API Keys

To use the Google Maps SDK on any platform, API keys associated with an account with billing enabled are required. These can be obtained from the Google Cloud Console. This is required for all three platforms, Android, iOS, and Javascript. Additional information about obtaining these API keys can be found in the Google Maps documentation for each platform.

iOS

The Google Maps SDK supports the use of showing the users current location via enableCurrentLocation(bool). To use this, Apple requires privacy descriptions to be specified in Info.plist:

  • NSLocationAlwaysUsageDescription (Privacy - Location Always Usage Description)
  • NSLocationWhenInUseUsageDescription (Privacy - Location When In Use Usage Description)

Read about Configuring Info.plist in the iOS Guide for more information on setting iOS permissions in Xcode.

The main Google Maps SDK now supports running on simulators on Apple Silicon Macs, however, a dependency from Google called Google-Maps-iOS-Utils does not yet support Apple Silicon. This is requires a new release of the library from Google. If you are developing on an Apple Silicon Mac, building and running on physical devices is still supported and is the recommended approach.

A workaround on Apple Silicon Macs if you want/need to use the simulator is adding the following line to your Podfile in the target 'App' section after the # Add your Pods here line:

pod 'Google-Maps-iOS-Utils', :git => 'https://github.com/googlemaps/google-maps-ios-utils.git', :commit => '637954e5bcb2a879c11a6f2cead153a6bad5339f'

Android

The Google Maps SDK for Android requires you to add your API key to the AndroidManifest.xml file in your project.

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

To use certain location features, the SDK requires the following permissions to also be added to your AndroidManifest.xml:

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

Variables

This plugin will use the following project variables (defined in your app's variables.gradle file):

  • googleMapsPlayServicesVersion: version of com.google.android.gms:play-services-maps (default: 18.1.0)
  • googleMapsUtilsVersion: version of com.google.maps.android:android-maps-utils (default: 3.4.0)
  • googleMapsKtxVersion: version of com.google.maps.android:maps-ktx (default: 3.4.0)
  • googleMapsUtilsKtxVersion: version of com.google.maps.android:maps-utils-ktx (default: 3.4.0)
  • kotlinxCoroutinesVersion: version of org.jetbrains.kotlinx:kotlinx-coroutines-android and org.jetbrains.kotlinx:kotlinx-coroutines-core (default: 1.6.4)
  • androidxCoreKTXVersion: version of androidx.core:core-ktx (default: 1.10.0)
  • kotlin_version: version of org.jetbrains.kotlin:kotlin-stdlib-jdk7 (default: 1.8.20)

Usage

The Google Maps Jigra plugin ships with a web component that must be used to render the map in your application as it enables us to embed the native view more effectively on iOS. The plugin will automatically register this web component for use in your application.

For Angular users, you will get an error warning that this web component is unknown to the Angular compiler. This is resolved by modifying the module that declares your component to allow for custom web components.

import { CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';

@NgModule({
  schemas: [CUSTOM_ELEMENTS_SCHEMA]
})

Include this component in your HTML and assign it an ID so that you can easily query for that element reference later.

<jigra-google-map id="map"></jigra-google-map>

On Android, the map is rendered beneath the entire webview, and uses this component to manage its positioning during scrolling events. This means that as the developer, you must ensure that the webview is transparent all the way through the layers to the very bottom. In a typically Family application, that means setting transparency on elements such as FmlContent and the root HTML tag to ensure that it can be seen. If you can't see your map on Android, this should be the first thing you check.

On iOS, we render the map directly into the webview and so the same transparency effects are not required. We are investigating alternate methods for Android still and hope to resolve this better in a future update.

The Google Map element itself comes unstyled, so you should style it to fit within the layout of your page structure. Because we're rendering a view into this slot, by itself the element has no width or height, so be sure to set those explicitly.

jigra-google-map {
  display: inline-block;
  width: 275px;
  height: 400px;
}

Next, we should create the map reference. This is done by importing the GoogleMap class from the Jigra plugin and calling the create method, and passing in the required parameters.

import { GoogleMap } from '@jigra/google-maps';

const apiKey = 'YOUR_API_KEY_HERE';

const mapRef = document.getElementById('map');

const newMap = await GoogleMap.create({
  id: 'my-map', // Unique identifier for this map instance
  element: mapRef, // reference to the jigra-google-map element
  apiKey: apiKey, // Your Google Maps API Key
  config: {
    center: {
      // The initial position to be rendered by the map
      lat: 33.6,
      lng: -117.9,
    },
    zoom: 8, // The initial zoom level to be rendered by the map
  },
});

At this point, your map should be created within your application. Using the returned reference to the map, you can easily interact with your map in a number of way, a few of which are shown here.

const newMap = await GoogleMap.create({...});

// Add a marker to the map
const markerId = await newMap.addMarker({
  coordinate: {
    lat: 33.6,
    lng: -117.9
  }
});

// Move the map programmatically
await newMap.setCamera({
  coordinate: {
    lat: 33.6,
    lng: -117.9
  }
});

// Enable marker clustering
await newMap.enableClustering();

// Handle marker click
await newMap.setOnMarkerClickListener((event) => {...});

// Clean up map reference
await newMap.destroy();
