Development
Develop in kotlin with intensive usage of coroutine. Follow the MVVM architecture with android architecture component (LiveData - ViewModel - Room) and use dependency injection with Koin.
The biggest challenge was to handle Android background tasks to refresh servers status. It use Android worker but it wasn’t enougth so it also use the basic android alarm manager. I thinking about writting an article on how to achieve this correclty.
I also had some difficulties to get the mobile signal quality. I write an article about that here.

Pipelines

One build pipeline write in yaml (to keep history on the git repository) that trigger on the develop and release/* branches. This pipeline:
- Build the project
- Create the release apk signed and unsigned
- Create the release app bundle (aab) signed and unsigned
- Execute unit test and instrumented test (on simulator)
- Execute the code coverage (with unit and instrumented tests using Jacoco)

Release
Two release pipeline. One for the Google PlayStore, one for the Amazon AppStore.
The Amazon AppStore release use the Amazon Devops Extensions I made. It prepare the release and then publish it. It has only one manual task between the too steps, update the application description and changelog.
The Google PlayStore release is fully automatized from the testing release to the production release. It use the metadata files hierarchy to update the PlayStore description.
