打开Android Studio报错，Unable to create Channel from class class

问题

打开Android Studio报错，报错信息如下：

Internal Error. Please report to https://code.google.com/p/android/issues

分析

根据两个Caused by，原因应该是由于未被承认的Windows Sockets导致Android Studio初始化的时候设置服务连接超时。

Caused by: io.netty.channel.ChannelException: Failed to set the server socket timeout.
Caused by: java.net.SocketException: Unrecognized Windows Sockets error: 10106: create

解决方法

1、使用管理员身份打开命令提示符工具

2、输入命令
netsh winsock reset

netsh winsock reset命令，作用是重置 Winsock 目录。如果一台机器上的Winsock协议配置有问题的话将会导致网络连接等问题，就需要用netsh winsock reset命令来重置Winsock目录借以恢复网络。这个命令可以重新初始化网络环境，以解决由于软件冲突、病毒原因造成的参数错误问题。 netsh是一个能够通过命令行操作几乎所有网络相关设置的接口，比如设置IP，DNS，网卡，无线网络等，Winsock是系统内部目录，Winsock是Windows网络编程接口，winsock工作在应用层，它提供与底层传输协议无关的高层数据传输编程接口，reset是对Winsock的重置操作。当执行完winsock的命令重启计算机后，需要重新配置IP。
3、重启电脑，再打开Android Studio
