🍿MVVM + Dagger Hilt + Android Architecture Components
Model is implemented as Repository pattern. Firstly it begins from internet connection checking. Consequently if it's alive we're retrieving data from the server (by using Retrofit 2). Otherwise we're trying to fetch data from the cache itself.
View is realised as 2 fragments. First one contains RecyclerView, second one depends on clicks on recycler-items and finally displays detailed data fetched from the Model. It implements state saving reflected on configuration changes.
ViewModel is responsible for transferring data between view and model.
– Implementation of dependency injection for communication between app modules
– AndroidInjector applying for injecting into View components
– Unit-testing simplifying
Fragments
– interactive displaying and click reflecting
Data Binding
– replace basic operations with UI (e.g. findViewById() ) to the XML
