安装emulator
在Android Studio用户界面的Tools菜单中依次选择Android〉AVD Manager。
新建一个虚拟机，然后启动报错，
Cannot launch AVD in emulator.
Output:
emulator: ERROR: x86_64 emulation currently requires hardware acceleration!
Please ensure Intel HAXM is properly installed and usable.
CPU acceleration status: HAX kernel module is not installed!
日你个x， what the fuck.
这里也有人遇上了同样的问题：http://www.cnblogs.com/csulennon/p/4178404.html 不过他的容易搞定。
在Android SDK 里下载这个插件、安装即可：
可是安装的时候，遇上了新的错误：
重启，在主板的BIOS里把 VT-x 开启了就行了。
可是，卧槽，明明已经是开启的啊，这什么情况？ 开始怀疑是不是主板太老，，，，，
google了一下， 在stackoverflow 上发现了解决方法：

Just follows these steps: Go to Control Panel → Program and Feature. Click on Turn Window Features on and off. A window opens. Uncheck Hyper-V option and restart your system. Now, you can Start HAXM installation without any error.
好吧， 老衲在安装win10的时候开了Hyper-V， 就是你搞的。 去控制面板里把它卸载了，重启， 发现网卡列表里的虚拟网卡全部没了， O(∩_∩)O哈哈~ 没了就没了，太多看着烦。
继续安装HAXM。
刷刷，完成，启动虚拟机， 在console里看到：

卧槽， 你又是咋了， cmd -> sc query interhaxm 里已经能看到hax is running.....
居然这次是说内存要调整，，，太矫情了罢，
老衲就满足你吧~~~， 编辑 AVD， 把内存设置成768M， 启动， 哇咔咔~~
