Tried @aaronksaunders repository an all working. Many thanks to @aaronksaunders and @iignatov for your great help!
Other mistakes I had and solved with the repo were:
- I hadn’t installed from SDK the Google Repository and services packages.
- I was using JS key for devices.
- I didn’t execute
cordova prepare. - The plugin wasn’t installed from phonegap googlemaps github but like in ionic-native docs.
Thanks!
