Display map coordinates on the timeline

Question

I am looking to display a map on a glass timeline, and I already have a place (lat, long) from another service. I tried to fulfill these coordinates according to the article here: https://developers.google.com/glass/location#rendering_maps_on_timeline_cards , but my map does not display.

I tried to research this, but could not understand the problem.

I tried it on the Glass Playground and used my coordinates, the maps simply did not appear.

For glass: // maps to work, do I need to include any other API service in my Google developer account? Please inform.

Answer 1

Mirror API Playground does not support displaying cards in cards. You need to check this using Glass.

A playground is a tool designed primarily for working with map layouts. It supports many API functions, but not all.
