GitHub Repository Search Information Android App

Table of contents

Overview

This Android application allows the user to input a GitHub repository name in the following format: /, for example, bright/shouldko. When the repository name is provided, the app fetches and displays the following information about it using the GitHub API:

  • Repository ID
  • List of commits in the repository
  • Each commit is described by message, SHA value, and author's name
  • List is sorted by date, with the latest commits at the top The app caches the previously used repositories data, and the user can access the history of the last used repositories. Using the history, the user can open the repository information again in the same way as if they typed the repository name manually again.

Even when the app is offline, the user can still see the previously fetched repository information.

Additionally, the user can send selected commits' data (message, SHA value, author's name) using a 3rd party application installed on the phone (e.g., an email client or Facebook Messenger) in the following way:

  • The commits on the list can be selected and unselected
  • The user selects at least one commit on the list
  • The user taps a "send" button
  • The user is asked by the system to choose an application they want to use for sending a message
  • A new message in the selected app already contains passed commits information so that the user does not have to copy-paste it manually.

Architecture

The application is built using the following technologies:

  • Kotlin
  • Compose
  • Koin
  • Coroutines
  • Flow
  • Retrofit
  • Room local database
  • Compose Navigation
  • ViewModel

The application architecture follows the following design pattern:

  • Clean Architecture
  • MVVM
  • Use Cases

This design pattern ensures maintainability, testability, and scalability. Despite the app and it's features are small I have implemented and designed the architecture as it would be for bigger application. This application is open for extension of any features related as well.

  • The app only supports sending data to 3rd party applications installed on the device, and it does not support sending data to web services or APIs directly.

Future Improvements

  • Internet connection observer which is notifying user regarding phone internet connection (Snackbar with notification)
  • UI/UX improvements for a more intuitive and user-friendly experience
  • Add autocomplete option to input fields to be able to prompt user with possible search query results
  • Implement unit tests
