Code Walkthrough

1. authorize() method authorizes the installed application to access the user's protected data. The resource class (ReadGoogleAnalyticsGoalConversions) and OAuth 2.0 scopes are also defined in this method body along with credentials.
2. NetHttpTransport instance is created to thread-safe HTTP low-level transport.
3. GoogleAnalyticsReportReader uses an API to get analytics of social interactions from Google. The constructor of the instance accepts GoogleCredentials and VIEW_ID. Additional parameters such as date range, dimensions, metrics, and application name are specified using corresponding methods.
4. StreamWriter.newSystemOutWriter() method is used to create DataWriter instance.
5. Job.run() method is used to transfer the data from reader to writer to print out the records on the console. See how to compile and run data pipeline jobs.
