SharedPreferences is a very common and usefull API of Android SDK to store simple key-value pair data for any Android App. In this repository, I implemented the SharedPreferences with Dagger 2 Dependency Injection framework. Please be mentioned that, it's not mandatory to implement SharedPreferences with Dagger. This repository is for practicing the Dagger stuff. If you want to know the basic implementation of SharedPreferences without Dagger, then check this repository.

Basic knowledge of Kotlin and SharedPreferences API.

We will develop a simple single page Application. This App will store user name and website data in SharedPreferences. The main target is implementation the SharedPreferences things using Dagger dependency injection.

No special things required for this project setup. Simply clone, sync gradle and run!

Generally we create an instance of SharedPreferences inside our Activity. But in this project, we don't create the instance of SharedPreferences from our Activity class. Rather than, the instance of SharedPreferences will be injected into Activity class when the activity class is created. This injection is implemented by Dagger 2. Activity class don't need to know anything about the creation process of SharedPreferences instance.

There are some other ways of implementation of SharedPreferences and Dagger. It is not guaranteed that my approach is the best in all cases.
