Creating an Android project from the command line using Docker

Question

I inherited the Android Java code in my company, without Gradle files, etc., and I want to be able to compile this on my dev server (I program from a ChromeOS computer, therefore, connecting the CLI SSH to the server where I doing dev stuff). Now I have found some Docker images, such as https://hub.docker.com/r/ksoichiro/android/ (with a broken command line example), but so far I have not been able to create an APK. What am I missing and how will you do it?

You have three steps:

• Move the project to gradle.

  It’s not so difficult as there is a lot of gradle project there, and you can try to follow it or just read “Migrating to Gradle” .

• Create a project with gradle on the local machine.

  If you performed the migration correctly, you can build your project in the terminal, for example:

  ./gradlew assembleDebug

  but it could also be DevDebug or assemblyProdRelease assembly, which depends on your buildType and flavor in gradle. Check which assemblies are available by running:

  ./gradlew tasks

• Create a project using Docker.

  Based on linked image:

  docker run -t -i ksoichiro/android -v /path/to/project:/workspace -w workspace /bin/sh -c "./gradlew assembleDebug"
