myCallbackhere();//this callback
            }
        }

这两个方法都不是disconnect的回调方法。

@Override
public void onConnectionSuspended(int cause) {
}

当你的应用程序与谷歌Play服务包(不一定是互联网)断开连接时，会调用

onConnectionSuspended。

检查此stackoverflow link

@Override
public void onConnectionFailed(ConnectionResult result) {
}

当方法失败时，会调用

和onConnectionFailed，如DriveApi.newDriveContents等。

它支持检查错误或显示errorDialog，或在有解决方案时重试

检查此quickstart link

不幸的是，disconnect没有回调

但是googleDrive注销方法不在网络范围内。所以你不用担心在不知情的情况下注销

只需在disconnect()之后调用您的方法

尝试断开连接()，在没有wifi、数据的情况下进行连接
