最近經常遇到退出AndroidStudio的時候卡死，本身電腦配置不算低，而且開啟時候不會卡，正常使用包括Build的時候也不會卡，就只有退出的時候會卡死。百度、google都沒找到我這樣的情況。。。
那隻能自己解決了，先是嘗試將gradle部署等放在本地，發現無效。。。修改VM記憶體大小，使用時速度是會變快一點，但還是沒辦法解決退出時卡死的問題。沒辦法，只好看日誌了，可以通過Help->Show Log in Explorer 看到AndroidStudio的日誌。
我們看下AndroidStudio在退出的時候究竟做了什麼事情

原來是因為socks代理的原因，之前因為牆的原因設了本地socks代理，但是18+1大之後牆升級了，之前購買的vps不能用了。。。然後AndroidStudio退出的時候回去請求資料，socks代理返回的資料有問題，就阻塞到這裡不動了。。。MDZZ
在File>Settings>Appearance&&Behavior>System Settings>HTTP Proxy中將代理更改為No Proxy，就可以正常退出了。
所以。。。。遇到bug要先看日誌啊，可以省很多時間。。。。
