Google calendar API OAUTH

I'm trying to make a Java app (stand alone not web based) that connects to Google calendar but im having issues getting past the OAuth stage. I have looked over every part of the Google API i can see.

The newest version i can find is at https://developers.google.com/google-apps/calendar/instantiate

I have downloaded the 2 sets of JAR files they say to (google-api-services-calendar-v3-rev3-1.5.0-beta and gdata-samples.java-1.46.0) and imported the required libraries and dependencies. This gives me deprication errors for about half the classes and some methods (mainly new Calendar(httpTransport, accessProtectedResource, jsonFactory);) dont work at all.

Has anyone got a basic example of getting an OAuth token and accessing the Google Calendar API? Am i looking at this the wrong way or am i using an out of date copy of the api?

Is gdata still in use or has it been replaced? Thanks Adrian

GData is still in use but is considered deprecated. Somewhere I read that it will be considered obsolete sometime in 2014. Take a look at this post and see if it answers your question. It's written for C# so maybe it will be too different: stackoverflow.com/questions/8899000/… - HK1

You need to first get oauth working then use oauth to call some google api for example calendar.

Start from google oauth 1 for installed app or google oauth 2 for installed app or search for "google oauth installed app". Scrib is a good oauth lib for Java.

I have no idea why the code is listed wrong in the documentation. The line below worked for me.

Calendar(httpTransport, jsonFactory, accessProtectedResource);
