Starter code for Android Kotlin Fundamentals Codelab 6.3 Recording Quality & Button States
TrackMySleepQuality is an app for recording sleep data for each night. You can record a start and stop time, assign a quality rating, and clear the database.
In this codelab, working from this starter app, you will:
- Extend the TrackMySleepQuality app to collect a quality rating, add it to the database and display the result.
- Use LiveData to trigger showing of a snackbar.
- Use LiveData to enable and disable buttons.
You should be familiar with:
- Navigating between fragments, and using safeArgs to pass data between fragments.
- View models, view model factories, Transformations, and LiveData and their observers from the preceding Architecture Components codelab[LINK].
- How to create a Room database, create a DAO, and define entities.
- How to use coroutines for database interactions and other long-running tasks.
- Download and run the app.
