How to display Google Map in an Android app using Xamarin

Question

I am designing an android app with Xamarin which will have an activity with google maps inside it, but i am struggling to display the map. It shows an empty box with no map display on it. Following is the code which i used for this practice.

My Activity

namespace teslin
{
    [Activity(Label = "Map")]
    public class MpActivity : Android.GoogleMaps.MapActivity
    {
        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);
           SetContentView(Resource.Layout.MapView);
           var map = FindViewById<MapView>(Resource.Id.mapv);
           map.Clickable = true;
           map.Controller.SetZoom(16);
          map.Controller.SetCenter(new GeoPoint((int)40.8270449E6, (int)-73.9279148E6));
}}

xml lay out

        <LinearLayout
            android:orientation="horizontal"
            android:minWidth="25px"
            android:minHeight="25px"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/linearLayout3"
            android:layout_weight="9" />
        <com.google.android.maps.MapView
            android:id="@+id/mapv"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:enabled="true"
            android:apiKey="AIzaSyD-UMij5IO6ezjuFCNnF7tRoG3niaPbNEU" />
    </LinearLayout>

It looks like you're using the obsolete/outdated Maps API v1. Google removed support for this last year.

Instead you want to use Android Maps API v2 (a part of Google Play Services). Xamarin has some documentation on Maps in Android. It can be a bit tricky to get Maps working in Android, so carefully read these docs. Specifically, you'll want to read the section on the Maps API.

There is an example on Github that shows how to use the Google Play Services Component to add Maps to your application.
