Error While connecting to SQL server in android application using eclipse

Question

I am finding exception on "conn = DriverManager.getConnection(connString, username, password); Line.

public void query2() {
    Log.i("Android", " MySQL Connect Example.");
    Connection conn = null;
    try {
        String driver = "net.sourceforge.jtds.jdbc.Driver";
        System.out.println("*************inside class 1**************");
        Class.forName(driver).newInstance();

       // test = com.microsoft.sqlserver.jdbc.SQLServerDriver.class;
        System.out.println("*************inside class 2**************");
        String connString = "jdbc:jtds:sqlserver://localhost:1433;" +
                "DatabaseName=test;user=sa;password=sa1;";
        System.out.println("*************inside class 3**************");
        String username = "sa";
        String password = "sa1";
        conn = DriverManager.getConnection(connString, username, password);
        Log.w("Connection", "open");
        Statement stmt = conn.createStatement();
        ResultSet reset = stmt.executeQuery("select * from titles");

        // Print the data to the console
        while (reset.next()) {
            Log.w("Data:", reset.getString(3));
            // Log.w("Data",reset.getString(2));

        }
        conn.close();

    } catch (Exception e) {
        Log.w("Error connection", "" + e.getMessage());
    }
}

My Log cat display:

Answer 1

Your connection string looks malformed. Also MySQL default port is 3306. Unless you changed the port number you should use 3306. Pull the username and passwrod out of the Connstring. If you are using

getConnection (ConnStr, User, Password) 

you don't need to set it in the conn string as you're passing it in the call.

Try this conn string which is bare bones but should connect. Make sure to use getConnection and pass in username/password

jdbc:jtds:sqlserver://localhost:3306/test

If this does not work you will need to output more info and errors to Logcat. Look here to understand how to use Logcat. You don't have any error messages in Logcat in your Post, only Info and Warning
