AdMob

The admob allows you to display adverts in your app, using your account from AdMob by Google. RNFirebase allows you to display Banners, Interstitials, NativeExpress Ads & Rewarded Videos.

Initialize

Before using any AdMob feature, ensure you call the initialize method. This only needs to be done once per the apps lifecycle. Initialize takes your AdMob App ID, where you can find on your AdMob dashboard.

For testing purposes, you can use AdMobs test app ID "ca-app-pub-3940256099942544~3347511713".

firebase.admob().initialize("ca-app-pub-3940256099942544~3347511713");

API

Banner

AdMob Banners in RNFirebase are exported as a usable React component, allowing you to integrate it easily into your existing app very easily.

Props

Prop	Type	Default	Description
size	string (See Sizes)	SMART_BANNER	Returns a sized banner (automatically sets View style)
unitId	string		Your AdMob banner unit ID.
request	AdRequest	new AdRequest().addTestDevice().build()	An instance of AdRequest to load with the Banner
onAdLoaded	function		Called when an ad is received.
onAdOpened	function		Called when an ad opens an overlay that covers the screen.
onAdLeftApplication	function		Called when an ad leaves the application (e.g., to go to the browser).
onAdClosed	function		Called when the user is about to return to the application after clicking on an ad.
onAdFailedToLoad	function		Called when an ad request failed. See Error Handling

Example

const Banner = firebase.admob.Banner;
const AdRequest = firebase.admob.AdRequest;
const request = new AdRequest();
request.addKeyword('foobar');
...
render() {
  return (
    <Banner
      size={"LARGE_BANNER"}
      request={request.build()}
      onAdLoaded={() => {
        console.log('Advert loaded and is now visible');
      }}
    />
  );
}

Interstitial

An interstitial is a full screen advert which creates a new activity on top of React. As they need to be controlled, allowing the developer to choose when to display them they're not available as a component. Instead they're controlled via method calls.

A single interstitial instance can only be shown once. If you want to display another, create a new one.

To request an interstitial from AdMob, the loadAd method must be called with an instance of AdRequest (see below for full API):

Methods

Method	Description
loadAd(AdRequest)	Loads an advert with request config
on(event, callback)	Listens to advert events. See Event Types for more information.
isLoaded()	Returns a boolean value as to whether the advert is loaded and ready to show.
show()	Show the advert on the device

Example

const advert = firebase.admob().interstitial('ca-app-pub-3940256099942544/1033173712');

const AdRequest = firebase.admob.AdRequest;
const request = new AdRequest();
request.addKeyword('foo').addKeyword('bar');

// Load the advert with our AdRequest
advert.loadAd(request.build());

advert.on('onAdLoaded', () => {
  console.log('Advert ready to show.');
});

// Simulate the interstitial being shown "sometime" later during the apps lifecycle
setTimeout(() => {
  if (advert.isLoaded()) {
    advert.show();
  } else {
    // Unable to show interstitial - not loaded yet.
  }
}, 1000);

Native Express

An AdMob Native Express advert is much like a standard Banner, except it can be integrated seamlessly into your app using user predefined styling (background color, positions, font size etc). Native Express adverts are exported as a usable React component.

Props

Prop	Type	Default	Description
size	string (See Sizes)	SMART_BANNER	TODO
unitId	string		Your AdMob banner unit ID.
request	AdRequest	new AdRequest().addTestDevice().build()	An instance of AdRequest to load with the Banner
video	AdRequest	new VideoOptions().build()	An instance of AdRequest to load with the Banner
onAdLoaded	function		Called when an ad is received.
onAdOpened	function		Called when an ad opens an overlay that covers the screen.
onAdLeftApplication	function		Called when an ad leaves the application (e.g., to go to the browser).
onAdClosed	function		Called when the user is about to return to the application after clicking on an ad.
onAdFailedToLoad	function		Called when an ad request failed. See Event PropTypes for more information.
onVideoEnd	function		Called if the advert video has ended (only called if the advert has a video).

Usage

const Banner = firebase.admob.Banner;
const NativeExpress = firebase.admob.NativeExpress;
const AdRequest = firebase.admob.AdRequest;

const request = new AdRequest();
request.addKeyword('foobar');
...
render() {
  return (
    <NativeExpress
      size={"300x400"}
      request={request.build()}
      onAdLoaded={() => {
        console.log('Advert loaded and is now visible');
      }}
    />
  );
}

Rewarded Video

A rewarded video allows you to display a video to a user, whereby they're able to watch it to gain "rewards", or skip it and receive nothing. For example, when a user completes a level on your gaming app, show them a video which will give them in-game credit.

A single rewarded video instance can only be shown once. If you want to display another, create a new one.

?> It's recommended you begin loading the video as soon as possible.

To request an Rewarded Video from AdMob, the loadAd method must be called with an instance of AdRequest (see below for full API):

Methods

Method	Description
loadAd(AdRequest)	Loads an advert with request config
on(event, callback)	Listens to advert events. See Event Types
isLoaded()	Returns a boolean value as to whether the advert is loaded and ready to show
show()	Show the advert on the device

Example

const advert = firebase.admob().rewarded('ca-app-pub-3940256099942544/1033173712');

const AdRequest = firebase.admob.AdRequest;
const request = new AdRequest();
request.addKeyword('foo').addKeyword('bar');

// Load the advert with our AdRequest
advert.loadAd(request.build());

advert.on('onAdLoaded', () => {
  console.log('Advert ready to show.');
});

advert.on('onRewarded', (event) => {
  console.log('The user watched the entire video and will now be rewarded!', event);
});

...

onLevelComplete()
  .then(() => {
    if (advert.isLoaded()) {
      advert.show();
    } else {
      // skip...
    }
  });

AdRequest

The AdRequest class is used to create an object to be passed to each advert request. The request is handled on AdMob, and returns adverts tailored to the request options provided.

!> If no AdRequest is sent, the default request calls addTestDevice. Therefore, ensure a custom AdRequest object is passed through in production.

build()

Builds the current request for AdMob to handle.

addTestDevice(device?: string)

Sets a device ID as a test device. If no device string is passed, a default emulator id is passed.

addKeyword(keyword: `string`)

Add a new keyword to relate the advert to.

setBirthday(date: `Date`)

Sets the user's birthday for targeting purposes.

setGender(gender: `male | female | unknown`)

Sets the user's gender for targeting purposes.

setLocation()

Sets the user's location for targeting purposes.

setRequestAgent(requestAgent: `string`)

Sets the request agent string to identify the ad request's origin. Third party libraries that reference the Mobile Ads SDK should call this method to denote the platform from which the ad request originated. For example, if a third party ad network called "CoolAds network" mediates requests to the Mobile Ads SDK, it should call this method with "CoolAds"

setContentUrl(url: `string`)

Sets the content URL for targeting purposes.

[android] setIsDesignedForFamilies(forFamilies: `boolean`)

If you set this value to true, you indicate that your app requires that the ad request should return a Designed for Families-compliant ad.

If you set this value to false, you indicate that your app does not require that the ad request should return a Designed for Families-compliant ad.

tagForChildDirectedTreatment(forChildren: `boolean`)

VideoOptions

The VideoOptions class is used to create an object to be passed through to each advert request. If the advert returns a video, the options are used when displaying it on the application.

?> Currently NativeExpress only accepts VideoOptions. If no VideoOptions are sent, the default options call setStartMuted(true).

build()

Builds the current options for AdMob to handle.

setStartMuted(muted: `boolean`)

If true, any returned video will not play sound when it starts. The end user can manually enable sound on the advert interface.

Prop Types

size: `String`

Sets the size of an Advert. Can be one of the following or a custom size:

Size	Description
BANNER	Mobile Marketing Association (MMA) banner ad size (320x50 density-independent pixels).
FULL_BANNER	Interactive Advertising Bureau (IAB) full banner ad size (468x60 density-independent pixels).
LARGE_BANNER	Large banner ad size (320x100 density-independent pixels).
LEADERBOARD	Interactive Advertising Bureau (IAB) leaderboard ad size (728x90 density-independent pixels).
MEDIUM_RECTANGLE	Interactive Advertising Bureau (IAB) medium rectangle ad size (300x250 density-independent pixels).
SMART_BANNER	A dynamically sized banner that is full-width and auto-height.

To specify a custom size, pass a string with the width and height split by an "x" (follows the Regex pattern ([0-9]+)x([0-9]+)), e.g 320x150

?> Requesting an advert with a size which does not exist on the AdMob servers will return admob/error-code-internal-error.

unitId: `String`

The unit ID for the banner. Defaults to the testing unitId provided by Google for the advert type.

request: `AdRequest`

A built AdRequest object returned from AdRequest.build().

video: `VideoOptions`

A built VideoOptions object returned from VideoOptions.build().

Events

Every advert returns common event types. On component based adverts (e.g. Banner) they're available as props and on instance based adverts (e.g. Interstitial) they're available via the on method.

onAdLoaded(config: `Object`)

!> The config is not provided for Interstitial or Rewarded Video adverts.

On successful response from the AdMob servers. This is also called when a new banner is automatically loaded from the AdMob servers if the current one expires.
