I have been struggling with the The emulator process for AVD Pixel_2_API_30 was killed for a while now. I was trying to launch a Pixel 2 API 30 running android 11.0, I tried all the possible solutions but nothing seemed to work. I decided t use a different setup e.g. Pixel 2 API 28 running android 9.0, and it worked perfectly. I am not sure what causes the bug in the higher-level API or android version though... So my suggestion is to change the API and android version IF all of the other solutions didn't work.

我有同样的问题，问题是没有足够的空间在我的磁盘驱动器..你可以在“事件日志”层中看到关于你具体情况的详细信息，这一层通常位于Android studio的底部，它是我的输出日志:

"02:45 PM模拟器:模拟器:错误:没有足够的空间来创建用户数据分区。可用:3310.363281 MB /home/user/.android/avd/my_Nexus_5X_API_27。avd，需要7372.80万MB。

我只有7gb的空闲空间，所以只要在我的光盘里删除一些GB就可以了。

解决此错误的最佳5个选项，avd的模拟器进程被杀死

given option are checkpoints, check it out one by one.
Error Solution Option 1
Possiblity:
HAXM may not installed in System
HAXM - Hardware Accelerated Execution Manager
Solution:
SDK Manager > Check for HAXM installer
install it, if HAXM not installed
=======================================

Error Solution Option 2
Possiblity : 
Low disk size to load Emulator
Latest AVD with API level 30+ required approx 7 GB disk space
Solution:
Free space from disk where AVD is located

=======================================
Error Solution Option 3
Possiblity :
Configured AVD API may not available in SDK Manager
As an Example:
if Emulator with API level 30, same package of API 30 should be installed in SDK

Solution:
Install same version of SDK Platfrom from SDK manager,
as same as Emulator – AVD API

=======================================
Error Solution Option 4
Possiblity :
Configuration error in Old AVD 

Solution:
Recreate AVD with latest available update
Help > check for update, if component Android Emulator Update is available, install it
delete older AVD and create Fresh AVD

=======================================
Error Solution Option 5
Possiblity :
Embedded AVD not properly load with available image

Solution:
Launch AVD as independent component,
After success close it and lauch within Android Studio
Emulator inside Android Studio
=======================================

before apply all of above once restart you System, try it.

尽管这个问题是专门为Windows提出的，但我将为MacOS 11.4 Big Sur给出我的答案，因为这个线程是谷歌上搜索这个问题时的第一个热点，而且已经给出的答案都没有解决我的问题。

我在这里找到了问题的解决方案-出于保留的原因，我将重复详细的步骤:

打开终端，进入目录/Users/<username>/Library/Android/sdk/emulator/qemu/darwin-x86_64/ 创建一个名为entitled . XML的XML文件，内容如下:

<?xml version="1.0" encoding="UTF-8"?>
     <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" 
     "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
     <plist version="1.0">
     <dict>
         <key>com.apple.security.hypervisor</key>
         <true/>
     </dict>
     </plist>

退出模拟器

Codesign -s -——entitlement entitlement .xml——force qemu-system-x86_64

启动模拟器

您需要更新以下工具。

我尝试了这里的每一个答案，但没有一个成功，但最终当我在Android API 28的模拟器设备上运行它时，我得到了它的工作。我认为问题是模拟器设备不能运行Android API 30。
