退出AndroidStudio时卡死

最近经常遇到退出AndroidStudio的时候卡死，本身电脑配置不算低，而且打开时候不会卡，正常使用包括Build的时候也不会卡，就只有退出的时候会卡死。百度、google都没找到我这样的情况。。。
那只能自己解决了，先是尝试将gradle部署等放在本地，发现无效。。。修改VM内存大小，使用时速度是会变快一点，但还是没办法解决退出时卡死的问题。没办法，只好看日志了，可以通过Help->Show Log in Explorer 看到AndroidStudio的日志。
我们看下AndroidStudio在退出的时候究竟做了什么事情

原来是因为socks代理的原因，之前因为墙的原因设了本地socks代理，但是18+1大之后墙升级了，之前购买的vps不能用了。。。然后AndroidStudio退出的时候回去请求数据，socks代理返回的数据有问题，就阻塞到这里不动了。。。MDZZ
在File>Settings>Appearance&&Behavior>System Settings>HTTP Proxy中将代理更改为No Proxy，就可以正常退出了。
所以。。。。遇到bug要先看日志啊，可以省很多时间。。。。
