我试图写在Android 2.2的目标一个Twitter应用程序（使用一些样本code，我在网上找到并使用马尔科Gargenta的奥赖利文本）。我坚持这个问题下面在日志中。该人士$ ​​C $ C被首次随后日志。任何想法是怎么回事错在这里？也没有任何人有或者可以指向一个样本jtwitter code在Android上工作。

谢谢，拉维

解决方案

基本上JTwitter库已不在Android SDK的，因为它没有使用Swing的Java Swing类的调用。我不得不为JTwitter源并取出摆code我的应用程序工作。希望这有助于。

I am trying to write a twitter application on Android target 2.2 (using some sample code that I found on the net and using Marko Gargenta's O'Reilly text). I am stuck with the problem as in the log below. The source code is given first followed by the log. Any idea what's going wrong here ? Also does anyone have or can point to a sample jtwitter code working on Android.

Thanks, Ravi

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";
  }

}

Basically the JTwitter library has calls to Java swing classes that are not in the Android SDK as it does not use swing. I had to get the source for JTwitter and remove the swing code for my application to work. Hope this helps.
