FacebookSDK Request.newMeRequest从来没有被称为

问题描述

我有一个问题 - 我正在开发与Facebook登录的应用程序，我也需要得到用户的数据，有些原因我不能收到Request.newMeRequest这个数据，因为它的onCompleted方法不会被调用。我在logcat中看到的只有登录/退出的消息。我做错了什么？

下面是我的code：

 私人Session.StatusCallback statusCallback =新Session.StatusCallback（）{
    @覆盖
    公共无效呼叫（会话的会话，SessionState会状态，例外的例外）{
        onSessionStateChange（会话，状态除外）;
    }
};

私人无效onSessionStateChange（会话的会话，SessionState会状态，例外的例外）{
    如果（state.isOpened（））{
        Log.i（QWE，已登录......）;
        Request.newMeRequest（会话，新Request.GraphUserCallback（）{
            @覆盖
            公共无效onCompleted（GraphUser用户，响应响应）{
                Log.i（QWE，onCompleted）;
                如果（用户！= NULL）{
                    Log.i（QWE，用户为+ user.getUsername（））;
                }
            }
        }）;
    }否则如果（state.isClosed（））{
        Log.i（QWE，注销...）;
    }
}
 

解决方案

这里的问题是，你已经创建了一个请求，但你不能在它调用executeAsync，因此请求从未。尝试：

  Request.newMeRequest（会话，新Request.GraphUserCallback（）{
    @覆盖
    公共无效onCompleted（GraphUser用户，响应响应）{
        Log.i（QWE，onCompleted）;
        如果（用户！= NULL）{
            Log.i（QWE，用户为+ user.getUsername（））;
        }
    }
}）executeAsync（）。 //＆LT; --- CHANGE IS HERE
 

I've got a problem - I'm developing an app with facebook login and also I need to get User data, for somewhat reason I cant receive this data in Request.newMeRequest, because its onCompleted method never been called. I see in logcat only Logged in/out messages. What I'm doing wrong?

Here is my code:

private Session.StatusCallback statusCallback = new Session.StatusCallback() {
    @Override
    public void call(Session session, SessionState state, Exception exception) {
        onSessionStateChange(session, state, exception);
    }
};

private void onSessionStateChange(Session session, SessionState state, Exception exception) {
    if (state.isOpened()) {
        Log.i("QWE", "Logged in...");
        Request.newMeRequest(session, new Request.GraphUserCallback() {
            @Override
            public void onCompleted(GraphUser user, Response response) {
                Log.i("QWE","onCompleted");
                if (user != null) {
                    Log.i("QWE", "User is "+ user.getUsername());
                }
            }
        });
    } else if (state.isClosed()) {
        Log.i("QWE", "Logged out...");
    }
}

解决方案

The problem here is that you've created a request, but you're not calling executeAsync on it, so the request is never made. Try:

Request.newMeRequest(session, new Request.GraphUserCallback() {
    @Override
    public void onCompleted(GraphUser user, Response response) {
        Log.i("QWE","onCompleted");
        if (user != null) {
            Log.i("QWE", "User is "+ user.getUsername());
        }
    }
}).executeAsync();  // <--- CHANGE IS HERE
