java - Android 使用 jtwitter 抛出错误

Question

我正在尝试在 Android target 2.2 上编写一个 Twitter 应用程序(使用我在网上找到的一些示例代码并使用 Marko Gargenta 的 O'Reilly 文本)。我遇到了下面日志中的问题。首先给出源代码，然后给出日志。知道这里出了什么问题吗？还有人有或者可以指出在 Android 上运行的示例 jtwitter 代码吗？

谢谢，拉维

protected String doInBackground(String... statuses) {
  try {

         //Autho information
         /*OAuthSignpostClient oauthclient = new OAuthSignpostClient(cons_key, 
           cons_secret, access_token, access_secret);*/

         OAuthSignpostClient oauthclient = new OAuthSignpostClient(access_token, access_secret,"oob");

         //***POSTING TO TWITTER CURRENTLY DOES NOT WORK WITH THIS INTERFACE
         twitter = new Twitter(mytwitterusername, oauthclient);
         //twitter.setAPIRootUrl("http://learningandroid.status.net/api");

   //***POSTING TO TWITTER CURRENTLY DOES NOT WORK WITH THIS INTERFACE
   Log.i(Logtag, "Status currently is " + statuses[0]);

   Twitter.Status status = twitter.updateStatus(statuses[0]);
   //return status.text;
   return statuses[0];
  } catch (TwitterException e) {
   Log.e(Logtag, e.toString());
   e.printStackTrace();
   return "Failed to post to Twitter";
  }

}

Answer 1

基本上，JTwitter 库调用了 Android SDK 中没有的 Java swing 类，因为它不使用 swing。我必须获取 JTwitter 的源代码并删除 swing 代码才能使我的应用程序正常工作。希望这会有所帮助。
