  • Sample app using Retrofit + Dagger + RxJava using 500px api.
  • Supporting api>=18


  • Add your consumer key by creating a file under app directory. File should be like API_KEY=YOUR_API_KEY
  • You can get an API consumer key here: 500px Consumer Key
  • You’ll first need to log in with your 500px account. Please create a 500px account if you don’t yet have one.

Architecture Pattern

#Coding Style

#Key Concept There are 2 screens in the app

Each Screen has

  • A contract defining the view and the presenter
  • An Activity which is responsible for the creation of fragments and presenters
  • A Fragment which implements the view interface.
  • A presenter which implements the presenter interface

In general, the business logic lives in the presenter and relies on the view to do the Android UI work. The view contains almost no logic: it converts the presenter's commands to UI actions and listens to user actions, which are passed to the presenter.

Special Thanks To
