An application implemented using MVVM pattern, LiveData, ViewModel, Kotlin-Coroutines, Room, Navigation Components and DataBinding

Shopping List

Introduction

An Android application that integrates the Android Jetpack components to help keep track of items needed when shopping.

Architecture

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

• A single-activity architecture, using the Navigation Components to manage fragment operations.
• Pattern Model-View-ViewModel(MVVM) which facilitates a separation of development of the graphical user interface.
• Android architecture components which help to keep the application robust, testable, and maintainable.

Technologies used:

• 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.
• Kotlin Coroutines for managing background threads and reducing needs 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.

Testing

• JUnit - a simple framework to write repeatable tests.

Installation

Shopping list requires a minimum API level of 19. Clone the repository and run.
