How to get the album art of a media file in Xamarin? - xamarin.android

Question

I've been searching for a couple of days on how to get the album art for a song (or a frame capture of a video) from a file path. All I could find is things related to Mediastore like this answer where it requires getting the album ID of the file.
Cursor cursor = getContentResolver().query(MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI,
new String[] {MediaStore.Audio.Albums._ID, MediaStore.Audio.Albums.ALBUM_ART},
MediaStore.Audio.Albums._ID+ "=?",
new String[] {String.valueOf(albumId)},
null);
if (cursor.moveToFirst()) {
String path = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Albums.ALBUM_ART));
// do whatever you need to do
}
But I can't find a guid on how it works, how can pass the file to Mediastore or how can I get the album ID of the media or anything... Currently I get the media information using MediaMetadataRetriever but I can't find a way to get the album art or a video thumbnail of a media file using it...
** Update :-
If Mediastore must be used to get the media files in the first place before using it to get their data, I can implement it instead of what I'm currently doing (Currently I iterate the device files to get the supported files) and it can be a better option as Mediastore supports getting data from external storages as well.
Any help is appreciated.

If using MediaMetadataRetriever , you can have a try with follow sample code :
private void loadingCover(string mediaUri)
{
MediaMetadataRetriever mediaMetadataRetriever = new MediaMetadataRetriever();
mediaMetadataRetriever.SetDataSource(mediaUri);
byte[] picture = mediaMetadataRetriever.GetEmbeddedPicture();
Android.Graphics.Bitmap bitmap = BitmapFactory.DecodeByteArray(picture, 0, picture.Length);
musicCover.SetImageBitmap(bitmap);
}
In addition , not forgatting to add permission :
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
Invoke it as follow :
File file = new File("/storage/sdcard/Movies/music1.mp4");
if (file.Exists())
{
loadingCover(file.AbsolutePath);
}
