Android file transfer with 4.1.0-rc4/rc3 Error in execution

Hello,

I’ve been struggeling with the following problem for a long time, but couldn’t solve it at all. Im trying a file transfer via xmpp using smack for Android with the following code:

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();}

As

transfer.recieveFile(new File(getExternalFilesDir(null), transfer.getFileName()));

is reached I am getting the following error:
