[TIMOB-13150] Android: AudioPlayer.start() freezes UI thread

*Problem description* AudioPlayer.start() freezes the user interface on Android for several seconds (9 seconds and more) until playback starts. I would expect it to be asynchronous (there are events that all one to know what happens...). Or at least it should also have a startAsync(). The url of the AudioPlayer is set to a remote MP3/SHOUTcast stream. *Test case*

var win = Ti.UI.createWindow({
	backgroundColor : "#FFF"
});

var audioPlayer = Titanium.Media.createAudioPlayer({
	allowBackground : true
});
audioPlayer.setUrl('http://broadcast.infomaniak.net:80/energyzuerich-high.mp3');
var s = new Date().getTime();
audioPlayer.start();
audioPlayer.stop();
alert("time required: " + (new Date().getTime() - s));

win.open();
