google-analytics-api Metadata api Java example

Example

uses the Java Client library

/**
 * 1. Execute a Metadata Request
 * An application can request columns data by calling the list method on the Analytics service object.
 * The method requires an reportType parameter that specifies the column data to retrieve.
 * For example, the following code requests columns for the ga report type.
 */

try {
  Columns results = getMetadata(analytics);
  // Success

} catch (GoogleJsonResponseException e) {
  // Catch API specific errors.
  handleApiError(e);
} catch (IOException e) {
  // Catch general parsing network errors.
  e.printStackTrace();
}

 * 2. Print out the Columns data
 * The components of the result can be printed out as follows:
