Technologies used:

• 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 for dependency injection.
• ViewModel to store and manage UI-related data in a lifecycle conscious way.
• LiveData to handle data in a lifecycle-aware fashion.
• Navigation Component to handle all navigations and also passing of data between destinations.
• 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.
• Data Binding to declaratively bind UI components in layouts to data sources.
• Room persistence library which provides an abstraction layer over SQLite to allow for more robust database access while harnessing the full power of SQLite.
• Android KTX which helps to write more concise, idiomatic Kotlin code.
