HI everyone,

Using asynctask in android, for tcp/ip connection how can i ensure client is connected or not. I have to disconnect connection using asynctask manually. Please help how to do????????????????


This is the code i used:

  public class MyClientTask extends AsyncTask<void,> {

String dstAddress;
int dstPort;
String response = "";

MyClientTask(String addr, int port)
{
 dstAddress = addr;
 dstPort = port;
}

@Override
protected Void doInBackground(Void... arg0) {
  try {
  GlobalClass.socket = new Socket(dstAddress, dstPort);

  ByteArrayOutputStream byteArrayOutputStream =
                new ByteArrayOutputStream(1024);
  byte[] buffer = new byte[1024];

  int bytesRead;
  InputStream inputStream = GlobalClass.socket.getInputStream();

while ((bytesRead = inputStream.read(buffer)) != -1){
               byteArrayOutputStream.write(buffer, 0, bytesRead);
               response += byteArrayOutputStream.toString("UTF-8");
           }

 } catch (UnknownHostException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
  response = "UnknownHostException: " + e.toString();
 } catch (IOException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
  response = "IOException: " + e.toString();
 }finally{
  if(GlobalClass.socket != null){
   try {
    GlobalClass.socket.close();
   } catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
  }
 }
 return null;
}

and in connect button i call:

MyClientTask myClientTask = new         MyClientTask(ip.getText().toString(),Integer.parseInt(port.getText().toString()));
                           myClientTask.execute();

and when required i need to disconnect the socket.....
