winterwell.jtwitter.TwitterException$Timeout -- 摘自书"Learning Android"

Question

当我运行第71页的代码时，eclipse显示了一些错误:

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

我不知道发生了什么，提前谢谢:)

PS:我在这里问过这个问题，但是没有回应

任何帮助都将是感激的:)

代码是:

Answer 1

超时异常表示远程服务器响应缓慢。它也可能表明您的网络连接有问题(尽管这通常会产生其他错误)。

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

Answer 2

我得到了同样的错误，当我更新jtwitter-yamba.jar时，它现在可以工作了。
