撤銷個人權限後更新會話

我試圖讓用戶通過複選框（Facebook SDK for Android）設置/撤消發佈權限。代碼如下。一切工作正常，除了撤銷負責檢查發佈權限的代碼失敗之後。撤銷個人權限後更新會話

我知道Session沒有辦法知道用戶是否在登錄後撤銷了任何權限。處理這種情況的正確方法是什麼？我是否必須手動查詢可用權限，或者有沒有一種方法可以使用基本權限無縫地重新創建會話？

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    ... 
    publishCheckbox = (CheckBox) view.findViewById(R.id.publishCheckbox); 
     publishCheckbox.setOnClickListener(new View.OnClickListener(){ 

      @Override 
      public void onClick(View v) { 
       CheckBox chb = (CheckBox) v; 
       if (chb.isChecked() && checkForPublishPermission() == false){ 
        requestPublishPermissions();        
       } 
       else{ 
        removePublishPermissions(); 
       } 

      } 

     }); 
    ... 
} 

private void requestPublishPermissions() { 
    Session session = Session.getActiveSession(); 
    if (session!= null && session.isOpened()){ 
     Session.NewPermissionsRequest newPermissionsRequest = new Session.NewPermissionsRequest(this, PERMISSIONS).setRequestCode(REAUTH_ACTIVITY_CODE); 
     newPermissionsRequest.setCallback(callback); 
     session.requestNewPublishPermissions(newPermissionsRequest); 
    }    
} 

private void removePublishPermissions() {  
    Request r = new Request(Session.getActiveSession(), PUBLISH_ACTIONS_PERMISSION_PATH, null, HttpMethod.DELETE); 
    r.setCallback(new Request.Callback() { 

     @Override 
     public void onCompleted(Response response) { 
      publishCheckbox.setEnabled(true);        
     } 
    }); 
    r.executeAsync(); 
    publishCheckbox.setEnabled(false); 
} 

private boolean checkForPublishPermission(){ 
    boolean result = false; 

    Session session = Session.getActiveSession(); 

    if (session == null || !session.isOpened()) { 
     result = false; 
    } 
    else{ 
     List<String> permissions = session.getPermissions(); 
     if (permissions.containsAll(PERMISSIONS)) { 
      result = true; 
     } 
    }  

    return(result); 
} 

private void onSessionStateChange(Session session, SessionState state, Exception exception) { 
    if (state.isOpened()) { 
     ... 
     publishCheckbox.setChecked(checkForPublishPermission()); 
     ... 
    } else if (state.isClosed()) {   
     ...        
    }  
}

我也在等待一個答案。如果用戶從他的在線帳戶中刪除整個應用程序會話將識別它並且您將註銷。但是，如果用戶只是刪除權限，會話將不會更新他的權限。 – StErMi

嗯，我結束了請求的用戶權限，每個我需要這樣的檢查，東西沿着這些線路時間：

private void checkForPublishPermission(){ 
    mPublishCheckbox.setEnabled(false); 
    Request r = new Request(Session.getActiveSession(), PUBLISH_ACTIONS_PERMISSION_PATH, null, HttpMethod.GET); 
    r.setCallback(new Request.Callback() { 

     @Override 
     public void onCompleted(Response response) { 
      if (response != null) { 
       GraphObject o = response.getGraphObject();    
        if (o != null){ 
         JSONArray data = o.getInnerJSONObject().optJSONArray("data");      
         mCanPublish = (data.optJSONObject(0).has("publish_actions"))?true:false;        
         mPublishCheckbox.setChecked(mCanPublish);              
        } 
      } 
      mPublishCheckbox.setEnabled(true); 
     } 
    }); 
    r.executeAsync(); 
}
