android - winterwell.jtwitter.TwitterException$Timeout -- 来自书 "Learning Android"

Question

当我运行第 71 页的代码时，eclipse 向我显示了一些错误:

11-17 09:37:47.077: E/StatusActivity(370): winterwell.jtwitter.TwitterException$Timeout: http://yamba.marakana.com/api/statuses/update.json

我不知道发生了什么，先谢谢了:)

PS:我问过这个问题here , 但没有任何反应

任何帮助将不胜感激:)

        new PostToTwitter().execute(status);
        //twitter.setStatus(editText.getText().toString());
        Log.d(TAG, "onClicked");
    }
}

超时异常意味着远程服务器响应缓慢。它还可能表示您的网络连接存在问题(尽管这通常会产生其他错误)。

如果它经常发生，请尝试使用 IHttpClient.setTimeout() 方法增加超时设置。
