如何使用新的Android SDK发送FQL查询

我一直在搜索 developers.facebook网站,寻找一种使用新SDK并发送FQL查询的方法,但似乎所有内容都发生了变化,文档正在谈论各种其他方式来请求我或朋友,但没有具体的信息那些使用我的应用程序的朋友也是如此？

所以我写了一个很好的FQL查询

select uid,name,pic_square,is_app_user from user where uid in (select uid2 from friend where uid1 = me())

现在,我所要做的就是运行它.

由于对返回朋友列表似乎很好的唯一请求是Request.executeMyFriendsRequestAsync和Request.newMyFriendsRequest,我认为他们是我的朋友,但是两者都不允许微调FQL查询.

如何发送查询并返回一个朋友列表或至少一个JSONArray？

Hackbook – FQL Query教程正在使用旧版本的SDK,我不知道该怎么做.

更新：

我添加了这些代码行,它会让我创建这个查询：

public void onCreate(Bundle savedInstanceState) {
    // SOME CODE
    this.openSession();
}

protected void onSessionStateChange(SessionState state,Exception exception) {
    if (state.isOpened()) {
        Session activeSession = getSession().getActiveSession();
        facebook.setAccesstoken(activeSession.getAccesstoken());
        facebook.setAccessExpires(activeSession.getExpirationDate().getTime());

        Request req = Request.newMyFriendsRequest(activeSession,new GraphUserListCallback() {

            @Override
            public void onCompleted(List<GraphUser> users,Response response) {
                System.out.println(response.toString());

            }
        });
        Bundle params = new Bundle();
        params.putString("method","fql.query");
        params.putString("query","select uid,is_app_user " + "from user where uid in "
                + "(select uid2 from friend where uid1 = me())");
        req.setParameters(params);
        Request.executeBatchAsync(req);

    }
}

我这样做,认为它会编辑请求并添加我想要的信息,但我有这个错误：

解决方法

你会做这样的事情：

String fqlQuery = "select uid,is_app_user from user where uid in (select uid2 from friend where uid1 = me())";
Bundle params = new Bundle();
params.putString("q",fqlQuery);

Session session = Session.getActiveSession();
Request request = new Request(session,"/fql",params,HttpMethod.GET,new Request.Callback(){ 
        public void onCompleted(Response response) {
        Log.i(TAG,"Got results: " + response.toString());
    }
});
Request.executeBatchAsync(request);

您基本上将一个Graph API请求发送到“/ fql”端点,并将查询传递给“q”参数.
