嗨，我正在尝试在我的 android 应用程序中获取 facebook 用户数据。这是我请求用户信息的方法：
//Requests the user's info
private void makeMeRequest(final Session session){
//Request request = Request.newMeRequest(session, new Request.GraphUserCallback(){
Request request = Request.newGraphPathRequest(session, "me/feed", new Request.Callback(){
@Override
//public void onCompleted(GraphUser user, Response response){
public void onCompleted(Response response){
if(session == Session.getActiveSession()){
if(user != null){
GraphObjectList<GraphObject> test = response.getGraphObjectList();
//JSONArray test2 = test.getInnerJSONArray();
}
if(response.getError() != null){
}
}
});
request.executeAsync();
}
这是我在 LogCat 中得到的响应：

所以我很确定我会收到回复，但是当我在我的方法中取消注释该行时，我会得到一个NullPointerException. 为什么它给我这个？我也打印了我的会话信息，这是输出：
03-15 20:53:20.186: I/SESSION(321): {Session state:OPENED, token:{AccessToken token:ACCESS_TOKEN_REMOVED permissions:[read_stream, user_birthday, user_likes, user_status, basic_info]}, appId:222555791218743}
这个错误是因为ACCESS_TOKEN_REMOVED零件吗？如果是我怎么能正确登录？
谢谢
