Question

I found some answers but nothing was useful.

I added mysql-connector-java-5.1.7-bin.jar to referenced libraries and the following method to my main class activity.

private void getServerData(String id, String type) throws InstantiationException, IllegalAccessException, ClassNotFoundException, SQLException
{
    Log.i("Database Connection", " requesting data from server");

    Class.forName("com.mysql.jdbc.Driver").newInstance();               
    Connection con = DriverManager.getConnection("jdbc:mysql://10.0.2.2:3306/db_easy_maintenance", "root", "maintenance");
    Statement stm = con.createStatement();
    ResultSet rs = stm.executeQuery("SELECT Name FROM industrial_object");
    String entry;
    while(rs.next())
    {
        entry=rs.getString("Name");
        Log.i("Database Connection", "getting " + entry);
    }

    con.close();

}

I start my app and get an java.lang.ClassNotFoundException: com.mysql.jdbc.Driver at java.lang.Class.classForName.

If I don’t use try …catch… then i get this Exception before compiling.

What’s wrong?

see: http://developer.android.com/search.html#q=dx&t=0
and Android JDBC not working: ClassNotFoundException on driver – my answer on the bottom gives ridiculously specific instructions, although I am curious how switching to 1.6 was useful.
