背景

首先AS在显示连接设备窗口中显示device support，but ask only supports armeabi-v7a，之前可以正常debug；

其次，使用adb devices时报错如下：

➜  ～ adb devices -l
adb: failed to check server version: protocol fault (couldn't read status): Connection reset by peer

最后，adb kill-server也不行，报错如下：

➜  ～ adb kill-server
error: failed to read response from server

解决方法

通过kill pid关闭adb，而后启动adb即可

➜  ~ lsof -i :5037
