Installation ​

To install @nativescript/firebase-admob, run the following command in the root directory of the project:

npm install @nativescript/firebase-admob

Setup Admob for iOS ​

Update your Info.plist file at App_Resources/iOS with a GADApplicationIdentifier key with a string value of your AdMob app ID (identified in the AdMob UI).

<key>GADApplicationIdentifier</key>
<string>ca-app-pub-xxxxxxxxxxxxxxxx~yyyyyyyyyy</string>

For more information about configuring the Info.plist and setting up your App ID, see Update your Info.plist.

Setup Admob for Android ​

Add AdMob App ID (identified in the AdMob UI) to the app's AndroidManifest.xml file, found at App_Resources/Android/src/main. Failure to do so will result in a crash on app launch. Add the ID by adding a <meta-data> tag with name com.google.android.gms.ads.APPLICATION_ID, as shown below. For android:value insert your own AdMob App ID in quotes.

<application>
  <!-- Sample AdMob App ID: ca-app-pub-xxxxxxxxxxxxxxxx~yyyyyyyyyy -->
  <meta-data
    android:name="com.google.android.gms.ads.APPLICATION_ID"
    android:value="ca-app-pub-xxxxxxxxxxxxxxxx~yyyyyyyyyy"
  />
</application>

See step 3. of Configure your app for more information about configuring AndroidManifest.xml and setting up the App ID.

Use @nativescript/firebase-admob ​

To use the @nativescript/firebase-admob plugin, follow the steps below:

1. Initialize the Mobile Ads SDK ​

Before loading ads, initialize the Mobile Ads SDK by calling the static init method on the Admob class. Call this method once, ideally right before the app boots, in the main.ts file.

import { Admob } from '@nativescript/firebase-admob'

Admob.init()

2. Add your preferred ad format to the app ​

The Mobile Ads SDK is now imported and you're ready to implement an ad. Click any of the links below to get detailed implementation steps for your desired ad format.

• Banner
• Interstitial (full-screen)
• Native
• Rewarded

Banner ads ​

Banner ads are rectangular ads that appear at the top or bottom of the device screen. They stay on screen while users are interacting with the app, and can refresh automatically after a certain period. If you're new to mobile advertising, they're a great place to start.

Testing Banner ads in development mode ​

To enable dedicated test ad unit ID for banners, visit the links below:

• Android demo units
• iOS demo units

Below are examples of adding a Banner ad in several NativeScript flavors.

Add Banner ad in NativeScript Core ​

Register the plugin namespace in the Page element under a prefix(ui for example), access the BannerAd view from the namespace via the prefix and add it to your XML.

The BannerAd requires the following attributes to be set:

• unitId
• BannerAdSize: You can set this value in the callback function of the layoutChanged event. For more information, see Customize the banner ad size
• height and width

<Page xmlns:ui="@nativescript/firebase-admob">
  <StackLayout>
    <ui:BannerAd
      height="100"
      width="100"
      unitId="{{bannerAdUnit}}"
      layoutChanged="{{loadBanner}}"
    />
  </StackLayout>
  <!-- ... -->
</Page>

import { BannerAdSize } from '@nativescript/firebase-admob'

export function loadBanner(args) {
  const banner = args.object
  banner.size = new BannerAdSize(100, 100)
  banner.load()
}

Add Banner ad in NativeScript Angular ​

Register the BannerAd view by adding its AdmobModule to the imports array of the @NgModule decorator of the component where you want to use the view.

import { AdmobModule } from '@nativescript/firebase-admob/angular';

@NgModule({
    imports: [
    AdmobModule
    ],
    declarations: [
        AppComponent
    ],
    bootstrap: [AppComponent]
})

Next, add the BannerAd view to HTML. The BannerAd requires the following attributes to be set:

• unitId
• BannerAdSize: You can set this value in the callback function of the layoutChanged event. For more information, see Customize the banner ad size
• height and width

<BannerAd
  height="100"
  width="100"
  [unitId]="bannerAdUnit"
  (layoutChanged)="bannerLoaded($event)"
>
</BannerAd>

Add Banner ad in NativeScript Vue ​

Register the BannerAd view in the app.ts file as follows:

import { createApp } from 'nativescript-vue'
import Admob from '@nativescript/firebase-admob/vue'
import Home from './components/Home.vue'

const app = createApp(Home)
app.use(Admob)

And then add it to markup as follows. The BannerAd requires the following attributes to be set:

• unitId
• BannerAdSize: You can set this value in the callback function of the layoutChanged event. For more information, see Customize the banner ad size
• height and width

<BannerAd
  height="100"
  width="100"
  :unitId="bannerAdUnit"
  @layoutChanged="bannerLoaded"
/>

Customize the banner ad size ​

To define a custom banner size, you have 2 options:

• Instantiate the BannerAdSize class with the desired width and height and set it to the size attribute of BannerAd.

import { BannerAdSize } from '@nativescript/firebase-admob'

banner.size = new BannerAdSize(300, 50)

• Set the size to any of the constants of the BannerAdSize class.

The table below lists the available constants and the sizes they represent.

Listen to a banner ad lifecycle events ​

The plugin enables you to listen to different lifecycle events of an ad, such as when an ad is loaded. Register the events handlers before calling the load method.

const bannerView = event.object

// Called when an ad is successfully received.
bannerView.on('adLoaded', (args) => {
  console.log('Ad loaded.')
})

// Called when an ad request failed.
bannerView.on('adFailedToLoad', (args) => {
  console.log('Ad failed to load: ', args.error)
})

// Called when the user removes an overlay that covers the screen.
bannerView.on('adClosed', (args) => {
  console.log('Ad closed.')
})

// Called when an impression occurs on the ad.
bannerView.on('adImpression', (args) => {
  console.log('Ad impression.')
})

// Called when an tap/touch/click occurs on the ad.
bannerView.on('adClicked', (args) => {
  console.log('Ad tapped')
})

Display a banner ad to the user ​

To display a banner ad to the user, get the reference to the BannerAd view and call the load method on it.

bannerView.load()

Add an Interstitial ad ​

Interstitial ads are full-screen ads that cover the interface of an app until closed by the user. They're best used at natural pauses in the flow of an app's execution, such as between levels of a game or just after a task is completed.

Testing Interstitial ads in development ​

• Android demo units
• iOS demo units

Display an Interstitial ad to the user ​

To display an Interstitial ad to the user, follow the steps below:

1. Import the InterstitialAd class from @nativescript/firebase-admob.

import { InterstitialAd } from '@nativescript/firebase-admob'

2. Create an Interstitial ad instance.

Create an Interstitial ad instance by calling the static createForAdRequest on the class. The createForAdRequest method requires an adUnitId and you can optionally pass a RequestOptions object.

import { InterstitialAd } from '@nativescript/firebase-admob'
const ad = InterstitialAd.createForAdRequest(
  'ca-app-pub-xxxxxxxxxxxxxxxx/yyyyyyyyyy'
)

3. Listen to the ad lifecycle events

To listen for the ad lifecycle events, such as when the ad is display or dismissed, call the onAdEvent method on the ad instance, before displaying the ad, passing it a callback function to handle the events.

import { InterstitialAd } from '@nativescript/firebase-admob'

const ad = InterstitialAd.createForAdRequest(
  'ca-app-pub-xxxxxxxxxxxxxxxx/yyyyyyyyyy'
)

ad.onAdEvent((event, error, data) => {
  switch (event) {
    case AdEventType.LOADED:
      break
    case AdEventType.CLOSED:
      break
    case AdEventType.OPENED:
      break
    case AdEventType.IMPRESSION:
      break
    case AdEventType.FAILED_TO_SHOW_FULL_SCREEN_CONTENT:
      break
  }
})

4. Load the ad You load the ad by calling the load method on the ad instance.

import { InterstitialAd } from '@nativescript/firebase-admob'

const ad = InterstitialAd.createForAdRequest(
  'ca-app-pub-xxxxxxxxxxxxxxxx/yyyyyyyyyy'
)

ad.onAdEvent((event, error, data) => {
  switch (event) {
    case AdEventType.LOADED:
      break
    case AdEventType.CLOSED:
      break
    case AdEventType.OPENED:
      break
    case AdEventType.IMPRESSION:
      break
    case AdEventType.FAILED_TO_SHOW_FULL_SCREEN_CONTENT:
      break
  }
})

ad.load()

5. Display the the ad

To display the ad, call the show method on the ad instance. This method is called after the load method.

import { InterstitialAd } from '@nativescript/firebase-admob'

const ad = InterstitialAd.createForAdRequest(
  'ca-app-pub-xxxxxxxxxxxxxxxx/yyyyyyyyyy'
)

ad.onAdEvent((event, error, data) => {
  switch (event) {
    case AdEventType.LOADED:
      break
    case AdEventType.CLOSED:
      ad.show()
      break
    case AdEventType.OPENED:
      break
    case AdEventType.IMPRESSION:
      break
    case AdEventType.FAILED_TO_SHOW_FULL_SCREEN_CONTENT:
      break
  }
})

ad.load()

• Check out an Interstitial ads case study.
• If you haven't already, create your own interstitial ad unit in the AdMob UI.

Native Ads ​

Native ads are ad assets that are presented to users via UI components that are native to the platform. They're shown using the same types of views with which you're already building your layouts, and can be formatted to match the visual design of the user experience in which they live. In coding terms, this means that when a native ad loads, your app receives a NativeAd object that contains its assets, and the app (rather than the Google Mobile Ads SDK) is then responsible for displaying them.

Adding a Native ad in NativeScript Core ​

To add a Native ad to your {N} Core app, follow these steps:

1. Register the plugin namespace under a prefix, ui (this can be any name), with the Page element.

<Page xmlns:ui="@nativescript/firebase-admob">

2. Use the prefix to access the NativeAdView and add it to markup.

<Page xmlns:ui="@nativescript/firebase-admob">
  <ActionBar title="Admob" />
  <StackLayout>
    <ui:NativeAdView height="400" loaded="{{nativeAdLoaded}}" />
  </StackLayout>
</Page>

Testing Native ads in development mode ​

To enable dedicated test ad unit ID, visit the links below:

• Android demo units
• iOS demo units

3. Import the NativeAdLoader class from @nativescript/firebase-admob in the view model file.

import { NativeAdLoader } from '@nativescript/firebase-admob'

The NativeAdLoader class is an interface for managing the the Native ad.

4. Instantiate NativeAdLoader. Create an instance of NativeAdLoader by calling its constructor function. The constructor function accepts 3 parameters. The required adUnitId as the first parameter, optional RequestOptions and NativeAdOptions objects as the second and third parameter, respectively.

const loader = new NativeAdLoader(
  'ca-app-pub-xxxxxxxxxxxxxxxx/yyyyyyyyyy',
  null,
  {
    nativeAdOptions: {
      adChoicesPlacement: AdChoicesPlacement.TOP_RIGHT,
    },
  }
)

5. Listen to the Native ad lifecycle events

To listen to the Native ad lifecycle events, call the onAdEvent method on the NativeAdLoader instance when the NativeAdView has loaded.

<ui:NativeAdView height="400" loaded="{{ nativeAdLoaded }}">
  <GridLayout height="300" width="300">
    <Label id="headLineView" />
    <ui:MediaView id="mediaView" height="100%"/>
    <Label id="bodyView" />
    <Button id="callToActionView" />
  </GridLayout>
</ui:NativeAdView>

function nativeAdLoaded(event) {
  const view = event.object

  loader.onAdEvent((event, error, data) => {
    if (event === NativeAdEventType.LOADED) {
      const ad = data as NativeAd

      const headLineView = view.getViewById('headLineView')
      headLineView.text = ad.headline
      const mediaView = view.getViewById('mediaView')
      view.mediaView = mediaView
      mediaView.mediaContent = ad.mediaContent
      const callToActionButton = view.getViewById('callToActionView')
      view.callToActionView = callToActionButton
      callToActionButton.text = ad.callToAction
      const bodyView = view.getViewById('bodyView')
      bodyView.text = ad.body
      view.nativeAd = ad
      console.log('nativead loaded')
    } else if (event === 'adFailedToLoad') {
      console.log('nativead failed to load', error)
    }
  })
}

6. Display the Native ad To display the Native ad, call the load method on a NativeAdLoader instance.

loader.load()

NativeAdOptions interface ​

A NativeAdOptions object is used to set the following options on the native ad.

AdChoicesPlacement ​

enum AdChoicesPlacement {
  TOP_LEFT = 'topLeft',
  TOP_RIGHT = 'topRight',
  BOTTOM_RIGHT = 'bottomRight',
  BOTTOM_LEFT = 'bottomLeft',
}

videoOptions ​

The videoOptions property is an object with the following properties:

MediaAspectRatio ​

enum MediaAspectRatio {
  LANDSCAPE = 'landscape',
  PORTRAIT = 'portrait',
  SQUARE = 'square',
  ANY = 'any',
}

That's it! Your app is now ready to display native ads.

Rewarded Ads ​

Rewarded ads are ads that users have the option of interacting with in exchange for in-app rewards.

Testing Rewarded ads in development mode ​

To enable dedicated test ad unit ID, visit the links below:

• Android demo units
• iOS demo units

Display a Rewarded ad ​

Follow these steps to display a Rewarded ad:

1. Import the RewardedAd class from @nativescript/firebase-admob.

import { RewardedAd } from '@nativescript/firebase-admob'

2. Create a RewardedAd instance

Create a Rewarded ad instance by calling the createForAdRequest static method on the RewardedAd class and passing it the ad unit id.

import { RewardedAd } from '@nativescript/firebase-admob'

const ad = RewardedAd.createForAdRequest(
  'ca-app-pub-xxxxxxxxxxxxxxxx/yyyyyyyyyy'
)

3. Listen to the ad lifecycle events Before you call the load method to load the ad, call the onAdEvent method passing it a callback function to handle the ad events.

import { RewardedAd } from '@nativescript/firebase-admob'

const ad = RewardedAd.createForAdRequest(
  'ca-app-pub-xxxxxxxxxxxxxxxx/yyyyyyyyyy'
)

ad.onAdEvent((event, error, data) => {
  if (event === AdEventType.LOADED) {
    console.log('rewarded', 'loaded')
  } else if (event === AdEventType.FAILED_TO_LOAD_EVENT) {
    console.error('loading error', error)
  }
})

4. Load the ad To load the ad, call the load method on the RewardAd instance.

import { RewardedAd } from '@nativescript/firebase-admob'

const ad = RewardedAd.createForAdRequest(
  'ca-app-pub-xxxxxxxxxxxxxxxx/yyyyyyyyyy'
)

ad.onAdEvent((event, error, data) => {
  if (event === AdEventType.LOADED) {
    console.log('rewarded', 'loaded')
  } else if (event === AdEventType.FAILED_TO_LOAD_EVENT) {
    console.error('loading error', error)
  }
})
ad.load()

6. Display the ad

To show the ad on the screen, call the show() method on the ad instance.

import { RewardedAd } from '@nativescript/firebase-admob'

const ad = RewardedAd.createForAdRequest(
  'ca-app-pub-xxxxxxxxxxxxxxxx/yyyyyyyyyy'
)

ad.onAdEvent((event, error, data) => {
  if (event === AdEventType.LOADED) {
    console.log('rewarded', 'loaded')
    ad.show()
  } else if (event === AdEventType.FAILED_TO_LOAD_EVENT) {
    console.error('loading error', error)
  }
})
ad.load()

Rewarded ad Events ​

RewardAd emits the following lifecycle events that you can listen to:

ad.onAdEvent((event, error, data) => {
  switch (event) {
    case AdEventType.LOADED:
      break
    case AdEventType.CLOSED:
      break
    case AdEventType.OPENED:
      break
    case AdEventType.IMPRESSION:
      break
    case AdEventType.FAILED_TO_SHOW_FULL_SCREEN_CONTENT:
      break
  }
})

onAdEvent with the event rewarded_earned_reward'is invoked when the user earns a reward. Be sure to implement this and reward the user for watching an ad.

Targeting ​

The RequestConfiguration object collects the global configuration for every ad request and is applied by firebase().admob().setRequestConfiguration().

Child-directed ads setting ​

For child-directed ads setting, read Child-directed setting.

The following example indicates that you want your content treated as child-directed for purposes of COPPA:

import { Admob, RequestConfiguration } from '@nativescript/firebase-admob'

const requestConfiguration: RequestConfiguration = {
  tagForChildDirectedTreatment: true,
}
Admob.getInstance().requestConfiguration = requestConfiguration

Handle ads requests for users under the age of consent ​

To handle ads requests for users under the age of consent, read Users under the age of consent.

The following example indicates that you want TFUA included in your ad request.

import { Admob, RequestConfiguration } from '@nativescript/firebase-admob'

const requestConfiguration: RequestConfiguration = {
  tagForUnderAgeOfConsent: true,
}
Admob.getInstance().requestConfiguration = requestConfiguration

If the tags to enable the Child-directed setting and tagForUnderAgeOfConsentare both set to true, the child-directed setting takes precedence.

Ad content filtering ​

This setting can be set via RequestConfiguration.maxAdContentRating:

AdMob ads returned for these requests have a content rating at or below that level. The possible values for this network extra are based on digital content label classifications, and should be one of the following MaxAdContentRating objects:

• MaxAdContentRating.G
• MaxAdContentRating.PG
• MaxAdContentRating.T
• MaxAdContentRating.MA

The following code configures a RequestConfiguration object to specify that an ad content returned should correspond to a digital content label designation no higher than G:

import {
  Admob,
  MaxAdContentRating,
  RequestConfiguration,
} from '@nativescript/firebase-admob'

const requestConfiguration: RequestConfiguration = {
  maxAdContentRating: MaxAdContentRating.G,
}
Admob.getInstance().requestConfiguration = requestConfiguration
