Starter code for Android Kotlin Fundamentals Codelab 6.2 Coroutines
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, store, and display data in and from the database.
- Use coroutines to run long-running database operations in the background.
- Use LiveData to trigger navigation and showing of a snackbar.
- Use LiveData to enable and disable buttons.
You need to know:
- Building a basic user interface (UI) for an Android app, using an activity, fragments, and views.
- Navigating between fragments and using Safe Args (a Gradle plugin) to pass data between fragments.
- View models, view-model factories, and LiveData and its observers. These Architecture Components topics are covered in an earlier codelab in this course.
- A basic understanding of SQL databases and the SQLite language.
- How to create a Room database, create a DAO, and define entities, from the previous Room codelab[LINK].
- It is helpful if you are familiar with threading and multiprocessing concepts.
- Download and run the app.
