Question

我长期以来一直在解决以下问题，但根本无法解决。我尝试使用smack for Android通过xmpp进行文件传输，代码如下：

fTManager = FileTransferManager.getInstanceFor(connection);
            fTManager.addFileTransferListener(new FileTransferListener() {
                @Override
                public void fileTransferRequest(FileTransferRequest fileTransferRequest) {
                    String requerstor = fileTransferRequest.getRequestor();
                    try {
                        IncomingFileTransfer transfer = fileTransferRequest.accept();
                        transfer.recieveFile(new File(getExternalFilesDir(null), transfer.getFileName()));

                        bufferedReader = new BufferedReader(new FileReader(new File(getExternalFilesDir(null), transfer.getFileName())));
                        String line;
                        while ((line = bufferedReader.readLine()) != null)
                            Log.i("Line", "LINE " + line);
                        while (!transfer.isDone()) {
                            Thread newThread = new Thread();
                            Log.i("FileTransferManager", "File transfer is " + String.format("%1$,.2f", transfer.getProgress() * 100) + "% complete.");
                            try {
                                newThread.sleep(1000);
                            } catch (InterruptedException e) {e.printStackTrace();}
                        }

                        if (transfer.isDone())
                            Log.i("FileTransferManager", "Transfer status is:" + transfer.getStatus());
                        if (transfer.getError() != null)
                            Log.i("FileTransferManager", "Transfer error occurred:" + transfer.getError().getMessage());
                        if(transfer.getException() != null)
                            transfer.getException().printStackTrace();
                        }
                     catch (SmackException e) {e.printStackTrace();}
                     catch (IOException e) { e.printStackTrace();}

如果我收到文件传输请求，则可以显示请求者和文件名。但是如果transfer.recieveFile(new File(getExternalFilesDir(null), transfer.getFileName()));

应该执行

发生以下错误：

我正在使用smack-4.1.0-rc4。有人知道我的线索吗？我很感激一些建议。
