first activity :

protected void onPause() {
        Toast.makeText(this, "service unbinded", Toast.LENGTH_LONG).show();
        unbindService(myconn);

        super.onPause();
    }

public void OnShowDevices(View v){
        //unbindService(myconn);
        Intent in = new Intent(this , ConnectedDevice.class);
        startActivity(in);
    }

protected void onResume() {
        // TODO Auto-generated method stub
        super.onResume();
        Intent intq = new Intent(this ,Server.class);
        startService(intq);
        bindService(intq, myconn, Context.BIND_AUTO_CREATE);

            //startService(intq);
            bindService(intq, myconn, Context.BIND_AUTO_CREATE);
             //GridView gridview = (GridView) findViewById(R.id.lstDevices);
               // gridview.setAdapter(new DeviceAdaptor(this, ser.Clients()));

        }
        catch(Exception ex)
        {
            Toast.makeText(this, ex.getMessage(), Toast.LENGTH_SHORT).show();
        }
