Android Room Database explained with Code! | Android Jetpack

Kotlin Tutorial on Android Room Database!

As part of Android Jetpack, Room provides an abstraction layer on top of the SQLite database. While SQLite offers powerful, low-level access, it comes with a few drawbacks: you don't get compile-time query check, and, being a low-level API, it is error-prone to use and requires a lot of boilerplate code. Room, in contrast, has a much easier-to-use API, which makes heavy use of Annotations to keep your files simple and easy to maintain. It also offers compile-time query checks and high testability. Furthermore, Room supports observable queries, which helps with reactive programming. Finally, you won't be blocking the UI thread with Room because it throws an exception if you try to access the database from the UI thread.

Informative don't stop uploading android with kotlin videos ..

So well explained! Can you make a follow-up video showing how a user interface would connect with this database in a sample app?
