为什么安卓模拟器不工作

Question

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，但模拟器无法正常工作。

所有 SDK 工具都已安装和更新。以下是我运行空白活动时的事件日志和空白活动（Hello World！）的 Logcat。

Answer 1

我进入模拟器扩展控制中的“设置”->“高级”，然后进入“高级”，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），并且错误似乎已经消失现在屏幕不再显示白屏，而是显示谷歌地图，这就是程序应该做的事情。这看起来是一个很好的解决方案吗？我还应该做更多事情以免将来陷入困境吗？
