List GitHub Repos using Paging Library

This application is created to show how paging library can be used to load infinite lists
and used in conjunction with Network fetch & Room Database.

Tech Stack Used

1. Android Architecture Components (Room Database, LiveData, Paging Library(PagedList, PagedListAdapter)).
2. Application Architecture is MVVM.
3. Networking using Retrofit 2.
4. Used Kotlin.
5. Used Kotlin Coroutines for Async Operations.
6. Used Retrofit 2 Adapter for Kotlin Coroutine’s Deferred type.
7. Whole project is based on AndroidX.
8. Used Dagger 2 for Dependency Injection.
9. Picasso for Image handling.

Steps

1. Request the GitHub API to show public repositories and parse the JSON
   response.
2. Display a list of repositories, each entry shows
   • full repo name
   • description
   • login of the owner
   • forked or not
   • repo owner’s avatar image
3. Requesting 15 repos at a time over the netwokr. Using an endless list with a load more mechanism. The
   load more is triggered when the scrolling is 5-items near to reaching the end of the
   list.
4. Cache the repos in room database storage.
5. Show a light green background if the fork flag is false or missing, a white one
   otherwise.
6. On a long click on a list item showing a bottom sheet to ask user if go to repository html_url or
   owner html_url which is then opened in the browser.

TODOs

• Implement a mechanism to download and store the repos on a regular interval also if the app is closed.
