When the user first enters the GoogleMapsActivity it does not automatically take them to their location, the user has to click the little location icon button at the top right and it will take them to their location.
I have tried using newLatLngZoom(latLng, zoom) but that didn't work. And I went through all the suggested questions before posting this question, and none worked. Some were in iOS too. I am using Android.

I expect Google Maps to automatically go to the users location when they first go into the Google Maps Activity, but instead the user has to click the location button at the top right corner to send them there. Thanks for your help and advice in advanced!
