Làm cách nào để kết nối Android Studio với cơ sở dữ liệu SQL Server?

Trước khi kết nối, bạn phải thêm 2 dòng mã:

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

Hoàn thành mã như:(có thể là)

package com.ipvsoft.sendsms.utility;

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

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


public class SQLConnection {
    private static final String LOG = "DEBUG";
    private static String ip = "192.168.3.85";
    private static String port = "1433";
    private static String classs = "net.sourceforge.jtds.jdbc.Driver";
    private static String db = "THTData";
    private static String un = "sa";
    private static String password = "admin";
    public static Connection connect() {
        Connection conn = null;
        String ConnURL = null;
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
        try {
            Class.forName(classs);
            ConnURL = "jdbc:jtds:sqlserver://" + ip +":"+port+";"
                    + "databaseName=" + db + ";user=" + un + ";password="
                    + password + ";";
            conn = DriverManager.getConnection(ConnURL);
        } catch (SQLException e) {
            Log.d(LOG, e.getMessage());
        } catch (ClassNotFoundException e) {
            Log.d(LOG, e.getMessage());
        }
        return conn;
    }
}
