Super Duo!

Project Overview

You will productionize two apps, taking them 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

Why this Project?

Super Duo gives you an opportunity to diagnose problems in a pair of apps and also practice improving apps. These skills are vital to building apps users will love.

Diagnosing issues with existing apps is key to working on large apps or continuing projects in Android. Being aware of the common pitfalls in app design frees a developer to produce novel app experiences without making the same mistakes over and over.

What will I learn?

In this project, you will:

  • Diagnose existing issues with an app.
  • Make an app accessible to sight-impaired users.
  • Allow your app to be localized for distribution in other countries.
  • Handle error cases in Android.
  • Add a widget to your app experience.
  • Leverage the functionality of a library in your app.

Required Tasks

  • Download a zip file of each of the two apps from the Downloadables section.
  • Read the UX Review in the next node.
  • Spend time exploring the current state of the apps, looking for ways they could be improved. Each app will need 2 or 3 improvements. Be sure to look specifically at issues called out in the UX Review.
  • Execute the improvements!
