Android上的Facebook OAuth

Question

每次我在模擬器上測試我的應用程序。 「AppName發生錯誤，請稍後再試。」我在清單.XML中啓用了互聯網訪問。

這是我到目前爲止有：

package com.xxxxxx; 

import android.app.Activity; 
import android.content.Intent; 
import android.os.Bundle; 
import android.util.Log; 
import android.widget.TextView; 

import com.facebook.android.DialogError; 
import com.facebook.android.Facebook; 
import com.facebook.android.Facebook.DialogListener; 
import com.facebook.android.FacebookError; 
import com.facebook.android.Util; 

public class LunchtimeActivity extends Activity { 

    Facebook facebook = new Facebook("xxxxxxxxxxxxxx"); 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     //setContentView(R.layout.main); 

     facebook.authorize(this, new String [] {"user_location", "friend_location", "user_events", "friends_events"}, new DialogListener() { 
      @Override 
      public void onComplete(Bundle values) {} 

      @Override 
      public void onFacebookError(FacebookError error) {} 

      @Override 
      public void onError(DialogError e) {} 

      @Override 
      public void onCancel() {} 
     }); 

     Bundle parameters = new Bundle(); 
     parameters.putString("fields", "id,name"); 

     try { 
      String response = facebook.request("me/friends", parameters); 

      JSONObject json = Util.parseJson(response); 

      JSONArray data = json.getJSONArray("data"); 

      for (int i = 0; i < data.length(); i++) 
      { 
       JSONObject friend = data.getJSONObject(i); 

       String id = friend.getString("id"); 
       String name = friend.getString("name"); 
       Log.v("JSON", id); 
       Log.v("JSON", name); 
      } 
     } 
     catch (Exception e) {} 
     catch (FacebookError f) {} 

     TextView tv = new TextView(this); 
     tv.setText("Hello, Android"); 
     setContentView(tv); 
    } 

    @Override 
    public void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 

     facebook.authorizeCallback(requestCode, resultCode, data); 
    } 
} 

logcat的輸出：

...

Eclipse控制檯輸出：

我從字面上絕對t使用Facebook本身爲Android提供的Facebook SDK，我無法使其工作。有任何想法嗎？

Answer 1

您使用的friend_location代替friends_location

檢查logcat中的最後幾行：

05-01 02:21:01.601: DEBUG/Facebook-WebView(234): Webview loading URL: fbconnect://success/?error=invalid_scope&error_description=Unsupported+scope%3A+%27friend_location...

順便說一句，這是至少一些日誌輸出增加public void onFacebookError(FacebookError error) {}和catch (Exception e) {} catch (FacebookError f) {}一個好主意。這將節省你（和我們）很多時間:)
