I am looking to render a map on a Glass timeline and I already have the location (lat, long) from another service. I tried rendering these coordinates as per the article here: https://developers.google.com/glass/location#rendering_maps_on_timeline_cards but my map does not render.
I tried researching around this, but could not figure out the problem.
Tried this on Glass Playground and used my coordinates, the maps just do not render.
For glass://maps to work, do I need to enable any other API service on my google developer account ? Please advise.
The Mirror API Playground does not support rendering maps in cards. You need to test this using Glass.
The playground is a tool primarily intended for working on card layouts. It supports many features of the API, but not everything.
