Sprint 4 was used mostly to finish up the documentation needed for this project. The portfolio was updated and the research questions ended up being answered.

As for coding I used SonarLint to improve the quality. I tried to make some unit tests and a DevOps pipeline to ensure stability. I also added an all new settings screen where API keys, warehouse locations and user preferences can be recorded. The users can now also log in and out of the app as intended.

By the end of the sprint the app should be uploaded to the play store for Zebra devices only so we can do some testing and keep updating it with new features and bug fixes.
