A Video Recipe App as a part of Advanced Android App Development

This app will allow a user to select a recipe and see video-guided steps for how to complete it. It requests the data from Internet in form of JSON. The JSON file contains the recipes' instructions, ingredients, videos and images you will need to complete this project. Don’t assume that all steps of the recipe have a video. Some may have a video, an image, or no visual media at all. This app makes use of fragments very efficiently on the tablet as well as phone screen. The fragments functionalities are being re-used in both screens.
