Facebook連接異常

Question

我想連接Facebook並在Facebook中獲取我的詳細信息，但是當我想獲取我的名字時，我得到一個帶有錯誤的JSONException：「」一個活動的訪問令牌必須用於查詢有關當前用戶「

我標誌着它的發生

非常感謝

這是我的班線：

public class MainActivity extends Activity { 

    private Button logInButton;

     super.onCreate(savedInstanceState); 

     this.requestWindowFeature(Window.FEATURE_NO_TITLE); 

     setContentView(R.layout.login); 

     facebook = new Facebook(APP_ID); 
     mAsyncRunner = new AsyncFacebookRunner(facebook); 

     final LayoutInflater inflater = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

     buttonLoginLogout=(Button) findViewById(R.id.facebooklog); 

     buttonLoginLogout.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
        loginToFacebook(); 
        getProfileInformation(); 
       } 
     }); 

    public void loginToFacebook() { 
     mPrefs = getPreferences(MODE_PRIVATE); 
     String access_token = mPrefs.getString("access_token", null); 
     long expires = mPrefs.getLong("access_expires", 0); 

     if (access_token != null) { 
      facebook.setAccessToken(access_token); 
     } 

     if (expires != 0) { 
      facebook.setAccessExpires(expires); 
     } 

     if (!facebook.isSessionValid()) { 
      facebook.authorize(this,

        new DialogListener() { 

         @Override

          SharedPreferences.Editor editor = mPrefs.edit(); 
          editor.putString("access_token",

          editor.putLong("access_expires",

         } 

         @Override 
         public void onFacebookError(FacebookError fberror) { 
          // Function to handle Facebook errors 

         } 

        }); 
     } 
    } 




    public void getProfileInformation() { 
     mAsyncRunner.request("me", new RequestListener() { 
      @Override 
      public void onComplete(String response, Object state) { 
       Log.d("Profile", response); 
       String json = response; 
       try { 
        JSONObject profile = new JSONObject(json); 
        // getting name of the user 
        final String name = profile.getString("name");  //this line i get an JSONException with error: 
                     //"An active access token must be used to query information about the current user " 
        // getting email of the user 
        final String email = profile.getString("email"); 

        runOnUiThread(new Runnable() { 

         @Override 
         public void run() { 
          Toast.makeText(getApplicationContext(), "Name: " + name + "\nEmail: " + email, Toast.LENGTH_LONG).show(); 
         } 

        }); 

       } catch (JSONException e) { 
        e.printStackTrace(); 
       } 
      } 

      @Override 
      public void onIOException(IOException e, Object state) { 
      } 

      @Override 
      public void onFileNotFoundException(FileNotFoundException e, 
        Object state) { 
      } 

      @Override 
      public void onMalformedURLException(MalformedURLException e, 
        Object state) { 
      } 

      @Override 
      public void onFacebookError(FacebookError e, Object state) { 
      } 
     }); 
    } 

} 

這裏是logcat的：

我推薦使用Facebook新的Android 3.0 Facebook庫。它有一個很好的教程和預建類來管理狀態和查詢。它比原來的庫更簡單和更清潔的
