Insert, Select with Room Database (MVVM Compatible) : Android Room Database - 6
In this video, we dive into the implementation of Room Database in an Android application. In the previous video we have setup two essential methods: FetchAndInsertAll and GetAllCountries. We then connect the remaining code to load and display countries on the screen.
Next, we implement the ViewModel and composable components, ensuring seamless integration with the repository. The video covers creating a Kotlin class for CountryViewModel, handling mutable states, and initializing data access objects, repositories, and ViewModelFactory. We also demonstrate using coroutines, and inspecting the database to debug issues.
By the end of this tutorial, you'll understand how to fetch, insert, and render data using Room Database in an Android app. We'll also provide tips on creating and managing ViewModels and using the ViewModelProvider.Factory.
Stay tuned for the next video, where we'll debug and fix issues related to database entries. Don't forget to like, comment, share, and subscribe for more Android development tutorials!
