main.xml文件错误The processing instruction target matching "[xX][mM][lL]" is not allowed

本文解决了一个在Android开发中遇到的XML文件解析错误:The processing instruction target matching [xX][mM][lL] is not allowed. 错误通常发生在XML文件头部,解决办法是在<?xml version=1.0 encoding=UTF-8?>前避免出现任何额外字符。

今天在编辑android main 文件时出了个错误:

The processing instruction target matching "[xX][mM][lL]" is not allowed.

这个异常解释为:xml文件不能被解析,一般出现这样的问题在于xml格式上,并且问题多出现在xml文件的头部。总结:<?xml version="1.0" encoding="UTF-8"?>前面不要有任何其他字符,如空格、回车、换行这些否则就会出现上面的异常。
