java.lang.ClassNotFoundException: org.postgresql.Driver, Android

I am running Eclipse on Windows.

Following this tutorial I downloaded JDBC4, added it to my build path using Project>Properties>add External JAR, browsed for the file, it worked (.classpath file shows the correct lib path).

The package appears in my Referenced Libraries folder, so I continue the tutorial.

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


    public void open ()
    try {
    } catch (ClassNotFoundException e) {

    try {
        conn = DriverManager.getConnection(url, username, password);
    } catch (SQLException e) {

I think it would be as simple as that but I get hit with this big long stack trace starting with

    java.lang.ClassNotFoundException: org.postgresql.Driver

(I can provide more if needed)

I tried include org.postgresql.*; but that didn’t help either. I have also tried the JDBC3 but no luck there either.

I looked at Driver JDBC PostgreSQL with Android which provided a vague answer saying I would be better off just using HTTP+JSON. Which I have never used.

I’m brand new to Android, postgresql, web development, so a simple answer would be appreciated.
