Google Maps is showing a blank map

I am currently stuck with this problem: Google Maps seems not to be loading at all. Please see the image below: enter image description here

This is really driving me crazy. I already have done the following:

  1. Added my package name + SHA1 (debug keystore) + SHA1 (release keystore) to Google Developer's console
  2. Maps SDK for Android is enabled. The API key has Android app restriction
  3. Added google-services.json to my app from Firebase console
  4. Added necessary permissions:
  5. Added API Key to the Manifest file - from Google Developer Console
  6. Added meta data for gms version

This is the code of my fragment:

import android.content.Context;
import android.content.pm.FeatureInfo;
import android.content.pm.PackageManager;
import android.support.v4.app.ActivityCompat;

            }
        }
        else if (checker.isUserResolvableError(status)) {

        }
        else {

        }

        return(false);

                // gl es version feature.
                if (featureInfo.name == null) {
                    if (featureInfo.reqGlEsVersion != FeatureInfo.GL_ES_VERSION_UNDEFINED) {
                        return getMajorVersion(featureInfo.reqGlEsVersion);
                    }
                    else {
                        return 1; // Lack of property means OpenGL ES
                        // version 1
                    }
                }

        }

    }
    private static int getMajorVersion(int glEsVersion) {

    }
    public static MapsActivity newInstance() {
        MapsActivity fragment = new MapsActivity();
        return fragment;
    }

    public MapsActivity() {
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        readyToGo();

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.activity_maps, null, false);

        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) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            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?
