A GitHub Action to Build Modular Android Projects

rosariopfernandes profile image Rosário Pereira Fernandes ・2 min read

My Workflow

As most Android Developers know, an Android Project may have many
different modules.

If you change one single module and submit a Pull Request, most CI workflows will try to build/test all the existing modules, which might take a lot of time, when in reality you only need to build the module you changed.

This GitHub Action aims to solve that problem. When you submit a Pull Request, it will only build the module you changed,or no module at all if you left them untouched (in case of documentation or configuration changes).

Real Project Showcase

Take a look at this project I forked: quickstart-android. It contains many different modules (admob, analytics, database, etc).

I made a change to the database module and sent a Pull Request:

refactor(database): make a demo change for the Github Actions Hackathon #11

I'm hoping that this PR will only build the database module, since that's the only change I made.

GitHub Actions built the database module only and finished in 4m 40s, as seen in the log.

Building the whole project generally takes around 17min, as seen in this log.

Github Actions for Modular Android Projects

As most Android Developers know, an Android Project may have many different modules.

If you change one single module and submit a Pull Request, most CI workflows will try to build/test all the existing modules, which might take a lot of time, when in reality you only need to build the module you changed.

Usage

Add it to your workflow YAML like this:

    - name: Build with Modular Action
      uses: rosariopfernandes/modular-android-action@v0.2.0
      with
        for-each-module: 'assembleDebug'
        for-all-modules: 'check'

As you can see, it takes 2 arguments:

  1. for-each-module - gradle task to run for each module.
  2. for-all-modules - gradle…
