Sample android application project to showcase different ideas or concepts.

The app is a simulation of an e-commerce application with two main screens: a catalog of products and a shopping-cart.

1. Clicking in a product would add the element to the Cart.
2. A small notification will be shown every time that something is added to the Cart.
3. From the Cart the products can be removed by clicking on them.
4. There would be a count indicator in one of the tabs (the cart one) with the number of items included in the Shopping Cart.
5. When something is added/removed from Cart the counter and content of the cart screen must be updated accordingly.
6. "About" screen can be opened by menu item click.
7. The following interaction events are sent to the analytics: add to cart, remove from cart, checkout.
8. The following screen view events are sent to the analytics: product list, cart, about.

Tracking demo: you will need to setup Google Analytics, Firebase and Flurry accounts to be able to see tracking output.

• Google Analytics and Firebase Analytics: Follow instructions to get your google-services.json configuration file and add it to the project.
• Flurry: follow instructions to get your key and set it in TrackingDispatcher.
• To see the data being sent by tracking tools you need to setup a proxy tool (e.g. Charles or mitmproxy) and add the corresponding SSL certificate on your test device.
