Stock Hawk is my submission for Project 3 in Udacity's Associate Android Developer Fast Track course supported by Google. My task was to build upon starting_state, fix bugs and add new functionality.
Project Overview:
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.
Why this Project?
Stock Hawk gives you an opportunity to diagnose problems and 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.
To pass this project app has to meet specifications. This project was reviewed by Udacity code reviewer and was graded positively as it met the requested specifications.
