I am new to Android and am trying to display a Google Map on an Android Phone. I created the API Key that should work for any Android App ( I did not give any specific SHA for my app). I am guessing that should not matter. Using the Google Android Tutorials, I am doing all the steps, I get the google watermark on the left bottom, but no map. I will post all the code being used. I have tried to use the Google Maps Activity shipped in Android Studio 1.2.1.1. I don't get any errors, but don't get the map either.

I am using a MapFragment as it seems to be easier than the MapView.

I also viewed the developers console for this API - I dont have any traffic - could it be that the API key is not being used and so my app is not getting the report? I suspect that - how can I test that?

I am trying to follow the steps here - https://developers.google.com/maps/documentation/android/map

Another related query is, I am assuming I can create mutiple layouts. I started with a Blank Activity that acts as my Splash screen, then I am trying to go to a Map Activity - I am not able to create a Map Activity inside Android Studio. I can create it as the first activity through the wizard, but not as a second activity. Am I missing something?

Any help is appreciated

I have also used File->Project Structure ->Dependencies - App-> and found that Google Play Services is included.

MapsActivity.java

    package com.nbapl.avapps.mapscreen;

import com.google.android.gms.maps.*;
import com.google.android.gms.maps.model.*;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {


     @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map);

        MapFragment mapFragment = (MapFragment) getFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    }



    @Override
    public void onMapReady(GoogleMap map) {
            map.addMarker(new MarkerOptions()
               .position(new LatLng(0, 0))
               .title("This is the center"));
        }

    }

Here is the Layout xml

    <?xml version="1.0" encoding="utf-8"?>

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/frame"
    android:background="#ffe2ff0e"
    android:clickable="false"
    android:foreground="#fffff9c5">

android:id="@+id/map"
android:layout_width="match_parent"

</FrameLayout>
