How to play sound with custom volume? (Xamarin.Forms Android)

Question

If my android phone's volume is set to 20%, but in my app, I want to play sound with volume 100%, how to do this?
I try:
public void PlaySound(int id)
{
var mediaPlayer = MediaPlayer.Create(MainActivity.Instance.ApplicationContext, id);
float maxVolume = 100;
float currVolume = 100;
float log1 = (float)(Math.Log(maxVolume - currVolume) / Math.Log(maxVolume));
mediaPlayer.SetVolume(log1, log1);
mediaPlayer.Start();
mediaPlayer.Completion += (sender, e) =>
{
//mediaPlayer.Reset();
mediaPlayer.Release();
};
}

But the sound still playing with system volume setting...

Hello,​

Welcome to our Microsoft Q&A platform!

The MediaPlayer API is recommended for balancing the output of audio streams within an application. If you want to change the user settings of volume, please use AudioManager.setStreamVolume(int, int, int) method instead.

Here is the related doc, you could refer to it:
https://developer.android.com/reference/android/media/MediaPlayer.html#setVolume(float,%20float)
