模拟器版本Android emulator version 26.1.3.0 (build_id 4240222)

本文所述都是基于android8.1系统源码编译后的模拟器程序，不是android studio中的模拟器

部分参数说明：

-screen 触屏模式，可以为如下参数：touch, multi-touch, or no-touch

-accel 加速模式，可以为如下参数：on, off, auto

-writable-system 执行adb remount后system和vender分区可写

-skin 皮肤名称，如果是安卓系统源码，皮肤在development/tools/emulator/skins目录下

-wipe-data 清除用户数据

-shell 看着是可以显示系统的log了，其他区别不清楚

-cores 模拟器的cpu核心数

-gpu 设置硬件OpenGLES模拟模式，可选参数：on, off, auto

-memory 设置模拟器的物理内存大小，单位MB，有的时候设置比较大的值会导致模拟器无法启动

-show-kernel 显示内核消息

-no-boot-anim 禁止开机动画，加速模拟器启动速度，有的时候加上模拟器启动不了

-tcpdump <file> 将网络包抓到某个文件

-bootchart 允许-bootcharting，具体可以百度搜索一下bootchart

-selinux <disabled|permissive> 是否开启selinux

-dpi-device 设置设备的dpi

其他的配置文件

在生成的镜像目录中还有一个config.ini，也可以进行一些配置，具体参考自己机器上的文件进行配置

在我的机器上是out/target/product/generic_x86_64/config.ini这个文件
