Question

我无法使用 asmack 接收文件，但我能够发送文件。 下面是接收文件的代码，请告诉我我做错了什么

             ServiceDiscoveryManager serv=  new ServiceDiscoveryManager(ConnectionActivity.m_connection);
    FileTransferManager manger=new FileTransferManager(ConnectionActivity.m_connection);
    manger.addFileTransferListener(new FileTransferListener(){

        @Override
        public void fileTransferRequest(FileTransferRequest request) {
            // TODO Auto-generated method stub
            Log.v("request", "accept");
            IncomingFileTransfer transfer = request.accept();
            transfer=request.accept();
            Log.v("status",transfer.getStatus()+"");
            Log.v("filename",transfer.getFileName()+"");//im able to get filename
            File file=new File(Environment.getExternalStorageDirectory()+"/off","downloaded");
            try {
                transfer.recieveFile(file);
            } catch (XMPPException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }



        }

     });

添加这个:

// //File transfer
pm.addIQProvider("si", "http://jabber.org/protocol/si",
        new StreamInitiationProvider());
pm.addIQProvider("query", "http://jabber.org/protocol/bytestreams",
        new BytestreamsProvider());
pm.addIQProvider("open", "http://jabber.org/protocol/ibb",
        new OpenIQProvider());
pm.addIQProvider("close", "http://jabber.org/protocol/ibb",
        new CloseIQProvider());
pm.addExtensionProvider("data", "http://jabber.org/protocol/ibb",
        new DataPacketProvider());
