So the solution Define the referenced value in the values directory

Solution:
Register MediaButtonReceiver in Manifest

<receiver android:name="androidx.media.session.MediaButtonReceiver" >
    <intent-filter>
        <action android:name="android.intent.action.MEDIA_BUTTON" />
    </intent-filter>
</receiver>
