private static void printAbout(Drive service) {
try {
  About about = service.about().get().execute();

  System.out.println("Current user name: " + about.getName());
  System.out.println("Root folder ID: " + about.getRootFolderId());
  System.out.println("Total quota (bytes): " + about.getQuotaBytesTotal());
  System.out.println("Used quota (bytes): " + about.getQuotaBytesUsed());

  System.out.println("An error occurred: " + e);
}
  }

It won't allow you to do this on the main thread because it would lock your app until it's finished. And if this procedure takes more than 5 seconds, the Android OS would close your app.

You need to use a background thread like AsyncTasks.
