Dockerfile说明：

• 在前文SDK的镜像构建方法之中已经说明：https://liumiaocn.blog.csdn.net/article/details/103640872
• FROM：是唯一的不同之处，前面SDK镜像只是用OPENJDK作为基础镜像，而本文示例则使用Gradle 6.0.1的镜像作为基础镜像。

镜像下载

下载命令：docker pull liumiaocn/android:sdk.26.1.1.gradle.6.0.1

版本确认

Demo应用

此镜像与前文的gradlew使用方式的镜像有所区别，gradlew更像是一个带着gradle安装程序的配置文件方式，所以需要一个包含gradlew配置的工程在镜像之中，本文的镜像更为纯粹，就是Android工程的构建环境：Android SDK + Gradle，所使用的代码工程如下所示：

• https://github.com/liumiaocn/easypack/tree/master/containers/standard/android/Demo

apk构建

使用时通过-v将待构建的内容挂载到容器中，然后执行构建即可
