在回复超时内未收到任何响应。超时时间为30000毫秒（约30秒）。在等待流启动时

Question

我正在开发Smack 4.2.0版本。我遇到了通过smack接收图像的问题，一切正常，同时发送短信和接收短信。我在回收图像时遇到异常

在回复超时内未收到任何回复。超时时间为30000毫秒（约30秒）。在等待流启动时

我已按照文档

我已经搜索过，我找到了增加数据包流超时但仍面临同样问题的解决方案

图片接收代码段

private void RecieveIncommingFiles() {
        try{
            if (mConnection != null){
                FileTransferManager manager = FileTransferManager.getInstanceFor(mConnection);
                manager.addFileTransferListener(new FileTransferListener() {
                    @Override
                    public void fileTransferRequest(FileTransferRequest request) {
                        IncomingFileTransfer transfer = request.accept();
                        try {
                            File file = new File("/storage/emulated/0/Download/" + transfer.getFileName());
                            transfer.recieveFile(file);
                            Log.d(TAG, "recieve success");
                        } catch (SmackException e) {
                            e.printStackTrace();
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                    }
                });
            }


        }catch (Exception e){
            e.printStackTrace();
        }
    }

发送图片代码段

file = new File(getRealPathFromURI(imageUri));
            // Create the file transfer manager
            if (mConnection != null){
                FileTransferManager manager = FileTransferManager.getInstanceFor(mConnection);
                // Create the outgoing file transfer
                OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer(JidCreate.entityFullFrom(recieverFullBareid));
                transfer.sendFile(file, "Image!");
                Log.d(TAG, "send success");
            }
