If you use @ionic-native/google-maps, please tell the package.json (only @ionic-native/core and @ionic-native/google-maps are fine mostly) I am using the ionic map provider example’s package.json Current behavior:

I am trying to run the ionic map provider example, but it ran with a white blank map. All the tabs are shown and navigating correctly. I have checked that my API keys are correct, as i am using those same keys in other apps and they work. My android device is on android version 5.0.2, and i am using it to test other google map apps too ie it should be working.
Expected behavior:

Expected a properly rendered map from the ionic map provider example.

But anyway, it’s not so important. You just create a blank project, and replace the src folder to https://github.com/mapsplugin/ionic-map-provider-example/tree/master/src
