As a platform matures, the app's codebase is getting bigger. In these big codebases, there is legacy code all over the place. Working on that environment is highly unpleasant, without applying the right strategies to refactor this smelly code.
Attend this class to first learn the design principles, patterns and how to apply them on Android and the payoff. Second, you will learn how you could apply these to legacy code. Testing will play a huge role in this.
The class will be really pragmatic, and the idea is to show a pattern and how to apply it to a real piece of code. You will see principles and patterns and how to apply them on Android. Having a strong test suite is key for refactoring and improving your code and will give you the ability to make changes faster without breaking features.
