I am currently stuck with this problem: Google Maps seems not to be loading at all. Please see the image below: 
This is really driving me crazy. I already have done the following:
- Added my package name + SHA1 (debug keystore) + SHA1 (release keystore) to Google Developer's console
- Maps SDK for Android is enabled. The API key has Android app restriction
- Added google-services.json to my app from Firebase console
- Added necessary permissions:
- Added API Key to the Manifest file - from Google Developer Console
- Added meta data for gms version
This is the code of my fragment:

}
@Override

SupportMapFragment mapFragment = (SupportMapFragment) this.getChildFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
return view;
}
@Override
public void onMapReady(GoogleMap googleMap) {
LatLng augsburg = new LatLng(48.348527, 10.915952);
if (ActivityCompat.checkSelfPermission(getActivity(), android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getActivity(), android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

return;
}
googleMap.setMyLocationEnabled(true);
googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(augsburg, 13));
googleMap.addMarker(new MarkerOptions()
.title("Augsburg Zoo")
.snippet("Der coolste Zoo der Welt")
.position(augsburg));
}
}
And this is the code for my layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/constraintLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<TextView
android:id="@+id/textView15"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="Coming soon!"
android:textColor="@color/colorPrimary"
android:textSize="30sp"
android:visibility="invisible" />
</RelativeLayout>
Can anyone tell what still I'm missing?
