audio playback error - audio

Question

I'm trying to record an audio file and play it, but I'm getting en error: Locator does not reference a valid media file. What am I missing?
here is my code of saving audio file:
//Stop recording, capture data from the OutputStream,
//close the OutputStream and player.
_rcontrol.commit();
_data = _output.toByteArray();
_output.close();
_player.close();
isRecording = 0;
try {
FileConnection fc = (FileConnection)Connector.open("file:///store/home/user/Audio.mp3");
// If no exception is thrown, then the URI is valid, but the file may or may not exist.
if (!fc.exists()) {
fc.create(); // create the file if it doesn't exist
}
OutputStream outStream = fc.openOutputStream();
outStream.write(_data);
outStream.close();
fc.close();
System.out.println("audio size: "+_data.length);
I can see in log, that my audio file has some length (about 5000 after 3-4 seconds of recording)
here is my code where i'm trying to play it:
FileConnection fc = (FileConnection)Connector.open("file:///store/home/user/Audio.mp3");
// If no exception is thrown, then the URI is valid, but the file may or may not exist.
if (fc.exists()) {
_player = Manager.createPlayer("file:///store/home/user/Audio.mp3");
_player.realize();
_player.prefetch();
if (_player.getMediaTime() == _player.TIME_UNKNOWN) {
System.out.println("zero audio doration");
}
else {
System.out.println("audio doration: "+_player.getMediaTime());
}
_player.start();
}
fc.close();
