经过多次尝试，并尝试了许多我可以在stackoverflow或互联网上其他地方找到的解决方案，我仍然无法在我的计算机上运行模拟器。这台计算机在Windows和Linux引导下都会发生这种情况。我能够启动模拟器，但它仍然是一个完整的黑屏。以下是关于软件的一些信息:我正在使用的Linux Ubuntu 20.04LTS和Android-studio版本:4.1.2。关于我的硬件:

首先我检查了虚拟化工作，它似乎很好。

对于flutter doctor，它写的是设备离线，我有一个全黑屏。在这里，我尝试了很多方法，用硬件或软件渲染图形，改变RAM，改变核数，改变x86或x86_64的CPU arch，……$flutter doctor

当执行adb devices命令时:
$adb devices
List of devices attached
adb server version (41) doesn't match this client (39); killing...
* daemon started successfully
我总是在最后得到这个错误:等待模拟器上线300秒后超时。
我试图做adb server-killer等，做冷启动等，…毫无效果。我还是有同样的问题。以前我用的是另一台电脑，一切都很好。我完全在这里挣扎。
$adb kill-server
$adb start-server
* daemon not running; starting now at tcp:5037
* daemon started successfully
当运行logcat时，我得到了一个重启循环。

你知道我到底错过了什么吗?我不能发布图片。我希望你能帮助我。多谢,
我终于找到了解决办法。因为我使用的是旧的AMV处理器，所以我需要为模拟器使用基于ARM的映像，而不是x86映像。然后我就可以运行它了。不幸的是，我的处理器不够强大，并且在启动android模拟器时非常滞后。我不得不买一台新电脑。
