Change calendar location viewer
I'm prompted to select what I want to use to open the link, so it looks like you've set a default action for that Intent.

You'll need to go to Settings &gt; Apps &gt; (downloaded or all) &gt; Earth &gt; Clear defaults. Next time you click a location in the calendar it should prompt you for what you want to use to open it.

Unfortunately, this resets all the defaults for Google Earth.
