Android Basic Retrofit and Room Sample

This is a simple implementation of Android Architecture Components: https://developer.android.com/topic/libraries/architecture/guide.html
It is based on the one of Philippe Boisney: https://github.com/PhilippeBoisney/GithubArchitectureComponents although my approach is simpler without using Dagger nor ButterKnife.

Getting Started

This simple app has onle one screen. When it starts, it will fetch photos of a given album from the API https://jsonplaceholder.typicode.com/photos and it will save this info into a database. The photos are shown in a RecyclerView. Only when the photos in the database are not fresh enough they will be downloaded again. In order to browse photos there is a Spinner to choose the album and an EditText to enter a photo title. When restarting the activity or rotating the device the screen keeps the same information.(One of the good things of using ViewModel and LiveData).
