Answer 1

प्राप्त अपने कोड अपनी हार्ड देखकर समस्या का मूल्यांकन करने के बिना। हालांकि, मुझे मूल रूप से आपके जैसा ही समस्या थी क्योंकि मैं InputStream stream = transfer.recieveFile(); का उपयोग कर रहा था। यह transfer.recieveFile(new File(getExternalFilesDir(null), transfer.getFileName())); का उपयोग कर तय किया गया था। आपके लॉग से इस तरह श्रोता जोड़ने का प्रयास करें ...

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(); 
     } 
    } 
});

bytestream transfer method failes, एक स्थानीय (127.0.0.1) streamhost कॉन्फ़िगर किया गया। in-band bytestream विफल रहता है क्योंकि दूसरी पार्टी आईबीबी का समर्थन नहीं करती है।

आप करना चाहिए: एक वैध streamhost कि प्रॉक्सी के रूप में कार्य करता है

• कॉन्फ़िगर (XEP-65 Section 6 "Mediated Connection")
• सक्षम करें IBB यदि संभव हो तो

Dude बस कोड को कॉपी करके निम्न पेस्ट,

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(); 
      } 
     }); 
    } 

कृपया वोट देना याद रखें ...
