Contact support@basic4ppc.com and ask to get a downloadlink for this jar. Maybe it is available in forum somewhere but i can´t remember if and where.

In fact it is google who changed the SDK and the Library must be updated to work with the newest Mavenrepositories.

Notifications will not work properly with B4A v7.8 as it will not handle the requirements added in Android 8+. See the targetSdkVersion tutorial for more information.

The app will crash on Android 8+ devices when targetSdkVersion is set to 26.
The latest version of the library is attached.

Reload the page and use the link i used. I do NOT search and post it again

Note that we are talking about Firebaseintegration! So the firebaseintegrationtutorial should be the place to look for it, right?

Do not check Google Map Tutorial or Bluetooth Tutorial. They will not help.

How dfo you expect we could help you here with this LESS Infos you provide?
Upload a small project which shows the issue.

I´m out here: i´m not interested to further try to help.

Theme.IAPTheme comes from admob. Are you using addmob and also added admob to your project? I guess yes as you are adding the Snippet for ADS.
