How can I run emulator without GUI (headless Android)?
如何在没有 GUI（无头 Android）的情况下运行模拟器？
My requirement is to run the headless Androidon the emulator. Is it correct if I use ro.config.headless 1? Or disable zygote?

Android Emulator 28.1.8 now supports running the emulator in headless mode (emulator-headless): https://androidstudio.googleblog.com/2019/02/emulator-2818-canary.html

One of the options to achieve that is to stop zygoteservice when an emulator running. When stopping the zygoteprocess (aka app_process) all of the system services, that were forked from zygoteat system boot, shuts down. Only a few native system services will be running. The emulator's display should show the startup logo (or animation).
实现这一目标的方法之一是zygote在模拟器运行时停止服务。当停止zygote进程（又名app_process）时，所有zygote在系统启动时分叉的系统服务都会关闭。只有少数本地系统服务会运行。模拟器的显示屏应显示启动徽标（或动画）。
The steps for stopping zygoteare as follows:
停止步骤zygote如下：
adb shellsu(most of emulator images have/system/xbin/su)stop zygote
adb shellsu（大多数模拟器图像都有/system/xbin/su）stop zygote
After that you can explore how less services are running with service list. Critical for Android Runtime services will be stopped, e.g.
之后，您可以探索使用service list. Android 运行时的关键服务将被停止，例如
activity: [] // ActivityManager
package: [] // PackageManager
display: [] // DisplayManager
...
To start zygoteexecute:
开始zygote执行：
start zygote
start zygote
Note: with the @CommonsWare's solution you are still going to have zygoteand most of the Androidsystem services running.
注意：使用@CommonsWare 的解决方案，您仍然可以运行zygote大多数Android系统服务。
