我用的AsyncTask 下载并解析来自我网的XML内容。下载和XML解析在发生doInBackground（）方法。在dalvikvm遇到问题 - 它无法找到一个方法

I'm using AsyncTask to download and parse XML content from i-net. Downloading and parsing of the xml happens in doInBackground() method. The "dalvikvm" encounters a problem - it could not find a method.

下面就是 LogCat中的日志：

06-30 13:26:41.148: DEBUG/dalvikvm(507): GC freed 796 objects / 68088 bytes in 112ms

06-30 13:27:00.300: WARN/ActivityManager(52): Activity destroy timeout for HistoryRecord{43814048 com.news.reader/.SplashScreen}

能有人来帮我解释一下为什么找不到指定的方法？

Could some one to help me and explain why it couldn't find the specified method?

谢谢！

推荐答案

在看谷歌，我发现这和这个。

看起来像的StAX是不是可以在Android，而是一个等价物的 XmlPullParser 是可用的。

Looks like StAX is not available on Android, but that an "equivalent" XmlPullParser is available.
