What is ComposeViewAdapter used for in Jetpack Compose?

I have a simple composable function in com.example.Example.kt:

@Preview
@Composable fun ExampleComposable() {
    Text("Hello")
}

I tried to use ComposeViewAdapter like below:

<androidx.compose.ui.tooling.ComposeViewAdapter
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:composableName="com.example.ExampleKt" />

Android Studio does not show any preview of the composable in the design pane.

Also, how is ComposeViewAdapter different from androidx.compose.ui.platform.ComposeView?

Example.kt file can have many composables, you need to specify the composable name:

<androidx.compose.ui.tooling.ComposeViewAdapter
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:composableName="com.example.ExampleKt.ExampleComposable" />
