Firebase notification is a internal library.
From the xml in the internal library folder.

<version>1.21</version>

Click to expand...

I suggest to update your B4A.

I can't buy a new version whenever I have a bug....
Why can't I use v7.8?

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.

While you can probably fix this error, once you get it working the app will crash when it receives a message while it is in the background. You must use B4A v8+ with the automatic foreground mode feature.

You have updated the manifest to use the new Snippets? Note that you are now using B4A 8+ and need other Snippets than in the past.

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.

You DID READ the error?
You DID realized that you need the google-services.json in your projectfolder (as it was needed in the past!) but it is not there?

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.
