B4A Library FirebaseAdMob - Admob ads integrated with Firebase backend

Not open for further replies.
Use FirebaseAdMob2 instead: https://www.b4x.com/android/forum/threads/firebaseadmob2-google-mobile-ads-sdk-v20.129609/

This library required B4A v6+.

This library allows showing AdMob ads. It is integrated with Firebase services so you can better track and analyze the results.

It supports banner ads and interstitial ads (full screen ads).

First you need to follow the Firebase integration tutorial: https://www.b4x.com/android/forum/threads/integrating-firebase-services.67692/
Make sure to include the Ads manifest snippet.

Full example that shows a banner ad and an interstitial ad when clicking on the activity:
Sub Process_Globals

End Sub

Sub Globals
   Private BannerAd As AdView
   Private IAd As InterstitialAd
End Sub

Sub Activity_Create(FirstTime As Boolean)
   BannerAd.Initialize2("BannerAd", "ca-app-pub-3940256099942544/6300978111", BannerAd.SIZE_SMART_BANNER)
   Dim height As Int
   If GetDeviceLayoutValues.ApproximateScreenSize < 6 Then
    If 100%x > 100%y Then height = 32dip Else height = 50dip
    height = 90dip
   End If
   Activity.AddView(BannerAd, 0dip, 100%y - height, 100%x, height)
   IAd.Initialize("iad", "ca-app-pub-3940256099942544/1033173712")
End Sub

Sub Activity_Click
   If IAd.Ready Then IAd.Show
End Sub

Sub IAD_AdClosed
   IAd.LoadAd 'prepare a new ad
End Sub
These are test ids and they will show test ads.

Edit: It is also required to request user consent for personalized ads. See this tutorial: https://www.b4x.com/android/forum/threads/firebaseadmob-and-user-consent.93347/#post-590593

V1.60 - Few new requirements, explained here: https://www.b4x.com/android/forum/threads/firebaseadmob-v1-6.108552/
V1.50 - Adds support for requesting consent.
V1.31 - Fixes an issue related to InMobi mediation ads.
V1.30 - Adds support for rewarded video ads: https://www.b4x.com/android/forum/threads/firebaseadmob-rewarded-video-ads.71430/
V1.20 - Adds support for native ads: https://www.b4x.com/android/forum/t...integrated-with-firebase-backend.67710/page-3

Currently it only supports banner ads and interstitial ads.

If anyone likes I can post the source code of this library.

can you plz share the source so maybe we can extend it to support the rest ads?

first impressions...

it works ;) well done!

it's bloated > app went from 1.4Mb to 2.34Mb compared to the old admob+googleplayservices method.

not sure if we can exclude some of the stuff that's not required when just using the ads part?

I'm not sure about the benefits of this FireBase thing, maybe it reflects tomorrow when the data from my tests are visible in the reports.

Hi @Erel
i m received this email from google admob, i dont know if cause any changes here.

A AdMob tem o compromisso de fornecer a você as soluções de monetização mais eficazes. À medida que inovamos, é importante aproveitar as tecnologias mais recentes para incrementar nossa plataforma. Como parte desse movimento, desativaremos as versões 6.4.1 e anteriores do SDK dos anúncios para dispositivos móveis do Google no Android em 15 de setembro de 2016.
Para garantir a veiculação dos seus anúncios depois de 15 de setembro de 2016, faça upgrade para o SDK dos anúncios para dispositivos móveis do Google 7.0.0 ou posterior.
Os SDKs dos anúncios para dispositivos móveis do Google mais recentes têm muito mais vantagens para você:
  • Atualizações automáticas contínuas. Os usuários recebem as alterações no SDK dos anúncios para dispositivos móveis do Google no Android de forma contínua por meio dos serviços do Google Play para que você possa usar seu tempo no que é importante
    • Você não precisará passar tempo atualizando seus aplicativos com as versões mais recentes do SDK dos anúncios sempre que ele for alterado
    • Os usuários também receberão os novos recursos e as correções de bugs por meio de atualizações automáticas
  • Melhores experiências do usuário. O gerenciamento das atualizações dos aplicativos será mais fácil para os usuários, pois algumas melhorias serão recebidas automaticamente em segundo plano.
Para fazer upgrade do seu SDK, adicione a versão mais recente dos serviços do Google Play (em dependências) no seu arquivo de configuração do Gradle Build. Por exemplo, veja a seguir a adição da v9.0:
apply plugin: 'com.android.application'
dependencies {
    compile 'com.google.android.gms:play-services:9.0.2'

Fique atento para mais atualizações e dicas.
Equipe da AdMob

AdMob is committed to providing you the most effective monetization solutions. As we innovate, it is important to use the latest technologies to enhance our platform. As part of this move, we will disable the 6.4.1 and earlier versions of Ads SDK for Google mobile on Android on September 15, 2016.
To ensure your ads run after September 15, 2016, upgrade to the SDK mobile ads Google 7.0.0 or later.
SDKs ads for the latest Google mobile devices have much more advantages for you:
Continuous automatic updates. Users receive the changes in Ads SDK for Google mobile on Android continuously through the Google Play services so you can use your time on what's important
You do not have to spend time updating your applications with the latest versions of the SDK ads whenever it changes
Users also receive new features and bug fixes through Automatic Updates
Best user experience. The management of the application updates will be easier for users because some improvements will be received automatically in the background.
To upgrade your SDK add the latest version of Google Play services (facilities) in your Gradle Build configuration file. For example, see the following addition of v9.0:

apply plugin: 'com.android.application'
dependencies {
    compile 'com.google.android.gms:play-services:9.0.2'

Stay tuned for more updates and tips.

this will change something in this library? or will not change anything?

ps: google play services now is REV 31

Hi Erel,

I also received the email from AdMob advising of the impending deprecation of SDK 6.4.1. I have been using the mwAdmobInterstitial2 library for a long time & it works great, however I don't know what version of the AdMob SDK it uses - so I thought I'd switch to AdMob through Firebase. I'm also using the Google Play Services library written by NFOBoy for leaderboards & achievements (I know it's an old library, but it has worked well for me) & now after switching Admob to Firebase, I get the following error when I compile the app:

B4A version: 6.00

class file for com.google.android.gms.games.achievement.OnAchievementsLoadedListener not found

I'm guessing that there's some kind of conflict between the version of Google Play Services that Firebase is using & the version (v14 I think) that NFOBoy's library is using?
