Maps Android Studio is not displayed

Android Studio preparations

Following the steps in the Android Maps guide I have been able to extract the prerequisites to use the Google Maps service.

Install the Google play Services from the SDK Manager Create apikey from Google Places API for Android in console: console developer

Add dependencies in File app.graddle

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.2.1'
    compile 'com.android.support:design:23.2.1'
    compile 'com.google.android.gms:play-services:8.4.0'
}

Create values/google_maps_api.xml

<resources>
    <string name="google_maps_key" templateMergeStrategy="preserve" translatable="false">
        <!-- código de la APIKEY
        https://developers.google.com/maps/documentation/android/start#get-key
        -->
    </string>
</resources>

Apply permission ACCESS_FINE_LOCATION in file Manifest.xml to being able to use google maps

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

And define new activity

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

<activity
    android:name=".MapsActivity"
    android:label="@string/title_activity_maps"></activity>

Create the layout layout/activity_maps.xml

<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.testsettings.app.testgooglemaps.MapsActivity" />

The activity where you want to use the Google maps element has to inherit from FragmentActiity and load the interface OnMapReadyCallback

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

    private GoogleMap mMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    }


    /**
     * Manipulates the map once available.
     * This callback is triggered when the map is ready to be used.
     * This is where we can add markers or lines, add listeners or move the camera. In this case,
     * we just add a marker near Sydney, Australia.
     * If Google Play services is not installed on the device, the user will be prompted to install
     * it inside the SupportMapFragment. This method will only be triggered once the user has
     * installed Google Play services and returned to the app.
     */
    @Override
    public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;

        // Add a marker in Sydney and move the camera
        LatLng myLocation = new LatLng(13.0810, 80.2740);
        mMap.addMarker(new MarkerOptions().position(myLocation).title("Marker in Sydney"));
        mMap.moveCamera(CameraUpdateFactory.newLatLng(myLocation));
        mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(
                new LatLng(myLocation.latitude, myLocation.longitude), 11.0f), 1500, null);

    }
}

I have the same problem, but to me it does not load me when the device has only GPS enabled, when the " Location Mode "is in" high precision mode " with networks and Wifi, the map loads perfectly.. I know that wasn't your problem, but I'll leave it in case someone's having the same thing as me.
