What is ktx

As an example, assume a database with a small list of users. In your app, you load the database into memory and then display user data in your UI. To achieve this, you might use RxJava. The Room Jetpack component can retrieve the user list as a Flowable. In this scenario, you must also manage the Rx publisher subscription across the life of your fragment or activity.

With LiveDataReactiveStreams , however, you can benefit from RxJava and its rich set of operators and work-scheduling capabilities while also working with the simplicity of LiveData , as shown in the following example:.

Here are a couple of examples where Room now uses coroutines. The first example uses a suspend function to return a list of User objects, while the second utilizes Kotlin's Flow to asynchronously return the User list.

Note that when using Flow , you're also notified of any changes in the tables you're querying. Here's an example of using the transaction extension to perform a database transaction:. The CoroutineScope is bound to Dispatchers. Main and is automatically cancelled when the ViewModel is cleared.

You can use viewModelScope instead of creating a new scope for each ViewModel. As an example, the following viewModelScope function launches a coroutine that makes a network request in a background thread.

The library handles all of the setup and corresponding scope clearing:. For example, if you wanted to build a simple CoroutineWorker to perform some network operations, you can do the following:.

Here's an example that suspends the Operation that's returned by enqueue :. For more information, see the following topics:.
