XML or text declaration not at start of entity异常的原因_移动开发_编程开发_程序员俱乐部

今天在做XML解析的时候，总是给我报

XML Parsing Error: XML or text declaration not at start of entity

?

的错误，后来查了下讲大概意思是android中解析的时候xml文件格式问题。

?

在文件的最前端 即<?xml version="1.0" encoding="UTF-8"?>前面不能有空格。

?

修改即好。

xml

  <?xml version="1.0" encoding="UTF-8" ?> 
- <msg>
