MapTheCity

Small showcase application that loads 200k rows of cities from a JSON file in the assets folder and presents them to the user. The cities contain name, country code and coordinates and can be located on a map.

The app has been tested on:

• Google Pixel 3 XL API 29
• Google Nexus 9 API 25

Possible improvements:

• Use DI framework (Dagger 2, Koin) as a replacement for the ServiceLocator pattern used.
• Use a DB framework such as Room.
• Create data sources for the repository for a better separation of concerns, as recommended in Google's Guide to app architecture.
• Create a backend service to fetch the list of cities from a server, instead of from the assets folder.
• Improve (or remove) the About button and its functionality.
• Augment unit test coverage of the app in general.
• Tackle flaky UI tests, as sometimes some of them pass when run alltogether, and sometimes they don't (specially using the Github Action workflow instrumented tests).
