There's an update for Google Calendar available now in the Google Play Store, and it's going to make adding locations to events a tad easier. The update is relatively minor, but it brings a recently-added feature from the web version of Google Calendar to the Android app: location autocomplete from Google Maps. All you have to do is start typing in the location field on an appointment and Google Maps' extensive address and point of interest database will be queried to provide you as-you-type autocomplete predictions. This can be especially handy when you want to ensure you have a correct address for someplace you'll be using your phone's navigation tools to reach.
The Google Calendar app update is propagating now through the Google Play Store for your updating pleasure.
