Error trying to create a connection to the database (MySQL)

I tried to make a connection to the MySQL database using AsyncTask , but it is giving error in the class responsible for the connection, MysqlConnect :

  

The Log () constructor is not visible

I'm following this tutorial and my problem is in the following excerpt from MysqlConnect :

public MysqlConnect(Context context) {
    this.context = context;
    log = new Log();
}

My MysqlConnect.java :

package br.com.alerts;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;
import java.sql.Statement;
import android.app.ProgressDialog;
import android.content.Context;
import android.os.AsyncTask;
import android.util.Log;

public class MysqlConnect extends AsyncTask<Void, Void, Boolean> {

    private static final String url = "jdbc:mysql://mysql.hostinger.com.br/u259053814_table";
    private static final String user = "root";
    private static final String pass = "root";
    private Connection con;
    private Log log;
    private Context context;
    private ProgressDialog dialog;

    public MysqlConnect(Context context) {
        this.context = context;
        log = new Log();
    }
    public Boolean isConected() {
        try
        {
            if (con == null)
            {
                return false;
            } else {
                return (!this.con.isClosed());
            } 
        } catch (SQLException e) {
            return false;
        }
    }
    public String getLog() {
        return log.toString();
    }
    public boolean connect() {
        try
        {
            Class.forName("com.mysql.jdbc.Driver");
            con = DriverManager.getConnection(url, user, pass);
            log.add("Conectado com sucesso!");
        } catch(Exception e) {
            e.printStackTrace();
        }
        return isConected();
    }
    public void disconnect() {
        try {
            con.close();
            con.isClosed();
            log.add("Desconectado!");
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        dialog = new ProgressDialog(this.context);
        dialog.setMessage("Aguarde... conectando ao banco de dados...");
        dialog.show();
    }
    @Override
    protected Boolean doInBackground(Void... params) {
        connect();
        return isConected();
    }
    @Override
    protected void onPostExecute(Boolean result) {
        super.onPostExecute(result);
        dialog.dismiss();
    }
}
