Google map layout called from button press crash

Question

I'm trying to implement Google Maps API in an Android application. This works just fine when the google map is in an app alone But when I try to open the layout containing the map via a button tap from another layout, it crashes at the line: setContentView(R.layout.activity_maps); in the mapsactivity.java.

here is the function used to call the map layout:

public void runSSH(View v) {

    Intent intent = new Intent(this, MapsActivity.class);
    startActivity(intent);
}

The mapsactivity.java was auto generated by AndroidStudio, but I will still put it here:

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

private GoogleMap mMap;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);
}


@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;

    // Add a marker in Sydney and move the camera
    LatLng sydney = new LatLng(-34, 151);
    mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
    mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}
}

And here is the Activitymaps.xml (auto-generated as well):

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.hosenbocus.azhar.droner.MapsActivity" />

I did add the API key in the manifest and in the google_maps_api.xml

<meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="MYKEY-AIzaSyCf0-a3jUzVrL4PJwCo1q6W60YTxu-U7F0" />
<meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="@string/google_maps_key" />




<string name="google_maps_key" templateMergeStrategy="preserve" translatable="false">
    AIzaSyCf0-a3jUzVrL4PJwCo1q6W60YTxu-U7F0
</string>

Here is the trace log:

Please help me, I'm stuck on this for 2 days already now. I'm a beginner to android development, there might be something obvious that I missed.

Thanks in advance

Problem is :

The API key can only be specified once. It is recommended that you use the meta-data tag with the name: com.google.android.geo.API_KEY in the <application> element of AndroidManifest.xml

Instant of

<meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="MYKEY-AIzaSyCf0-a3jUzVrL4PJwCo1q6W60YTxu-U7F0" />
<meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="@string/google_maps_key" />

use only

<meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="@string/google_maps_key" />
