B4A Library FirebaseAdMob v1.6

Erel · Aug 12, 2019

Google has added a few new requirements to AdMob implementation. You must make these changes if you are using the latest versions of Android SDK libraries (firebase-ads 18.1.1+).

Instructions:
2. Find your AdMob app id and add it to the manifest editor:

B4X:

'This is a sample AdMob app id. You need to change it to your id.
AddReplacement($ADMOB_APP_ID$, ca-app-pub-3940256099942544~3347511713)

How to find the id: https://support.google.com/admob/answer/7356431?hl=en

3. Initialize MobileAds in Service_Create of the starter service:

B4X:

Dim MobileAds As MobileAds
MobileAds.Initialize

4. Open Tools - B4A Sdk Manager and update all the recommended items.

If the app immediately crashes then it is likely that the app id is wrong. Start with the sample app id and then change it to your app id.

Library is included as an internal library.

As Google has changed the requirements. Yes if your app(s) is using FirebaseAdMob.

What is the problem and what should i do ?

Erel · Aug 12, 2019

Which version of B4A are you using?

rraswisak · Aug 12, 2019

B4A 9.30

Erel · Aug 12, 2019

Based on the error message you are not using the latest version of firebase-ads. Check it in B4A Sdk Manager. It should be 18.1.1+. Also make sure that the IDE is configured to use the correct SDK - Tools - Configure Paths - android.jar.

rraswisak · Aug 12, 2019

Thank you Erel, i can confirm that the problem was solved right now.

Previous error is because i still use SDK 27 for android.jar in configure path. Now using SDK 28 the app run as usual

dragonguy · Aug 12, 2019

When we using Google-provided test ad units for test our app, so we need add the real one
AdMob app id or testing AdMob app id?

Google-provided test ad app id

B4X:

ca-app-pub-3940256099942544~6300978111

Erel · Aug 12, 2019

I don't think that it matters however you can always use the test app id: ca-app-pub-3940256099942544~3347511713

Scantech · Aug 12, 2019

First Question: AddReplacement($ADMOB_APP_ID$, ca-app-pub-3940256099942544~3347511713)

$ADMOB_APP_ID$ = App ID
ca-app-pub-3940256099942544~3347511713 = ?? Where do i find this??

Second Question: I use

B4X:

Private mwAdInterstitial As InterstitialAd

Do i need

B4X:

Dim MobileAds As MobileAds
MobileAds.Initialize

please read carefully in first post, erel has point to link as your question

Scantech said:
Do i need

i think yes, since you use FirebaseAdMob version 1.6 library

tufanv · Aug 13, 2019

Is this update has to be made or can I continue to use old library with older firebase ?

sorex · Aug 13, 2019

what is this additional piece of code doing and why does it need the placement id when you use it later again to initialize the placement?

is this related to that ads.txt or whatever it was?

Erel · Aug 13, 2019

Technically you can continue to use the old library with the old versions of the firebase items.

Google do recommend to add the app id (and use the latest version of Firebase) so it is probably a good idea to update it soon.

Erel · Aug 13, 2019

sorex said:

It is not the placement id. It is the app id.
It is not related to ads.txt.

In the latest version of AdMob it will throw an error if the app id is missing from the manifest file.

sorex · Aug 13, 2019

ok, thanks.

a lot of updating to do these days if you want to stay conform their 'wishes'.

tufanv · Aug 14, 2019

I have a confusion here. I use more than one interstitial ad ids, some has higher ecpm floor some does not have. With the new version I don't see any place to use these ids. So do I leave the old code on the main module as it is, and just add these piece of code to starter ?

In the latest version of AdMob it will throw an error if the app id is missing from the manifest file.

tufanv · Aug 14, 2019

I did as I mentioned above, My app instantly crashes on launch. My app id is correct. I also tried with the sample app id, I cant even get a log. I will open a new thread for this problem

rraswisak · Aug 14, 2019

in case you has problem as mine, you can try solution at post #8

angel_ · Aug 16, 2019
