How to use Google Maps API to show Google Maps in Xamarin.Forms SfMaps control

Platform: Xamarin.Forms |
Control: SfMaps |
Published Date: July 6, 2018 |
Last Revised Date: May 6, 2021


This article describes how to use Google Maps API to show Google Maps using ImageryLayer of the Xamarin Maps(SfMaps) control.


You can show the Google Maps using the RequestTileUri event of ImageryLayer.

Step 1: Subscribe the RequestTileUri event of ImageryLayer as demonstrated in the following code example.


         <maps:ImageryLayer RequestTileUri="ImageryLayer_RequestTileUri">
                <maps:MapMarkerSetting MarkerIcon="Image" ImageSource="pin.png" IconSize="15"/>
                    <maps:MapMarker Latitude="38.8833" Longitude= "-77.0167"/>
                    <maps:MapMarker Latitude="-15.7833" Longitude= "-47.8667"/>
                    <maps:MapMarker  Latitude="21.0000" Longitude= "78.0000"/>
                    <maps:MapMarker Latitude="35.0000" Longitude= "103.0000" />
                    <maps:MapMarker Latitude="-4.0383" Longitude= "21.7586" />


Step 2: In the RequestTileUri event, assign the Google Maps API Uri link (or any tile maps provider) to corresponding x, y, and zoom level of the Uri property of TileUriArgs as demonstrated in the following code example.


/// <summary>
/// This event is used to pass the uri of desired maps tile provider.
/// </summary>
/// <param name="sender">The imagery layer</param>
/// <param name="e">The Tile uri arguments</param>
private void ImageryLayer_RequestTileUri(object sender, Syncfusion.SfMaps.XForms.TileUriArgs e)
            var link = "http://mt1.google.com/vt/lyrs=y&x=" + e.X.ToString() + "&y=" + e.Y.ToString() + "&z=" + e.ZoomLevel.ToString();
            e.Uri = link;

Everything added to the imagelayer on line 7 of MainPage will be removed by line 16 in CustomMapRenderer.

This solution completely removes the ability to add any custom markers on the map.

Before clearing the Layers collection from maps, you have to assign the old imagery layer properties to new extended  imager layer(ImageryLayerExt). For example, you have to assign old layer markers collection to the ImageryLayerExt’s markers collection to display the marker  as in below code. 

Please use the following code in the CustomMapRenderer.


void AddLayer()


ImageryLayerExt layer = new ImageryLayerExt();

NativeMap.SfMaps nativeMap = (Control as NativeMap.SfMaps);

var nativeLayer = nativeMap.Layers[0] as NativeMap.ImageryLayer;

if(nativeLayer != null)

  layer.Markers = nativeLayer.Markers;


nativeMap.Layers.Add(layer as NativeMap.ImageryLayer);

From version, we have provided direct API as RequestTileUri to achieve this supportwithout using custom renderer for each platform. We have modified the sample and code based on new API.
