NativeScript plugin for the Google Maps SDK

This is a cross-platform (iOS & Android) Nativescript plugin for the Google Maps API.

Prerequisites

iOS - Cocoapods must be installed.

Android - The latest version of the Google Play Services SDK must be installed.

Google Maps API Key - Visit the Google Developers Console, create a project, and enable the Google Maps Android API and Google Maps SDK for iOS APIs. Then, under credentials, create an API key.

Installation

Install the plugin using the NativeScript CLI tooling:

Nativescript 7+

tns plugin add nativescript-google-maps-sdk

Nativescript < 7

tns plugin add nativescript-google-maps-sdk@2.9.1

Setup

See demo code included here

See a live demo here

Configure API Key for Android

Nativescript < 4

Start by copying the necessary template resource files in to the Android app resources folder:

cp -r node_modules/nativescript-google-maps-sdk/platforms/android/res/values app/App_Resources/Android/

Next, modify your app/App_Resources/Android/values/nativescript_google_maps_api.xml file by uncommenting the nativescript_google_maps_api_key string, and replace PUT_API_KEY_HERE with the API key you created earlier.

Finally, modify your app/App_Resources/Android/AndroidManifest.xml file by inserting the following in between the <application> tags:

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

Nativescript 4+

Start by copying the necessary template resource files in to the Android app resources folder:

cp -r node_modules/nativescript-google-maps-sdk/platforms/android/res/values app/App_Resources/Android/src/main/res

Next, modify your app/App_Resources/Android/src/main/res/values/nativescript_google_maps_api.xml file by uncommenting the nativescript_google_maps_api_key string, and replace PUT_API_KEY_HERE with the API key you created earlier.

Finally, modify your app/App_Resources/Android/src/main/AndroidManifest.xml file by inserting the following in between your <application> tags:

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

The plugin will default to the latest available version of the Google Play Services SDK for Android. If you need to change the version, you can add a project.ext property, googlePlayServicesVersion, like so:

//   /app/App_Resources/Android/app.gradle

project.ext {
    googlePlayServicesVersion = "+"
}

Configure API Key for iOS

In your app.js, use the following code to add your API key (replace PUT_API_KEY_HERE with the API key you created earlier):

if (application.ios) {
    GMSServices.provideAPIKey("PUT_API_KEY_HERE");
}

If you are using Angular, modify your app.module.ts as follows:

import * as platform from "platform";
declare var GMSServices: any;

....

if (platform.isIOS) { 
    GMSServices.provideAPIKey("PUT_API_KEY_HERE");
}

Adding the MapView

Modify your view by adding the xmlns:maps="nativescript-google-maps-sdk" namespace to your <Page> tag, then use the <maps:mapView /> tag to create the MapView:

<!-- /app/main-page.xml -->

<Page 
    xmlns="http://www.nativescript.org/tns.xsd"
    xmlns:maps="nativescript-google-maps-sdk"
>
    <GridLayout>
        <maps:mapView
            latitude="{{ latitude }}"
            longitude="{{ longitude }}"
            zoom="{{ zoom }}"
            bearing="{{ bearing }}" 
            tilt="{{ tilt }}"
            mapAnimationsEnabled="{{ mapAnimationsEnabled }}"
            padding="{{ padding }}"
            mapReady="onMapReady"  
            markerSelect="onMarkerSelect"
            markerBeginDragging="onMarkerBeginDragging"
            markerEndDragging="onMarkerEndDragging"
            markerDrag="onMarkerDrag"
            cameraChanged="onCameraChanged" 
            cameraMove="onCameraMove"
        />
    </GridLayout>
</Page>

Properties

The following properties are available for adjusting the camera view:

Property	Description and Data Type
`latitude`	Latitude, in degrees: `number`
`longitude`	Longitude, in degrees: `number`
`zoom`	Zoom level (described here): `number`
`bearing`	Bearing, in degrees: `number`
`tilt`	Tilt, in degrees: `number`
`padding`	Top, bottom, left and right padding amounts, in Device Independent Pixels: `number[]` (array)
`mapAnimationsEnabled`	Whether or not to animate camera changes: `Boolean`

Events

The following events are available:

Event	Description
`mapReady`	Fires when the MapView is ready for use
`myLocationTapped`	Fires when the 'My Location' button is tapped
`coordinateTapped`	Fires when a coordinate is tapped on the map
`coordinateLongPress`	Fires when a coordinate is long-pressed on the map
`markerSelect`	Fires when a marker is selected
`markerBeginDragging`	Fires when a marker begins dragging
`markerEndDragging`	Fires when a marker ends dragging
`markerDrag`	Fires repeatedly while a marker is being dragged
`markerInfoWindowTapped`	Fires when a marker's info window is tapped
`markerInfoWindowClosed`	Fires when a marker's info window is closed
`shapeSelect`	Fires when a shape (e.g., `Circle`, `Polygon`, `Polyline`) is selected (Note: you must explicity configure `shape.clickable = true;` for this event to fire)
`cameraChanged`	Fires after the camera has changed
`cameraMove`	Fires repeatedly while the camera is moving
`indoorBuildingFocused`	Fires when a building is focused on (the building currently centered, selected by the user or by the location provider)
`indoorLevelActivated`	Fires when the level of the focused building changes

Native Map Object

The MapView's gMap property gives you access to the platform's native map object–––consult the appropriate SDK reference on how to use it: iOS | Android

UI Settings

You can adjust the map's UI settings after the mapReady event has fired by configuring the following properties on mapView.settings:

Property	Description and Data Type
`compassEnabled`	Whether the compass is enabled or not: `Boolean`
`indoorLevelPickerEnabled`	Whether the indoor level picker is enabled or not: `Boolean`
`mapToolbarEnabled`	Android only Whether the map toolbar is enabled or not: `Boolean`
`myLocationButtonEnabled`	Whether the 'My Location' button is enabled or not: `Boolean`
`rotateGesturesEnabled`	Whether the compass is enabled or not: `Boolean`
`scrollGesturesEnabled`	Whether map scroll gestures are enabled or not: `Boolean`
`tiltGesturesEnabled`	Whether map tilt gestures are enabled or not: `Boolean`
`zoomGesturesEnabled`	Whether map zoom gestures are enabled or not: `Boolean`
`zoomControlsEnabled`	Android only Whether map zoom controls are enabled or not: `Boolean`

Styling

Use gMap.setStyle(style); to set the map's styling (Google Maps Style Reference | Styling Wizard).

Angular

Use this.mapView.setStyle(<Style>JSON.parse(this.styles)); inside of the onMapReady event handler. In this example, this.mapView is the MapView object and this.styles is a reference to a JSON file that was created using the Styling Wizard. The <Style> type was imported from the plugin as { Style }.

Basic Example

//  /app/main-page.js

var mapsModule = require("nativescript-google-maps-sdk");

function onMapReady(args) {
    var mapView = args.object;
    
    console.log("Setting a marker...");
    var marker = new mapsModule.Marker();
    marker.position = mapsModule.Position.positionFromLatLng(-33.86, 151.20);
    marker.title = "Sydney";
    marker.snippet = "Australia";
    marker.userData = { index : 1};
    mapView.addMarker(marker);
    
    // Disabling zoom gestures
    mapView.settings.zoomGesturesEnabled = false;
}

function onMarkerSelect(args) {
    console.log("Clicked on " +args.marker.title);
}

function onCameraChanged(args) {
    console.log("Camera changed: " + JSON.stringify(args.camera)); 
}

function onCameraMove(args) {
    console.log("Camera moving: "+JSON.stringify(args.camera));
}

exports.onMapReady = onMapReady;
exports.onMarkerSelect = onMarkerSelect;
exports.onCameraChanged = onCameraChanged;
exports.onCameraMove = onCameraMove;

Custom Info Windows (Beta)

Warning

if you are using NS7 infoWindowTemplate won't work from a xml file! a temporary solution will be declaring infoWindow Template from the code behind like this :

var mapView = null;

export function onMapReady(args) {
    mapView = args.object;
    mapView.infoWindowTemplate = `<StackLayout orientation="vertical" width="200" height="150" >
        <Label text="{{title}}" className="title" width="125"   />
        <Label text="{{snippet}}" className="snippet" width="125"   />
        <Label text="{{'LAT: ' + position.latitude}}" className="infoWindowCoordinates"  />
        <Label text="{{'LON: ' + position.longitude}}" className="infoWindowCoordinates"  />
    </StackLayout>`;
}

To use custom marker info windows, define a template in your view like so:

<!-- /app/main-page.xml -->
<Page 
    xmlns="http://www.nativescript.org/tns.xsd"
    xmlns:maps="nativescript-google-maps-sdk"
>
  <GridLayout>
       <maps:mapView mapReady="onMapReady">
            <!-- Default Info Window Template -->       		
            <maps:mapView.infoWindowTemplate>
                <StackLayout orientation="vertical" width="200" height="150" >
                    <Label text="{{title}}" className="title" width="125"   />
                    <Label text="{{snippet}}" className="snippet" width="125"   />
                    <Label text="{{'LAT: ' + position.latitude}}" className="infoWindowCoordinates"  />
                    <Label text="{{'LON: ' + position.longitude}}" className="infoWindowCoordinates"  />
                </StackLayout>
            </maps:mapView.infoWindowTemplate>
            <!-- Keyed Info Window Templates -->   
            <maps:mapView.infoWindowTemplates>
                <template key="testWindow">
                    <StackLayout orientation="vertical" width="160" height="160" >
                        <Image src="res://icon" stretch="fill"  height="100" width="100" className="infoWindowImage" />
                        <Label text="Let's Begin!" className="title" />
                    </StackLayout>
                </template>
            </maps:mapView.infoWindowTemplates>
        </maps:mapView>
  </GridLayout>
</Page>

...and set the infoWindowTemplate property like so:

var marker = new mapsModule.Marker();
marker.infoWindowTemplate = 'testWindow';

This will configure the marker to use the info window template with the given key. If no template with that key is found, then it will use the default info window template.

** Known issue: remote images fail to display in iOS info windows (local images work fine)

Usage with Angular

See Angular demo code included here

// /app/map-example.component.ts

import {Component, ElementRef, ViewChild} from '@angular/core';
import {registerElement} from "nativescript-angular/element-registry";

// Important - must register MapView plugin in order to use in Angular templates
registerElement("MapView", () => require("nativescript-google-maps-sdk").MapView);

@Component({
    selector: 'map-example-component',
    template: `
    <GridLayout>
        <MapView (mapReady)="onMapReady($event)"></MapView>
    </GridLayout>
    `
})
export class MapExampleComponent {

    @ViewChild("MapView") mapView: ElementRef;

    //Map events
    onMapReady = (event) => {
        console.log("Map Ready");
    };
}

Angular 8 Support

If you are using Angular 8, there is a temporary fix needed for the @ViewChild directive, and will not be needed in Angular 9:

@ViewChild("MapView", {static: false}) mapView: ElementRef;

Clustering Support (Issue #57)

There is a seperate plugin in development thanks to @naderio: see nativescript-google-maps-utils.
