El método de transferencia de bytestream failes, porque solo hay un streamhost local (127.0.0.1) configurado. El bytestream de banda se descompone porque la otra parte no admite IBB.

Debieras:

• Configure un streamhost válido que actúe como proxy ( XEP-65 Sección 6 "Conexión mediada" )
• Habilitar IBB si es posible

Answer 2

Sólo copie y pegue el siguiente código,

private void receiveFile(XMPPConnection connection2) {
    // TODO Auto-generated method stub
    if(connection2 != null){
        ServiceDiscoveryManager sdm =      ServiceDiscoveryManager.getInstanceFor(connection2);
        if (sdm == null){
            sdm = new ServiceDiscoveryManager(connection2);
        }
        sdm.addFeature("http://jabber.org/protocol/disco#info");
        sdm.addFeature("jabber:iq:privacy");
        FileTransferManager manager = new FileTransferManager(connection2);

        manager.addFileTransferListener(new FileTransferListener() {

            public void fileTransferRequest(final FileTransferRequest request) {
                new Thread(){

                    @Override
                    public void run() {
                        IncomingFileTransfer transfer = request.accept();                           
                        File mf = Environment.getExternalStorageDirectory();                
                        final File file = new File(mf.getAbsoluteFile() +"/"+ transfer.getFileName());
                        try{
                            transfer.recieveFile(file);
                            while(!transfer.isDone()){
                               try{
                                  Thread.sleep(1000);
                               }

                               if(transfer.getStatus().equals(Status.error)) {
                                  Log.e("ERROR!!! ", transfer.getError() + "");
                               }
                               if(transfer.getException() != null) {
                                  transfer.getException().printStackTrace();
                               }
                            }
                            handler.post(new Runnable() {

                                    textViewSent.setText("/n"+xMsg+"/n"+newMessage);
                                }

Sin ver su código es difícil evaluar el problema. Sin embargo, originalmente tuve el mismo problema que tú porque estaba usando InputStream stream = transfer.recieveFile(); . Esto se solucionó utilizando transfer.recieveFile(new File(getExternalFilesDir(null), transfer.getFileName())); . Intenta agregar al oyente de esta manera ...

fileTransferManager.addFileTransferListener(new FileTransferListener() {
    @Override
    public void fileTransferRequest(FileTransferRequest request) {
        try {
             IncomingFileTransfer transfer = request.accept();
             transfer.recieveFile(new File(getExternalFilesDir(null), transfer.getFileName()));
             String line;
             BufferedReader br = new BufferedReader(new FileReader(new File(getExternalFilesDir(null), transfer.getFileName())));
             while ((line = br.readLine()) != null) {
                 System.out.println(line);
             }
        } catch (Exception e) {
                e.printStackTrace();
        }
    }
});
