Simple project demonstration

Assumption I made

• As the response body has a commom pattern, I assumed I could make a generic dialog picker for all of the requests
• I also assumed that layout is not the most important for this assignment, as I'm terrible at designing I didn't care about it

About the project

The project is in Kotlin, implemented using MVVM pattern (I started the project using MVP but I decided to switch to MVVM) with dependency injection using Kodein. For retrieving data from the network I used Retrofit with RxJava and implemented a repository to abstract the data load.

For paged requests I used Android Paging Library from Architecture Components

The project is on a private repository on Github. It was developed using gitflow so you can check the commits and the progress of the development. Please, give me a git user which I can add as a collaborator of this repository.

Stack I used:

• Android Gradle Plugin 3+
• Android API 16+
• Kotlin
• MVVM
• Paging Library
• Retrofit
• Kodein
• RxJava
• GSon
• JUnit
• Mockk
• Ktlint
• Detekt

Test

• Unit tests

Lint

Android SDK already has a lint toolkit so if you want to edit the severity of problems jumps to lint.xml in this project.

I also used ktlint and detekt for code smells. To run it, just execute: ./gradlew check

TODO: Improvements if I have more time, I would

• definitely, do a better UI
• cache strategy
• increase code coverage
• integration tests
• make a search on picker dialog
• refactor PickerDialogFragment to reduce its complexity
