Fix existing code of playing background music and video in Android Studio

I am looking for a skilled Android developer who can fix the existing code in Android Studio for playing background music and video. Currently, both the background music and video are not playing. The current implementation code uses SimpleExoPlayer and PlayerView. One possiblity is to replace the usage of SimpleExoPlayer with ExoPlayer or any better media player. We are using remote URL for the media source.

Requirements:
- Experience with Android Studio, specifically version Giraffe | 2022.3.1
- Proficiency in Java and Android development
- Strong understanding of media playback in Android
- Knowledge of troubleshooting and debugging techniques
- Attention to detail and ability to identify and resolve issues

The goal of this project is to ensure that the background music and video play properly in the Android application. The code needs to be fixed so that both the background music and video can be played without any issues.

If you have previous experience with similar projects and can confidently fix the code to make the background music and video work properly, please submit your proposal.
