An application with Dagger 2, shared preference, retrofit API and Room storage. Each and every concept is implemented in separate activity for beginners.

In my previous Git repo I have provide Dagger 2 in simple steps. It is available here.

Here in this repo I've used shared preference, API calling(Retrofit) and persistance storage(Room DB) with the help of dependency injection(Dagger 2).

• SimpleActivity.java: - for simple Dagger 2 introduction and basic functionality (info available here)

• PreferenceActivity.java: - for storing and retriving data from SharedPreferences

Preferences and utils will be injected through dagger component.

• NetworkActivity.java: - for calling API using Retrofit

Retrofit setup and call is done in NetworkModule and injected in activity thought dagger.

• PersistenceActivity.java: - for storing and retriving data from Room

Room setup and DAO is defined in PersistenceModule and injected in activity thought dagger.

Each specific component holds an respective custom scopes.
