Facebook SDK：在创建WebDialog.FeedDialogBuilder时没有“打开”会话状态

我在实现Facebook共享信息时遇到了这样一个奇怪的错误。我所做的所有阶段，因为他们在Facebook上的教程Facebook tutorial - share info Facebook SDK：在创建WebDialog.FeedDialogBuilder时没有“打开”会话状态

描述，但是当我试图创建实例WebDialog.feedDialog

private void publishFeedDialog() { 
 
     Bundle params = new Bundle(); 
 
     params.putString("name", getString(R.string.name_fb)); 
 
     params.putString("description", getString(R.string.description_fb)); 
 
     params.putString("link", getString(R.string.share_link_fb)); 
 
     params.putString("picture", getString(R.string.pictute_url_fb)); 
 
     
 
     Session session = Session.getActiveSession(); 
 
     
 
     Log.i(TAG, "session = " + session + " isOpen = " + session.isOpened() + " isClosed = " + session.isClosed()); 
 
     
 
     WebDialog feedDialog = (new WebDialog.FeedDialogBuilder(this, Session.getActiveSession(), params)) 
 
     \t \t .setOnCompleteListener(new OnCompleteListener() { 
 

 
       @Override 
 
       public void onComplete(Bundle values, FacebookException error) { 
 
        if (error == null) { 
 
        \t 
 
         // When the story is posted, echo the success and the post Id. 
 
         final String postId = values.getString("post_id"); 
 
         
 
         if (postId != null) { 
 
          Toast.makeText(MainActivity.this, "Posted story, id: " + postId, 
 
           Toast.LENGTH_SHORT).show(); 
 
         } else { 
 
          // User clicked the Cancel button 
 
          Toast.makeText(MainActivity.this, "Publish cancelled", 
 
           Toast.LENGTH_SHORT).show(); 
 
         } 
 
         
 
        } else if (error instanceof FacebookOperationCanceledException) { 
 
         // User clicked the "x" button 
 
         Toast.makeText(MainActivity.this, "Publish cancelled", Toast.LENGTH_SHORT).show(); 
 
         
 
        } else { 
 
         // Generic, ex: network error 
 
         Toast.makeText(MainActivity.this, "Error posting story", Toast.LENGTH_SHORT).show(); 
 
        } 
 
       } 
 

 
      }).build(); 
 
     
 
     feedDialog.show(); 
 
    }

我抓住FacebookException！

，我可以从日志中的主要麻烦明白的是Session.getActiveSession（那结果）不能为空，应打开，但我看到会议有状态只有创建！但是我做了Facebook教程所说的所有阶段！请帮助！

调查后，我解决我的问题：

1）创建feedDialog之前，我应该检查是否活动会话被打开，如果没有的话，我应该直接打开活动会话

\t if (Session.getActiveSession() == null || !Session.getActiveSession().isOpened()) { 
 
     Session.openActiveSession(MainActivity.this, true, callback); 
 
    } else { 
 
     publishFeedDialog(); 
 
    }

2）调用publishFeedDialog（）在Session.StatusCallback

private Session.StatusCallback callback = new Session.StatusCallback() { 
 
\t \t 
 
\t \t @Override 
 
\t \t public void call(Session session, SessionState state, Exception exception) { 
 
\t \t \t 
 
\t \t \t if (state.isOpened() && isFbShare) { 
 
\t \t \t \t publishFeedDialog(); 
 
\t \t \t } 
 
\t \t } 
 
\t };

谢谢。这节省了我的时间。从手机中卸载FB应用后，我开始出现这个问题。 – Narek 2014-10-15 14:32:51

谢谢@Alex Zezekalo。拯救了我的生命 – 2015-01-09 05:48:11

哦，我的上帝，为我完美工作。谢谢@Alex Zezekalo。 – sandeepmaaram 2015-02-16 11:48:57

除了上面接受的答案外，如果这是第一次用户体验流，用户需要登录才能创建会话。为了做到这一点，您需要将LoginActivity添加到您的AndroidManifest.xml中 -

<activity 
     android:name="com.facebook.LoginActivity" 
     android:label="@string/title_activity_facebook_login" > 
    </activity>
