java - Android StAX Cursor Parser - 找不到方法 javax.xml.stream.XMLInputFactory.newInstance

Question

我正在使用 AsyncTask 从 i-net 下载和解析 XML 内容。 xml 的下载和解析发生在 doInBackground() 方法中。 “dalvikvm” 遇到问题 - 它找不到方法。

这是 LogCat 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}

有人可以帮我解释一下为什么找不到指定的方法吗？

谢谢!

关注Google , 我找到了 this和 this .

StAX 似乎在 Android 上不可用，但“等效”XmlPullParser可用。
