Problem with Audio.loadFromRemoteUrl in Android

[csacchetti]

I'm doing podcast app. I am very happy with this plug-in. But I encountered a strange problem with the Audio.loadFromRemoteUrl function in Android. While with iOS it works perfectly, when I try to download the .mp3 audio file, from Android, I have an error that I report below. I don't understand what it can depend on. I added in the Manifest
"uses-permission android: name = "android.permission.INTERNET"
but this is not the problem because just before I always download the xml file from the server that provides me with the list of audio files. It seems like a media problem. If anyone can help me I would be very grateful.
Thanks in advance
