当我几天前更新Android Studio时，Android Emulator停止工作。我尝试打开一个空白活动，但模拟器也无法正常工作。
所有 SDK 工具均已安装并更新。下面是我运行空白活动时空白活动(Hello World！(的事件日志和 Logcat。

我转到模拟器中扩展控件中的设置>高级，然后转到高级并将 OpenGL ES 渲染更改为 SwiftShader，将 OpenGL ES API 级别更改为兼容性(OpenGL ES 1.1/2.0(，错误似乎已经消失，屏幕现在不显示白屏，而是显示谷歌地图， 这就是程序应该做的。 这似乎是一个很好的解决方案吗？我应该做的还有什么事情来避免将来搞砸吗？
