Android Card Factory Challenage

An android development challenge for showing cards

Introduction

In this challenge, you are going to develop an android Card app which shows a random card on the main activity and has a 'Try' button. Whenever the user clicks on the 'Try' button, app should show him another random card which is not seen up to now.

Each card has at least 2 items:

title
description

We have different Cards which are shown differently:

Picture Card which shows a picture at the end of card content (code is 0)
Vibrator Card which vibrates the device when it is shown (code is 1)
Sound Card which plays a sound when the card is shown (code is 2)

Cards can be shown in different themes meaning they will use a different icon and color representing their tag:

sport
art
fun

You can choose your desired icon and color for each theme.

You should initialize cards list from this URL: http://static.pushe.co/challenge/json
