SafTechWeather ⛅

An Android weather application implemented using the MVI pattern and clean architecture, Retrofit2, Dagger Hilt, Kotlin Flows, ViewModel, Coroutines, Room, Jetpack Compose, Kotlin DSL and some other libraries from the Android Jetpack . SafTech Weather fetches data from the Weather API to provide real time weather information.

Architecture

The architecture of this application relies and complies with the following points below:

clean_architecture_image

Technologies used:

  • Jetpack Compose - A modern toolkit for building native Android UI
  • Gradle Kotlin DSL - An alternative syntax for writing Gradle build scripts using Kotlin.
  • Version Catalogs - A scalable way of maintaining dependencies and plugins in a multi-module project.
  • Retrofit a REST Client for Android which makes it relatively easy to retrieve and upload JSON (or other structured data) via a REST based webservice.
  • Dagger Hilt for dependency injection.
  • ViewModel to store and manage UI-related data in a lifecycle conscious way.
  • StateFlow to enable flows to emit updated state and emit values to multiple consumers optimally.
  • Kotlin Flow to emit a stream of data with multiple values sequentially.
  • Timber - a logger with a small, extensible API which provides utility on top of Android's normal Log class.
  • Material Design an adaptable system of guidelines, components, and tools that support the best practices of user interface design.
  • Coroutines used to manage the local storage i.e. writing to and reading from the database. Coroutines help in managing background threads and reduces the need for callbacks.
  • Room persistence library which provides an abstraction layer over SQLite to allow for more robust database access while harnessing the full power of SQLite.
  • Paging Library helps you load and display small chunks of data at a time.
  • Android KTX which helps to write more concise, idiomatic Kotlin code.
