在android asmack中发送文件的最佳方式是什么

public void send()
{

configureProviderManager(connection);

FileTransferNegotiator.setServiceEnabled(connection, true);
FileTransferManager manager = new FileTransferManager(connection);
OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer("xxxxx@jabber.ccc.de/Smack");

File file = new File("/sdcard/DCIM/Camera/1385869353956.jpg");
try {
    Log.d("file sending",file.getAbsolutePath()+" "+file.getName());
    configureProviderManager(connection);
   transfer.sendFile(file, "test_file");
} catch (XMPPException e) {
   e.printStackTrace();
}

while(!transfer.isDone()) {
       if(transfer.getStatus().equals(Status.error)) {
          System.out.println("ERROR!!! " + transfer.getError());
       } else if (transfer.getStatus().equals(Status.cancelled)
                        || transfer.getStatus().equals(Status.refused)) {
          System.out.println("Cancelled!!! " + transfer.getError());
       }
       try {
          Thread.sleep(1000L);
       } catch (InterruptedException e) {
          e.printStackTrace();
       }
    }

    if(transfer.getStatus().equals(Status.refused))
             System.out.println("refused  " + transfer.getError());
    else if( transfer.getStatus().equals(Status.error))
         System.out.println(" error " + transfer.getError());
    else if(transfer.getStatus().equals(Status.cancelled))
       System.out.println(" cancelled  " + transfer.getError());
    else
       System.out.println("Success");

您可以根据自己的要求进行更改。

public class MyFileTransfer  extends SmackTest<XMPPTCPConnection> {

    public static void main(String args[]) throws Exception {
        SmackTest<XMPPTCPConnection> test = new MyFileTransfer();
        test.runTest();
    }

    private static final byte[] dataToSend = StringUtils.randomString(1024 * 4 * 3).getBytes();
    private static byte[] dataReceived;

    @Override
    protected void runTestSubclass() throws SmackException, IOException,
            XMPPException, InterruptedException, KeyManagementException, NoSuchAlgorithmException {
        FileTransferNegotiator.IBB_ONLY = true;
        XMPPTCPConnectionConfiguration.Builder conf = XMPPTCPConnectionConfiguration.builder();
        conf.setServiceName(SERV);
        conf.setUsernameAndPassword(USER, PASS);
        conf.setSecurityMode(SecurityMode.disabled);
        conf.setCompressionEnabled(true);
        TLSUtils.acceptAllCertificates(conf);
        conf.setResource("sender");

        connection = new XMPPTCPConnection(conf.build());
        connection.connect();
        connection.login();

        conf.setResource("receiver");
        XMPPTCPConnection connection2 = new XMPPTCPConnection(conf.build());
        connection2.connect();
        connection2.login();

                try {
                    InputStream is = ift.recieveFile();
                    ByteArrayOutputStream os = new ByteArrayOutputStream();

                    os.flush();
                    dataReceived = os.toByteArray();
                } catch (SmackException | IOException | XMPPErrorException e) {
                    e.printStackTrace();
                }
                if (Arrays.equals(dataToSend, dataReceived)) {
                    System.out.println("Received data matches send data. \\o/");
                } else {
                    System.err.println("Recieved data DOES NOT match send data. :(");
                }
            }
        });

        OutgoingFileTransfer oft = ftm1.createOutgoingFileTransfer(XmppStringUtils.completeJidFrom(USER, SERV, "receiver"));
        oft.sendStream(new ByteArrayInputStream(dataToSend), "hello.txt", dataToSend.length, "A greeting");
        outerloop: while (!oft.isDone()) {
            switch (oft.getStatus()) {
                case error:

                    break outerloop;
                default:

                    break;
            }
            Thread.sleep(1000);

        connection.disconnect();
        connection2.disconnect();
