如何從Android中的Facebook檢索我的位置和電話號碼？

Question

我是Android的新手。我已將Facebook與Android集成。 我檢索了id，名稱和個人資料圖片。 我想從Fb檢索我的電話號碼和位置。 我無法理解權限設置和所有權限。 我做了以下編碼。 我希望有人一步一步向我解釋該怎么做。 我的代碼如下：

MainActivity.class

session.openForRead(new Session.OpenRequest(MainActivity.this).setCallback(statusCallback).setPermissions(permissions));
    new Request(
       session,
       "/me?fields=location",
           null,
           HttpMethod.GET,                         
           new Request.Callback() {
                 public void onCompleted(Response response) {
                    // handle the result 
                    // f
                     Map<String, Object> responseMap = new HashMap<String, Object>();
                     GraphObject graphObject = response.getGraphObject();
                     responseMap = graphObject.asMap();
                     String location = responseMap.get("location").toString();
                     Log.i("location",""+location);
                 }
           }
        ).executeAsync();

   Session session = Session.getActiveSession();
    if (session.isOpened()) {
      Request.executeMeRequestAsync(session,new Request.GraphUserCallback() {
        @Override
        public void onCompleted(GraphUser user, Response response) {
           // TODO Auto-generated method stub
           if(user!=null){
                final String t1=user.getId();
                final String t2=user.getName();
           }
        }
    });

錯誤日志：

您無法獲取用戶的電話號碼。

要獲取位置，您需要：

• API調用： /me?fields=location - 演示
  
  
• 權限： user_location 在此處檢查如何使用android sdk請求其他權限。

獲取位置的代碼：

new Request(
   session,
   "/me?fields=location",
   null,
   HttpMethod.GET,
   new Request.Callback() {
     public void onCompleted(Response response) {
         /* handle the result */
     }
   }
).executeAsync();

查看用戶可以使用的所有字段： /{user-id}
