Code Database Android

This is an android app which consumes the REST API defined in Code Database which was done with django-rest-framework.

Key Features

1. Kotlin multiplatform data layer
2. Jetpack Compose and Material 3 design
3. Model View Intent(MVI) architecture followed
4. Token Authentication for user login/logout

I know it's a lot. Let me explain one by one...

1. Kotlin Multiplatform Data Layer

The backend data layer is done completely as a Kotlin Multiplatform(KMP) library and integrated with the android app. The iOS app is not configured yet, but can be done with minimal setup.

Features:

• Network calls with Ktor client
• Followed clean architecture and manual dependency injection done using service locator pattern
• Response serialization done with Kotlinx serialization
• Local in-memory cache maintained for swift search and filter functionalities

2. Jetpack Compose and Material 3 design

The application's UI is done using Jetpack Compose using compose-navigation and following the Material 3 design guidelines inspired by .

3. Model View Intent(MVI) architecture

• The app uses the Model View Intent architecture by declaring the UIStates in screen's view model
• The screen only reacts to the changes happening in the UIStates which enforces unidirectional data flow
• Any operations from the screen are posted as Events to view model which processes the event and updates the UI state if required
• The app's architecture follows the common guidelines recommended by android documentation

4. Token Authentication for user login/logout

• User login/logout functionalities are also implemented in the app
• A token generation API was written in the web app using Django rest framework authtoken and a token is generated on every user login
• Every calls in app will pass that token as a Authorization header to get that user specific response
• On logout the token will be removed. The refresh and revoke access token is yet to be implemented.
