Android developer nanodegree: Project 2
You will productionize an app, taking it from a functional state to a production-ready state. This will involve finding and handling error cases, adding accessibility features, allowing for localization, adding a widget, and adding a library.
As Android projects grow in complexity, it becomes necessary to customize the behavior of the Gradle build tool, allowing automation of repetitive tasks. Particularly, factoring functionality into libraries and creating product flavors allow for much bigger projects with minimal added complexity.
In this project you will:
- Use MediaPlayer/Exoplayer to display videos.
- Handle error cases in Android.
- Add a widget to your app experience.
- Leverage a third-party library in your app.
- Use Fragments to create a responsive design that works on phones and tablets.
Your task is to create a Android Baking App that will allow Udacity’s resident baker-in-chief, Miriam, to share her recipes with the world. You will create an app that will allow a user to select a recipe and see video-guided steps for how to complete it.
The JSON file here 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. One of the skills you will demonstrate in this project is how to handle unexpected input in your data -- professional developers often cannot expect polished JSON data when building an app.
- App should display recipes from provided network resource.
- App should allow navigation between individual recipes and recipe steps.
- App uses RecyclerView and can handle recipe steps that include videos or images.
- App conforms to common standards found in the Android Nanodegree General Project Guidelines.
- Application uses Master Detail Flow to display recipe steps and navigation between them.
- Application uses Exoplayer to display videos.
- Application properly initializes and releases video assets when appropriate.
- Application should properly retrieve media assets from the provided network links. It should properly handle network requests.
- Application makes use of Espresso to test aspects of the UI.
- Application sensibly utilizes a third-party library to enhance the app's features. That could be helper library to interface with Content Providers if you choose to store the recipes, a UI binding library to avoid writing findViewById a bunch of times, or something similar.
- Application has a companion homescreen widget.
- Widget displays ingredient list for desired recipe.
Baking app was highly evaluated by certified Udacity code reviewer and was graded as "Exceeds Specifications".
