老兄只需复制并粘贴以下代码，
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);
}
catch (Exception e) {
Log.e("", e.getMessage());
}
if(transfer.getStatus().equals(Status.error)) {
Log.e("ERROR!!! ", transfer.getError() + "");
}
if(transfer.getException() != null) {
transfer.getException().printStackTrace();
}
}
handler.post(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
String xMsg = textViewSent.getText().toString();
String newMessage = "File Received at "+file.getAbsolutePath();
textViewSent.setText("\n"+xMsg+"\n"+newMessage);
}
});
}
catch (Exception e) {
e.printStackTrace();
}
};
}.start();
}
});
}

没有看到您的代码很难评估问题。但是，我最初遇到了与您相同的问题，因为我使用的是InputStream stream = transfer.recieveFile();。这是使用transfer.recieveFile(new File(getExternalFilesDir(null), transfer.getFileName()));修复的。尝试添加像这样的监听器......
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();
}
}
});

bytestream transfer method失败，因为只配置了本地（127.0.0.1）流主机。 in-band bytestream因为另一方不支持IBB而失败。
