Question

We are currently having the same problem as here: How to connect Android Studio with SQL Server database, but it hasn\'t been answered.

We also succeeded the connect

Answer 1

Before you make connection, you must add 2 lines of code:

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

Complete code as: (may be)

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;
    }
}

Answer 2

The error that you are getting is because you are missing the line Class.forName("net.sourceforge.jtds.jdbc.Driver");

Add it before establishing the database connection, so it will look something like this in your code:

String url = "jdbc:jtdc:sqlserver://vps342074.ovh.net/IZY309";
try {
    //TextView textViewToChange = (TextView) findViewById(R.id.textViewCol5);
    //textViewToChange.setText("Hello");
    Class.forName("net.sourceforge.jtds.jdbc.Driver");

    Connection con = DriverManager.getConnection(url, user, pass);

    Statement statement = con.createStatement();
    ResultSet resultat = statement.executeQuery("SELECT CATEGORIE FROM dbo.PPROFIL WHERE CATEGORIE = 'ac' ");
    while (resultat.next()) {

        String result = resultat.getString(1);
        TextView textViewToChange = (TextView) findViewById(R.id.textViewCol5);
        textViewToChange.setText(result);
        Log.d("My Custom Tag", result);
    }
    resultat.close();
    statement.close();

} catch (SQLException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
