I understand you're using VXG Media Player for your application. VXG Media Player is a third-party library for video playback in Android. Let's adapt the previous implementation to work with VXG Media Player. Here's a basic implementation that integrates VXG Media Player with a media notification:
First, make sure you have the VXG Media Player SDK integrated into your project according to their documentation.
Here's a modified version of the code that should work with VXG Media Player:
kotlinCopyimport android.app.*
import android.content.Intent
import android.os.Build

import androidx.core.app.NotificationCompat
import androidx.media.app.NotificationCompat.MediaStyle

        when (intent?.action) {
            "PLAY" -> playMedia()
