MVP implementation of the challenge

The current implementation is done with the provided techStack and also added the next libraries:

• swiperefresh layout
• recyclerview
• Gson for retrofit parsing
• mockito for testing purposes

Approach:
As per requested MVP is used as pattern for the client solution. For network layer a data provider was created using RX to execute network requests, and in order to solve the lifecycle integration of the singleton data provider, live data is being used to subscribe to the network results in the ui.

The presenter is initialized along with the view, this way if the view is destroyed, the presenter is destroyed as well, so no memory leak issues when the Presenter interface is implemented by the UI.

Unit Test

unit test was provided for the presenter logic, using only JDK not Android environment, this are the faster test that do not require an emulator running.

Android test

Android tests were not requested but it is possible to inject mocks of the DataProvider and verify the ui is presented properly on the screen with Espresso.
