使用Android Studio的Android模拟器时，我发现在Java WebView小部件中显示支持WebGL的复杂图形网页时出现问题(
With Android Studio's Android Emulator I'm seeing a problem displaying a complex WebGL-enabled graphics web page in a Java WebView widget (PixiJS demos appear blank in WebView on Android emulator). But I can only reproduce the problem with Android Emulator 27.1.12-4623001. It runs fine for my colleagues running Android Emulator 26.1.4-4266726.

我查看了 Android模拟器发行说明页面，但我没有请参阅有关如何降级旧版本的说明.我确实尝试降级Android Studio 本身，但是即使安装了Android Studio 2.2.3，仿真器仍为27.1.12-4623001.我甚至通过遵循如何完全卸载Android Studio来删除Android Studio 3.0.1..
I looked on the Android Emulator Release Notes page but I don't see instructions on how to downgrade old versions.

I even deleted Android Studio 3.0.1 by following How to completely uninstall Android Studio?.

推荐答案
Google支持人员说我可以下载旧的Android Emulator版本，如下所示:
Google support said I could download old Android Emulator versions as follows:
http://dl.google.com/android/repository/emulator-darwin-4266726.zip (适用于Mac) http://dl.google.com/android/repository/emulator-windows -4266726.zip http://dl.google.com/android/repository/emulator-linux -4266726.zip
http://dl.google.com/android/repository/emulator-darwin-4266726.zip (for Mac) http://dl.google.com/android/repository/emulator-windows-4266726.zip http://dl.google.com/android/repository/emulator-linux-4266726.zip
如果要下载以前的任何内部版本，则只需将#(在major.minor.patch-#中的一个)与darwin/windows/linux一起放入即可.
Basically, just put the # (the one in major.minor.patch-#) along with darwin/windows/linux if you'd like to download any previous build.
要在我的Mac计算机上安装，请执行以下操作:
To install on my Mac computer, I did as follows:
-
下载 http://dl.google.com/android/repository/emulator-darwin-4266726.zip 通过Chrome进入〜/Downloads
Download http://dl.google.com/android/repository/emulator-darwin-4266726.zip via Chrome into ~/Downloads
备份主仿真器目录:mv ~/Library/Android/sdk/emulator ~/Downloads/emulator-backup
替换主仿真器目录:mv ~/Downloads/emulator ~/Library/Android/sdk/
重新启动Android Studio
Restart Android Studio
之后，Android Emulator版本降级为26.1.4-4266726.
