How to connect to sql anywhere 9 sybase from android?

I have a database in sql anywhere 9.0 and work through sybase, I have a desktop application in POWER BUILDER that enters products, which I want to show them in an application made in android studio, I just have to show a list of those products in my android project, for which I tried to connect using jdbc. In Power builder, I use the odbc to connect, but I know that android uses jdbc, I would like to connect to that database to get the data, I have tried the following: Class.forName("net.sourceforge.jtds.jdbc.Driver"); ConectionURL="jdbc:jtds:odbc:driver={Adaptive Server Anywhere 9.0};ENG=ARCHIVO;UID=" + us + ";PWD="+ pass + ";DBN="+bd + ";LINK=TCPIP(HOST="+ip+":2638)"; con = DriverManager.getConnection(ConectionURL); the jtds is a library downloaded from the internet that allows connections with sql server, the download and the probe in my application but I do not know if it is the correct way to implement it, can someone help me by telling me how to put the url and the class? Below I put the complete code of my connection.

    package com.example.systemsecpc3.aplicacionsystemsproductos.connections;

import android.annotation.SuppressLint;
import android.os.StrictMode;
import android.util.Log;

import java.sql.Connection;
import java.sql.Driver;
import java.sql.DriverManager;
import java.sql.SQLException;

public class Conexion {


    //declaramos las variables de conexion
    Connection con = null;
    public String ip, bd, us, pass;

    @SuppressLint("NewApi")
    public Conexion(String usuariobd, String clavebd, String BaseDatos, String ServerIp){
        us=usuariobd;
        bd=BaseDatos;
        pass=clavebd;
        ip=ServerIp;

        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
        String ConectionURL =null;

        try {
            Class.forName("net.sourceforge.jtds.jdbc.Driver");
            ConectionURL="jdbc:jtds:odbc:driver={Adaptive Server Anywhere 9.0};ENG=ARCHIVO;UID=" + us + ";PWD="+ pass + ";DBN="+bd + ";LINK=TCPIP(HOST="+ip+":2638)";
            con = DriverManager.getConnection(ConectionURL);

        }catch (SQLException se)
        {
            Log.e("Error SQL 1 : ", se.getMessage());
        }
        catch (ClassNotFoundException  e)
        {
            Log.e("Error Class 2 : ", e.getMessage());
        }
        catch (Exception e)
        {
            Log.e("Error Exception 3 : ", e.getMessage());
        }

    }


    public Connection getConnection(){
        return con;
    }
    public void desconectar(){
        con = null;
    }
}


y este es el codigo de mi mainactivity

        setContentView(R.layout.activity_main);

        //obtenemos en la variable los elementos del layout
        probar = (Button) findViewById(R.id.button);
        texto = (TextView) findViewById(R.id.textView);

        probar.setOnClickListener(new View.OnClickListener() {

                Conexion cc=new Conexion("dba","sql", "SYSTEMS","192.168.1.126");
                Connection cn= cc.getConnection();
                Statement st=null;

                    rs=st.executeQuery("select max(*) from bo_producto");
                    if(rs.next())
                    {
                        texto.setText(rs.getString("ENCTONTRÓ DATOS"));
                    }
                    else

                    }
                } catch (SQLException ex) {
                    Log.e("Error here 1 : ", ex.getMessage());
                }
            }
        });

    }
