    <p>I am trying to send a file using Android bluetooth sockets. I am getting the pairing requests but unfortunately the data is not being transferred my Server side and client side is as follows:</p> <p>Server: (for my application server is receiving the data)</p> <pre><code>public void run() { super.run(); BluetoothAdapter mBtadapter = BluetoothAdapter.getDefaultAdapter(); Log.i("bluetooth Adapter", "got adapter "+ mBtadapter.getAddress()); try { Ssocket = mBtadapter.listenUsingRfcommWithServiceRecord("CardXchange", uuid); Log.i("Socket", "Socket Acquired "+ Ssocket.toString()); } catch (IOException e) { e.printStackTrace(); } while(true){ if(read_flag()==1){ try { Toast.makeText(c, "flag is eventually 1", Toast.LENGTH_LONG).show(); Ssocket.close(); } catch (IOException e) { e.printStackTrace(); } break; } try { client_socket = Ssocket.accept(); if(client_socket!=null){ //this function is used to handle the connection when sockets get connected manageConnection1(client_socket); Ssocket.close(); break; } } catch (IOException e) { e.printStackTrace(); } } Log.i("breaked ", "oh god!! out of the loop "); } //implementation of the function private void manageConnection1(BluetoothSocket client_socket2) { // TODO Auto-generated method stub int bytes; Log.i("serevr chya manage connection madhe gela", "in servers manage connection "); File file = new File("/sdcard/myfolder/received.Xcard"); try { FileOutputStream fos = new FileOutputStream(file); try { InputStream is = client_socket2.getInputStream(); while((bytes = is.read(buffer, 0, 1024))&gt;0){ fos.write(buffer, 0, 1024); } is.close(); fos.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } catch (FileNotFoundException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } try { client_socket2.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } </code></pre> <p>and the client side (the sending side is like this):</p> <pre><code>public void run(){ try { Method m = send_dev.getClass().getMethod("createRfcommSocket", new Class[] {int.class}); Csocket = (BluetoothSocket) m.invoke(send_dev, 1); Csocket.connect(); manageSendConnection(Csocket); }catch(Exception e){ e.printStackTrace(); } } //function to handle after connection is established. private void manageSendConnection(BluetoothSocket csocket) { // TODO Auto-generated method stub File f = new File("/sdcard/myfolder/card3.Xcard"); byte[] buffer = new byte[(int)f.length()]; try { FileInputStream fis = new FileInputStream(f); BufferedInputStream bis = new BufferedInputStream(fis); try { bis.read(buffer, 0, (int)f.length()); OutputStream os = csocket.getOutputStream(); os.write(buffer); os.close(); fis.close(); bis.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } catch (FileNotFoundException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } try { csocket.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } </code></pre> <p>I am getting the pairing request but the data is not being sent. can anyone please help me to find the problem and give a hint on solution??</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
