Adyen Android Assignment

This repository contains the coding challenge for candidates applying for a Senior Android role at Adyen. It consists of two unrelated parts:

1. Cash Register

Your first task is to implement a cash register. See the cashregister module.

Criteria:

• The CashRegister gets initialized with some Change.
• When performing a transaction, it either returns a Change object or fails with a TransactionException.
• The CashRegister keeps track of the Change that's in it.

Bonus points:

• The cash register returns the minimal amount of change (i.e. the minimal amount of coins / bills).

2. App

Your second task is to implement a small app using the Foursquare Places API. See the app module.

The app should show a list of venues around the user’s current location. Decide yourself which venue details should be relevant to the user. You have full freedom on how to present data on screen. We've already added some code to make it a bit easier for you, but you are free to change any part of it. We are going to check your implementation for understanding Android specifics (like handling configuration changes), UX choices, and overall architecture. You are free to add any feature or code you want, but we also value quality over quantity, so whatever you decide to do, try to show us your best.

Setup

Add your Foursquare client ID and secret to local.gradle. See local.gradle.example for details. Tip: You can verify your credentials with src/test/java/com/adyen/android/assignment/PlacesUnitTest.kt
