I am working on chatting application and i have to implement file transfer using smack api. I am able to Connect to the open fire server and can also chat with another client.But i dont know how to implement file transfer..I have found a code snippet but i am not ableto send it using that also.Following is the code snippet i am using:

public void SendFile(final String Receiver, final String Directory) {
        Thread thread = new Thread() {
            public void run() {
            ServiceDiscoveryManager sdm = ServiceDiscoveryManager
            .getInstanceFor(connection);
            if (sdm == null)
                sdm = new ServiceDiscoveryManager(connection);
            sdm.addFeature("http://jabber.org/protocol/disco#info");
            sdm.addFeature("jabber:iq:privacy");
            // Create the file transfer manager
            FileTransferManager manager = new FileTransferManager(
                    connection);
            FileTransferNegotiator
            .setServiceEnabled(connection, true);

            // Create the outgoing file transfer
            OutgoingFileTransfer transfer = manager
            .createOutgoingFileTransfer("alok@chd-akumar4" );
            Log.i("transfere file", "outgoingfiletransfere is created");
            try {
                OutgoingFileTransfer.setResponseTimeout(30000);
                transfer.sendFile(new File(Directory), "Description");
                Log.i("transfere file", "sending file");
                while (!transfer.isDone()) {
                    try {
                        Thread.sleep(1000);
                        Log.i("transfere file", "sending file status "
                                + transfer.getStatus() + "progress: "
                                + transfer.getProgress());
                        if (transfer.getStatus() == org.jivesoftware.smackx.filetransfer.FileTransfer.Status.error) {
                            transfer.cancel();
                            Log.e("","EEEEEERRRRRRRROOORRRRR");
                            break;
                        }
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        Log.e("aaaaaaaaaaaaaaa","aaaa"+e);
                        e.printStackTrace();
                    }
                }
            } 
            catch (XMPPException e) {
                // TODO Auto-generated catch block
                Log.e("aaaaaaaaaaaaaaa","aaaa"+e);
  开发者_开发百科              e.printStackTrace();
            }
            Log.i("transfere file", "sending file done");
        }
        };
        thread.start();
    }

can any one help me finding the solution..

If you are using version 3.2.x, there is a known problem with file transfer. Try using 3.1 to see if it fixes your problem.

Now we have 4.1.0 with updated API's.

FileTransferRequest and StreamInitiation makes it more easy now.

Please check with latest Smack version.
