Android: How to get image using MediaMetadataRetriever?

Question

I'm developing a music player on android and i get a bug that i dont know why. I think I do right but it does not work.

I did search a lot of MediaMetadataRetriever, but I still don't see what my problem is.

I use MediaMetadataRetriever to get infomation about my song. Everything work fine but getEmbeddedPicture(). I get this message whenever getEmbeddedPicture called: 11-15 13:36:11.101: E/MediaMetadataRetrieverJNI(460): getEmbeddedPicture: Call to getEmbeddedPicture failed.

I know this method only called after setDataSource called, and I did it, but I still get that bug ( of course, my song has image in it and I'm using android 2.3.3).

This is the code:

mediaInfo.setDataSource(filePath);//filePath is correct.
byte[] img = mediaInfo.getEmbeddedPicture();//cause error
if (img != null)
    imgAlbum.setImageBitmap(BitmapFactory.decodeByteArray(img, 0,img.length));

Thanks.

The following should work:

MediaMetadataRetriever retriever = new MediaMetadataRetriever();
retriever.setDataSource(filePath);
byte[] art = retriever.getEmbeddedPicture();

if( art != null ){
    imgAlbum.setImageBitmap( BitmapFactory.decodeByteArray(art, 0, art.length));
}
else{
    imgAlbum.setImageResource(R.drawable.no_image);
}
