Should we do something similar on Android to handle directions mode?

https://developers.google.com/maps/documentation/urls/android-intents#launch_turn_by_turn_navigation

It looks like we could technically call the intent uri google.navigation: and add a mode=w to it. However this of course is more opinionated on which app it should use to launch navigation (though I wonder if other apps register themselves to handle that prefix and maybe this is ok).

@Redth implemented!
