I would like to make an app that pushes Google Now cards to the Pebble SmartWatch. Is there a way to access Google Now cards programmatically? I'm guessing from my googling that it's not officially supported, but have people found out any undocumented APIs that access this information?
AFAIK there are no official or unofficial APIs as of now to retrieve the Google Now cards, and there are unlikely to be as it is a proprietary app by Google that gives them a competitive advantage, and not part of the AOSP Android.
