Answer 1

Nếu không thấy mã của bạn khó đánh giá được sự cố. Tuy nhiên, ban đầu tôi có cùng một vấn đề với bạn vì tôi đã sử dụng InputStream stream = transfer.recieveFile();. Điều này đã được sửa bằng cách sử dụng transfer.recieveFile(new File(getExternalFilesDir(null), transfer.getFileName()));. Thử thêm người nghe như thế này ...

fileTransferManager.addFileTransferListener(new FileTransferListener() { 
    @Override 
    public void fileTransferRequest(FileTransferRequest request) { 
     try { 
      IncomingFileTransfer transfer = request.accept(); 
      transfer.recieveFile(new File(getExternalFilesDir(null), transfer.getFileName())); 
      String line; 
      BufferedReader br = new BufferedReader(new FileReader(new File(getExternalFilesDir(null), transfer.getFileName()))); 
      while ((line = br.readLine()) != null) { 
       System.out.println(line); 
      } 
     } catch (Exception e) { 
       e.printStackTrace(); 
     } 
    } 
});

Các bytestream transfer method failes, bởi vì chỉ có một địa phương (127.0.0.1) cấu hình streamhost. in-band bytestream không thành công vì bên kia không hỗ trợ IBB.

Bạn nên:

• Configure một streamhost hợp lệ mà đóng vai trò như một proxy (XEP-65 Section 6 "Mediated Connection")
• Enable IBB nếu có thể

Answer 3

Dude Chỉ cần sao chép và dán đoạn mã sau,

private void receiveFile(XMPPConnection connection2) { 
    // TODO Auto-generated method stub 
    if(connection2 != null){ 
     ServiceDiscoveryManager sdm =  ServiceDiscoveryManager.getInstanceFor(connection2); 
     if (sdm == null){ 
      sdm = new ServiceDiscoveryManager(connection2); 
     } 
     sdm.addFeature("http://jabber.org/protocol/disco#info"); 
     sdm.addFeature("jabber:iq:privacy"); 
     FileTransferManager manager = new FileTransferManager(connection2); 

     manager.addFileTransferListener(new FileTransferListener() { 

      public void fileTransferRequest(final FileTransferRequest request) { 
       new Thread(){ 

        @Override 
        public void run() { 
         IncomingFileTransfer transfer = request.accept();       
         File mf = Environment.getExternalStorageDirectory();     
         final File file = new File(mf.getAbsoluteFile() +"/"+ transfer.getFileName()); 
         try{ 
          transfer.recieveFile(file); 
          while(!transfer.isDone()){ 
           try{ 
            Thread.sleep(1000); 
           } 
           catch (Exception e) { 
            Log.e("", e.getMessage()); 
           } 
           if(transfer.getStatus().equals(Status.error)) { 
            Log.e("ERROR!!! ", transfer.getError() + ""); 
           } 
           if(transfer.getException() != null) { 
            transfer.getException().printStackTrace(); 
           } 
          } 
          handler.post(new Runnable() { 

           @Override 
           public void run() { 
            // TODO Auto-generated method stub 
            String xMsg = textViewSent.getText().toString(); 
            String newMessage = "File Received at "+file.getAbsolutePath(); 
            textViewSent.setText("\n"+xMsg+"\n"+newMessage); 
           } 
          }); 
         } 
         catch (Exception e) { 
          e.printStackTrace(); 
         }       
        }; 
        }.start(); 
      } 
     }); 
    } 

Hãy nhớ bỏ phiếu ...
