* Metadata:
* Image:
* DRM:
* Work around a `NoSuchMethodError` which can be thrown by the `MediaDrm`
framework instead of `ResourceBusyException` or
`NotProvisionedException` on some Android 14 devices
([#1145](https://github.com/androidx/media/issues/1145)).
* DataSource:
* Implement support for `android.resource://package/id` raw resource URIs
where `package` is different to the package of the current application.
