无法使用asmack传输文件

Question

我创建了一个聊天应用程序，我正在使用asmack lib。 我正在尝试在同一个XMPP服务器上的两个客户端（Android应用程序）之间传输文件，但是我得到了一个奇怪的错误。

当我尝试发送文件时，传出文件传输开始，目标客户端收到请求，但源客户端无法进一步进行传输协商。我总是陷入'谈判转移'......

通过从移动应用程序向桌面应用程序（例如Spark IM Client）发送文件，只能成功传输文件。

知道造成这种情况的原因是什么？

发送文件：

OutgoingFileTransfer lTransfer = mFileTransferManager.createOutgoingFileTransfer(mJid+"/"+resource);
// Send the file
try {
    lTransfer.sendFile(new File(filePath),mMessage);
    } catch (XMPPException e) {
    Log.e(TAG,"Error sending file");
}

while(!lTransfer.isDone()){
    if(lTransfer.getStatus().equals(FileTransfer.Status.error)) {
        Log.e(TAG,"ERROR!!! " + lTransfer.getError());
        } else {
        Log.i(TAG, "Status:"+lTransfer.getStatus().toString());
        Log.i(TAG, "Progress:"+String.valueOf(lTransfer.getProgress()));
    }
    try {
        Thread.sleep(1000);
} catch (InterruptedException ignored) { }
}

if(lTransfer.getStatus().equals(FileTransfer.Status.refused)
|| lTransfer.getStatus().equals(FileTransfer.Status.error)
|| lTransfer.getStatus().equals(FileTransfer.Status.cancelled)){
    Log.e(TAG,"refused cancelled error " + lTransfer.getError());
    return false;
    } else {
    Log.i(TAG,"Sucesss");
    return true;
}

mFileTransferManager.addFileTransferListener(new FileTransferListener() {
    public void fileTransferRequest(FileTransferRequest request) {
        String path = "/sdcard/"+ request.getFileName();
        IncomingFileTransfer lTransfer = fileTransferRequest.accept();
        lTransfer.recieveFile(new File(path));
        double percents = 0.0;
        while (!lTransfer.isDone()) {
            if (lTransfer.getStatus().equals(FileTransfer.Status.in_progress)) {
                percents = ((int) (lTransfer.getProgress() * 10000)) / 100.0;
                Log.d(TAG, "File transfer: " + newFile.getAbsolutePath() + " - " + percents + "%");
                } else if (lTransfer.getStatus().equals(FileTransfer.Status.error)) {
                Log.e(TAG, "ERROR in transfer");
                return;
            }
            Thread.sleep(1000);
        }
        if (lTransfer.getStatus().equals(FileTransfer.Status.complete)) {
            Log.i(TAG, "File transfert: " + newFile.getAbsolutePath() + " - 100%");
            } else {
            Log.e(TAG, "ERROR in transfer");
        }
    });
