 Continuous Integration (CI) is a fundamental practice in modern software development. For an Android app like "My-Tasks," a CI workflow can automatically build and test your code every time you open a pull request, ensuring that new changes don't break existing functionality.
 
 This codelab will guide you through completing a "skeleton" GitHub Actions workflow file. You will implement the `TODO` items to build a complete, functioning CI pipeline.
