The very first thing to do is to tell the library the name of your app. This name needs to be unique in order to identify your app. You can use any name that fits, but don't use spaces or special characters in it. Then call

Common.setAppName(myappname);

This should be one of the first things your application does as many features of the libraray actually depend on the app name and will throw an exception if no name was defined.

Next, you might want to check for updates, save preferences, log events or do many other things that the library can do for you. Just have a look at the JavaDoc.
