connect refused
在使用android内置的模拟器访问本地机器上的资源时会报该错误
原因：模拟器把自己当成主机了，即，将127.0.0.1指向了自己
解决办法：android有个内置的ip：10.0.22，使用该ip来访问本地机器
将原url：http://localhost:8080/androidLoadTest/web/test.txt
改为：http://10.0.2.2:8080/androidLoadTest/web/test.txt

博客分类：
android手机做下载文件时，报了如下异常:
java.net.ConnectException: localhost/127.0.0.1:8080 -
Connection refused
报错在这一段代码
URL url = new URL("http://localhost:8080/mp3/resource.xml");&&&&
URLConnection urlconn = url.openConnection();&&&
原来模拟器默认把localhost或者127.0.0.1当做本身了
在网上查了下，在模拟器上可以用10.0.2.2代替127.0.0.1和localhost
另外如果是在局域网环境可以用 192.168.0.x或者192.168.1.x(根据具体配置)连接本机
