my android code is

        JSONRPCClient clientrpc = JSONRPCClient.create("http://192.168.1.102/server.php",JSONRPCParams.Versions.VERSION_2);
      clientrpc.setConnectionTimeout(2000);

      clientrpc.setSoTimeout(2000);
        try 
        {
          JSONArray stringdata = clientrpc.callJSONArray("login","demo","123456");

          try {
            Toast.makeText(getApplicationContext(),
                        stringdata.getString(1), Toast.LENGTH_SHORT)
                        .show();
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            //  e.printStackTrace();
            Toast.makeText(getApplicationContext(),
                    "ERROR ON CHECKLOGIN", Toast.LENGTH_SHORT)
                    .show();
        }

        }
        catch (JSONRPCException e)
        {
          e.printStackTrace();
            Toast.makeText(getApplicationContext(),
                    "Error ON server connection", Toast.LENGTH_SHORT)
