不全面 Android Studio - Device emulator-5554 处于离线状态。错误 - 仅显示黑屏
Uncomprehensive Android Studio - Device emulator-5554 is offline. error - Showing only black screen
经过多次尝试，并尝试了很多我可以在 Whosebug 或互联网其他地方找到的解决方案，我仍然无法 运行 我的计算机上的模拟器。这台计算机在 Windows 和 Linux 启动时都会发生这种情况。我能够启动模拟器，但它仍然是全黑屏幕。
以下是有关该软件的一些信息：Linux Ubuntu 20.04LTS 和 Android-studio 我正在使用的版本：4.1.2。

你知道我可能遗漏了什么吗？我无法 post 图片。
我希望你能帮助我。
非常感谢，
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。
不得不买一台新电脑。
