I can't seem to find any information on the Application Name used by various Google API services. The best I can figure is that it might simply be a name that will display on the consent screen? Below is an example of the application name I'm talking about.
calendarService = new Calendar.Builder( HTTP_TRANSPORT , JSON_FACTORY , credential )
.setApplicationName( applicationName )
.build();
Also, if I create multiple calendarServices, would/should I give each a unique application name?
