如果你的用户名不是ascii/有空格，那么这可能会有帮助，因为我尝试了这里所有的解决方案，不能解决这个问题:

注:我在这个视频中找到了这个解决方案，是一个叫“tatachka”的用户建议的，这是她的评论(她很友好地让我分享在这里)。

For example, I had this path c:\Users\Таня.android\avd\Nexus_One_API_24.avd My name in Windows is Таня, written in Cyrillic in windows encoding (cp1251). I changed the path to e:\Distribu\AVD.android\avd\Nexus_One_API_24.avd I moved files from disk C there and edited Nexus_One_API_24.ini changing the path in it and everything worked. How to change the folder path: My computer -> properties -> advanced system parameters -> environment variables - > lower 'New...' button: variable name: ANDROID_SDK_HOME variable value: e:\Distribu\AVD (in my case) After the reboot, a new folder(.android) appears in the folder e:\Distribu\AVD containing the 'avd' folder

编辑:为了澄清，这里的想法是您不希望路径具有非ascii字符。我把它移动到C:\programs_that_cant_read_hebrew(并执行了其他步骤)，它工作得很好。

编辑:在注释后将“英文”更改为“ascii/空格”

这个错误非常普遍，这种症状可能是由于一百万个完全不同的问题中的任何一个造成的。 你要做的是找到更多关于正在发生的事情的信息，这样你就不会看起来像一只瞎鸡在啄食令人作呕的石头。 因此，让我们得到调试步骤:

first thing is to find the logs of Android studio. In doubt, stackoverflow already has a section to help you How to find the logs on android studio?. The text file should be named: "idea.log". You can open it with notepad, but only open it after android studio is closed (in windows 10). There will be a lot of events inside. Search by "manager.EmulatorProcessHandler" and the last date that you had the error. A good trick to facilitate your life, after having found the log file, is to close Android studio: delete the log file; reopen android studio and retry to open the emulator. The log file will be recreated with a lot less history and so it will be so much easier to search. In my case, i found: manager.EmulatorProcessHandler - Emulator: emulator: ERROR: Another emulator instance is running. Please close it or run all emulators with -read-only flag.. Given that, it is easy to solve. I just had to open a process manager and terminate the emu process that didn't correctly close for some unknown reason. Of course, in our case the log will be completely different. But now you have a clue of the hidden criminal.

对我来说(我在网上看到其他人也遇到了这种情况)，这是因为我在后台运行Riot的Vanguard软件。这不足以杀死托盘中的进程(我在Windows上)，我必须将其设置为启动时不运行，然后重新启动我的计算机。之后，我就可以正常启动我的虚拟设备了。

面对类似的问题，尝试上述解决方案，它没有工作。

如果上述建议不能解决问题，我想提出一个简单的解决方案。

解决方案-尝试清理系统中的空间。我的问题是，当我试图启动模拟器时，只剩下1GB的空间，在清理空间后得到8GB，并能够启动模拟器。

安装英特尔x86模拟器加速器对我来说很有效。

我也遇到了同样的问题。尝试了不同的解决方案

将“图形”改为“软件” 更新android studio sdk到最新版本 使缓存无效/重新启动android studio

但问题是我的磁盘已满，模拟器无法保存必要的文件。所以如果有人遇到这个问题，请确保你有至少10GB的可用空间(对于安装在像素4 2021的android 11)
