Features :

• Display list of venues for a location.
• Observe location changes and update venues list whenever a new location is detected.
• Display a message informing the user that the app is going to fetch new venues because he/she had moved, with an action "Cancel" to cancel the update of venues.
• Display of a venue item with its image, name, ratings and price.
• Display a venue in a detailed view when a venue item is clicked.
• Animating the display of detail view from the list of venues.
• Support for Marshmallow permissions (Asking for each needed permission).

Implementation :

• Implemented entirely in Kotlin.
• Heavy use of Reactive paradigms (with RxJava, Retrofit and RxBindings).
• Unit tests (with mocking of foursquare service).
• Gradle dependencies organised in a maintainable way (dependencies.gradle).
• Using an MVP structure.
• Dependency injection with Dagger2.
• Taking advantage of android build types to use a debug build for features such as logging that we don't want on release builds.
• Testing: using Mocks with retrofit

Focus on:

Minimize mutability

• Use val most of the time for immutability and minimise the use of var.

Idiomatic use of kotlin

• Use extensions
• Use apply
• Use of kotlin higher order functions to have a LINQ-style code

Rx

• Don't break the chain.
