Course Description

In this course: Android Jetpack DataStore, you will learn the fundamentals required to implement DataStore with MVVM architecture to persist your key-value pairs and typed objects with protocol buffers in your jetpack compose apps. First, you will learn the difference between SharedPreferences and DataStore, and why DataStore is preferred over SharedPreferences. Secondly, you will learn the two implementations of DataStore namely: Proto and Preference Data Store. Thirdly, you will learn how to create a preference DataStore, to read and write from it. Then you will learn to create a Proto DataStore and how to read and write from it. Then you will learn to create a Repository layer that interacts with both Data Store, and integrate the Repository layer with the UI layer i.e the ViewModels and your Composables. Additionally, you will learn how to test and debug your DataStore. Finally, you will learn the pros and cons of each type of DataStore implementation and their use cases.

By the end of the course you will have mastered:

Tabulate the differences between SharedPreferences, Preference DataStore and Proto DataStore
Understanding Preference Data Store and Proto DataStore
Reading and Writing From Preference Data Store
Writing and Reading From Proto Data Store
Testing Preference Data Store and Proto DataStore
Integrating both Preference and Proto DataStore in MVVM Architecture with Jetpack Compose
Exploring the pros and cons of Proto DataStore and Preference DataStore
