Browses media content offered by a `https://developer.android.com/reference/kotlin/androidx/media/MediaBrowserServiceCompat`.

The app targeting API level 30 or higher must include a `<queries>` element in their manifest to connect to a media browser service in another app. See the following example and [this guide](https://developer.android.com/training/package-visibility) for more information.

```kotlin
<!-- As an intent action -->
<intent>
  <action android:name="android.media.browse.MediaBrowserService" />
</intent>
<!-- Or, as a package name -->
<package android:name="package_name_of_the_other_app" />
```

This object is not thread-safe. All calls should happen on the thread on which the browser was constructed. All callback methods will be called from the thread on which the browser was constructed.

Queries for information about the media items that are contained within the specified id and subscribes to receive updates when they change.

The list of subscriptions is maintained even when not connected and is restored after the reconnection. It is ok to subscribe while not connected but the results will not be returned until the connection completes.

If the id is already subscribed with a different callback then the new callback will replace the previous one and the child data will be reloaded.

| Parameters |
|---|---|
| `parentId: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-string/index.html` | The id of the parent media item whose list of children will be subscribed. |
| `callback: https://developer.android.com/reference/kotlin/android/support/v4/media/MediaBrowserCompat.SubscriptionCallback` | The callback to receive the list of children. |
