图表Api无法从Android SDK SDK获取位置

Question

我在我的Android应用程序中使用Facebook SDK.我需要获取用户的所有信息.到现在为止,我可以获得名称ID电子邮件生日和用户的个人资料照片.我需要得到的最后一个是用户的位置或当前位置.我在下面使用此代码.

if(fb.isSessionValid()){
            button.setImageResource(R.drawable.logout_button);

            JSONObject obj = null;
            URL img = null;


             try {
                    String jsonUser = fb.request("me");
                    obj = Util.parseJson(jsonUser);
                    String id = obj.optString("id");
                    String name = obj.optString("name");
                    String bday = obj.optString("birthday");
                    String address = obj.optString("location");
                    String email = obj.optString("email");
                    ((TextView) findViewById(R.id.txt)).setText("Welcome! "+name);
                    ((TextView) findViewById(R.id.txtbday)).setText("Birthday: "+bday);
                    ((TextView) findViewById(R.id.txtaddress)).setText("Address: "+address);
                    ((TextView) findViewById(R.id.txtemail)).setText("Email: "+email);
                    img = new URL("http://graph.facebook.com/"+id+"/picture?type=normal");
                    Bitmap bmp = BitmapFactory.decodeStream(img.openConnection().getInputStream());
                    pic.setImageBitmap(bmp);

                } catch (FacebookError e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (JSONException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (MalformedURLException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }



        }else{
            button.setImageResource(R.drawable.login_button);
        }
    }

这是权限

fb.authorize(MainActivity.this,new String[] {"email", "user_location", "user_birthday","publish_stream"}, new DialogListener() {

                public void onFacebookError(FacebookError e) {
                    // TODO Auto-generated method stub
                    Toast.makeText(getApplicationContext(), ""+e, Toast.LENGTH_SHORT).show();   
                    e.printStackTrace();
                }

                public void onError(DialogError e) {
                    // TODO Auto-generated method stub
                    //Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_SHORT).show();      
                }

                public void onComplete(Bundle values) {
                    // TODO Auto-generated method stub
                    Editor editor = sp.edit();
                    editor.putString("access_token", fb.getAccessToken());
                    editor.putLong("access_expires", fb.getAccessExpires());
                    editor.commit();
                    updateButtonImage();
                }

                public void onCancel() {
                    // TODO Auto-generated method stub
                    Toast.makeText(getApplicationContext(), "Cancel", Toast.LENGTH_SHORT).show();   
                }
            });
        }

感谢谁能提供帮助.

Graph API Explorer工具是查看图API端点响应的好方法.只需user_location通过单击"获取访问令牌"并查看"/ me"的输出来请求正确的权限(例如).当我获得具有权限的访问令牌时,user_location我能够看到当前的

https://developers.facebook.com/tools/explorer/?method=GET&path=me

要获取当前位置,这是如何做到的:

String currentCity = obj.getJSONObject("location").getString("name");

使用较新的SDK,您可以通过图表API对象传递以下内容来获取位置详细信息

graphObject.getInnerJSONObject().getJSONObject("location").getString("id"))
