TrackMySleepQuality - Solution Code for 6.2 Coroutines codelab
==============================================================
Solution code for Android Kotlin Fundamentals Codelab 6.2 Coroutines
Introduction
------------
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.
This app:
* Extends the TrackMySleepQuality app to collect, store, and display data in and from the database.
* Uses coroutines to run long-running database operations in the background.
* Uses LiveData to trigger navigation and showing of a snackbar.
* Uses LiveData to enable and disable buttons.
Pre-requisites
--------------
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.
Getting Started
---------------
1. Download and run the app.

TrackMySleepQuality - Final Code for 6.3 Recording Quality & Button States
============================================================================
Solution code for Android Kotlin Fundamentals Codelab 6.3 Recording Quality & Button States
Introduction
------------
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:
* Extended the TrackMySleepQuality app to collect a quality rating, add it to the database and display the result.
* Usedd LiveData to trigger showing of a snackbar.
* Use LiveData to enable and disable buttons.
Pre-requisites
--------------
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.
Getting Started
---------------
1. Download and run the app.
