This repository shows how to separate layers of an application for newborn in Android world with a simple application based on Foursquare API. After this you will become a babyd Padawan and this means that you have made a great progress to become a real Padawan and then a JEDI.
Important note: For learning puprposes this repository does not contain Dependency Injection with Dagger2 in order to be easier for newborn Android developers.
If you understood this simple architecture you will be able to go further in Android World and more complex and cleaner architecutes like MVP, MVVP.
The architecture is simple. Check below:
A quick description is that I separated the presentation layer and the data layer. The data layer is a simple java library and not an android library although it can be an Android Library also. eg. if you want to access a database and you need the context. In this repository there is a an example with a naive login/register API endpoints (check server-naive directory) and an example to request Songs by iTunes REST API.
The data layer doesn't know anything about the presentation layer is completely agnostic about it. The data layer can access a Database or a REST API and it will return back to presentation layer business objects (Entities in this case).
Important note: You must not send back to the presentation layer the Data Object (DTO of retrofit) because you need to have a business object with business rules (Domain layer in MVP architecture), that's why we need DataMappers which will convert the DTO to BO.
