ArrayIndexOutOfBoundsException异常在Android的KXmlParser [英] ArrayIndexOutOfBoundsException in android's KXmlParser

问题描述

我在Android上做定期的XML解析，极少我得到这个例外，只有在特定的手机。一直没能得到这个问题的根源。没有任何人有一个想法是什么可能会导致什么呢？

  java.lang.ArrayIndexOutOfBoundsException：src.length = 8192 srcPos = 1 dst.length = 8192 dstPos = 0长度= -1
    在java.lang.System.arraycopy（本机方法）
    在org.kxml2.io.KXmlParser.fillBuffer（KXmlParser.java:1489）
    在org.kxml2.io.KXmlParser.skip（KXmlParser.java:1574）
    在org.kxml2.io.KXmlParser.parseStartTag（KXmlParser.java:1049）
    在org.kxml2.io.KXmlParser.next（KXmlParser.java:369）
    在org.kxml2.io.KXmlParser.next（KXmlParser.java:310）
 

解决方案

我有一个类似的异常。在我的情况下，XML已经下载并保存到SD。当我打开文件，我看到它切出中等句，因为它是。它看起来像有过在下载文件中的错误。删除文件和重新下载固定问题在这种情况下，但以prevent将来的相同类型的问题，我检查ArrayIndexOutOfBoundsException异常读取XML时，并假定文件损坏时，它捕获之一。

这显然只是一个创可贴解决一个定义模糊问题的时刻。如果我的数字多出，我会更新我的答案。

I am doing regular XML parsing on android, and very rarely I get this exception and only on particular phones. Haven't been able to get to the root of this issue. Does anybody have an idea what might be causing this?

    java.lang.ArrayIndexOutOfBoundsException: src.length=8192 srcPos=1 dst.length=8192 dstPos=0 length=-1

解决方案

I have a similar exception. In my case, the xml had been downloaded and saved to the SD. When I opened the file, I saw that it cut out "mid-sentence", as it were. It looked like there had been an error in downloading the file. Deleting the file and re-downloading fixed the issue in this instance, but to prevent future issues of the same type, I check for ArrayIndexOutOfBoundsException when reading an xml, and assume the file is corrupt when it catches one.

It's obviously just a bandaid solution to a vaguely defined problem at the moment. If I figure more out, I'll update my answer.
