docker上的Android SDK

我试图在docker上运行android emulator，但我得到了以下错误，我做了一些研究，但没有任何答案帮助我实现我的目标，这是我得到的错误和我的docker文件，我尝试了armeabi和系统映像；安卓-29；谷歌API；x86和两者都不起作用

我在我的MAC上执行相同的步骤，它工作正常，这是我的docker文件：

首轮

xhost +

然后像这样运行docker容器

docker run -i -t --net=host --privileged --env="DISPLAY" \
-v $HOME/.Xauthority:/root/.Xauthority:rw \
-v ~/disk1/android_docker:/home/android \
android-image /bin/bash

然后你就可以跑了

我遇到了一个类似的问题，结果是我们的脚本运行的模拟器版本不正确（26，它还没有很好地支持headless）

它应该在运行

$ANDROID_HOME/emulator/emulator -avd avd-name -no-skin -no-audio -no-window

而不是工具文件夹中的模拟器

只需运行可执行文件即可检查仿真器的版本。我的输出（有效）是

你解决了这个问题吗？@jamesNewbould，说实话，我放弃了，但不知怎么的，这是可行的。如果你明白了，请告诉我
