android - Facebook SDK : not "opened" session state while creating WebDialog. FeedDialogBu​​ilder

Question

我在实现 Facebook 共享信息时遇到了这样一个奇怪的错误。我按照 Facebook 教程中的描述制作了所有阶段 Facebook tutorial - share info

但是当我尝试创建 WebDialog.feedDialog 的示例时

    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))
        		.setOnCompleteListener(new OnCompleteListener() {

                @Override
                public void onComplete(Bundle values, FacebookException error) {
                    if (error == null) {
                    	
                        // 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();
    }

我捕获了 FacebookException!

正如我从日志中了解到的，主要问题是 Session.getActiveSession() 的结果不应该为 null 并且应该打开，但正如我所看到的 session 有状态仅创建!但我按照 Facebook 教程所说的完成了所有阶段!请帮忙!

Answer 1

经过调查我解决了我的问题:

1) 在创建feedDialog之前我应该​​检查Active Session是否打开，如果没有那么我应该直接打开Active Session

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

2) 并在 Session.StatusCallback 中调用 publishFeedDialog()

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