Android 文件传输无法通过 XMPP 和 OpenFire 工作

Question

问题:无法接收通过 XMPP 和 OpenFire 服务器发送到我的 android 应用程序的文件。我可以成功发送文件。我使用的 asmack jar 是 asmack-jse-buddycloud-2010.12.11.jar

代码:

    connConfig = new ConnectionConfiguration("beta.myCompany.co.uk", 5222);
    connConfig.setSASLAuthenticationEnabled(true);
    try {
        connect("username", "password");
    } catch (Exception e) {
        e.printStackTrace();
    }

    ServiceDiscoveryManager sdm = ServiceDiscoveryManager.getInstanceFor(connection);
    if(sdm == null)
        sdm = new ServiceDiscoveryManager(connection);

    fileTransferManager = new FileTransferManager(connection);
    FileTransferNegotiator.setServiceEnabled(connection, true);

fileTransferManager.addFileTransferListener(new FileTransferListener() {
    @Override
    public void fileTransferRequest(FileTransferRequest request) {
        IncomingFileTransfer transfer = request.accept();
        try {
            FileOutputStream fos = openFileOutput(request.getFileName(), Context.MODE_PRIVATE);
            InputStream stream = transfer.recieveFile();//THIS FAILS!
            fos.write(IOUtils.toByteArray(stream));
            fos.close();    
        } catch (Exception e) {
            e.printStackTrace();
        }
}

错误(如果文件是通过 Spark 发送的):

Error in execution: -- caused by: java.util.concurrent.ExecutionException: No response from file transfer initiator:

错误(如果文件是通过 Adium 发送的):

java.util.concurrent.ExecutionException: Could not establish socket with any provided host: item-not-found(404) Could not establish socket with any provided host

错误(如果文件是通过我的应用程序的另一个实例发送的):

Error in execution: -- caused by: java.util.concurrent.ExecutionException: -- caused by: No response from remote client:

我的日志:(尝试从 Spark 接收文件时)

看来我正在发送这个错误! (没有收到)。为什么会这样？

Answer 1

使用

transfer.receiveFile(myLocalFile);

代替

InputStream stream = transfer.receive();

您正在阻塞 PacketReader 线程。第一种方法将产生它自己的线程来读取构成正在传输的文件部分的特定数据包。如果您使用第二种方法，则必须生成自己的线程来执行实际的文件读写。
