Technical Summary

  • Offline-First: The offline-first apps, while still requiring a connection to the servers, don't need a constant internet connection. The data from servers is downloaded to the user's device and can still be accessed offline.
  • Single Source of Truth (SSOT): It is the practice of structuring information models and associated schemata such that every data element is stored exactly once. You can have an offline app and be sure your data always use one source and that is your database.
  • Model-View-ViewModel (MVVM): It is a software architectural pattern that facilitates the separation of the development of the graphical user interface (without using DataBinding). Also, there are Screen States to handle the different states in the UI.
  • Coroutines: A coroutine is a concurrency design pattern that you can use on Android to simplify code that executes asynchronously.
  • Android Architecture Components: Collection of libraries that help you design robust, testable, and maintainable apps.
    • Navigation: This component helps you implement navigation.
    • LiveData: Data objects that notify views when the underlying database changes.
    • ViewModel: Stores UI-related data that isn't destroyed on UI changes.
    • Paging 3: The Paging Library helps you load and display small chunks of data at a time. Loading partial data on demand reduces usage of network bandwidth and system resources.
    • Room: The library provides an abstraction layer over SQLite to allow for more robust database access while harnessing the full power of SQLite.
      • DatabaseView: This annotation allows you to encapsulate a query into a class. Room refers to these query-backed classes as views, and they behave the same as simple data objects when used in a DAO.
  • Retrofit 2: A Retrofit 2 Converter.Factory for Kotlin serialization.
  • Detekt: A static code analysis tool for the Kotlin programming language. It operates on the abstract syntax tree provided by the Kotlin compiler.
  • Kotlin Gradle DSL: Gradle's Kotlin DSL provides an alternative syntax to the traditional Groovy DSL with an enhanced editing experience in supported IDEs, with superior content assist, refactoring, documentation, and more.
  • GitHub Actions: Automate, customize, and execute your software development workflows right in your repository. Discover, create, and share actions to perform any job, including CI/CD, and combine actions in a completely customized workflow.
  • Moshi & Moshi Converter: A modern JSON library for Kotlin and Java. The converter uses Moshi for serialization to and from JSON.
  • Timber: A logger with a small, extensible API which provides utility on top of Android's normal Log class.
