/* Google Analytics Data API sample application demonstrating the usage of
dimension and metric filters in a report.

See
https://developers.google.com/analytics/devguides/reporting/data/v1/rest/v1beta/properties/runReport#body.request_body.FIELDS.dimension_filter
for more information.

Before you start the application, please review the comments starting with
"TODO(developer)" and update the code to use correct values.

To run this sample using Maven:
  cd java-analytics-data/samples/snippets
  mvn compile
  mvn exec:java -Dexec.mainClass="com.example.analytics.RunReportWithDimensionInListFilterSample"
