Hi everyone,

When packaging for Android on UE5.3 there are no errors.
When packaging for Android on UE5.4 it fails with errors in GameActivity.java:

I have a C++ project, so when I comment out the following lines from .Target.cs it works without errors but there is no AdMob support:

		if (Target.Platform == UnrealTargetPlatform.Android)
		{
			ExtraModuleNames.Add("OnlineSubsystemGooglePlay");
			ExtraModuleNames.Add("OnlineSubsystem");
			ExtraModuleNames.Add("AndroidAdvertising");
		}

Does anyone have any idea how to package for Android on UE5.4, with AdMob support?

Thanks.

you got any solution

No, the problem still persists, as described above.

Edit: I just updated to 5.4.2 and I get the same errors. Even commenting out the lines in Target.cs causes the errors. Any ideas?

you got solution bro

virtualyhere · June 18, 2024, 1:17am

If Anyone Face This PRoblem in unreal 5.4 just replace the AdvertisingPlugin inside runtime with older engine version .For me i repplcae with UE5.2 and it show ad

virtualyhere · June 19, 2024, 3:14am

Are you using Android or IOS? The only plugin I have in Advertising (Runtime) is IOSTapJoy.

android

Try updating the code for the AndroidAdvertising_APL.xml. It worked for me on version 5.4.2, with both banner and interstitial ads functioning correctly.

My AndroidAdvertising_APL.xml :
AndroidAdvertising_APL.xml (13.8 KB)

Hi @Lowenmensch,

I followed your instructions and confirm that it now compiles without errors. Thank you!

I still get a bunch of other errors when I submit it to Google Play Console relating to the SDK being old i.e. 18.1.0, instead of 20.0.0+. Any pointers on how to address that?

Again, thank you very much!

Lowenmensch · June 27, 2024, 2:24am

I’m glad to hear that it now compiles without errors!

That’s strange about the SDK version errors from Google Play Console because I already updated the dependencies from 18.1.0 to 22.6.0 in the AndroidAdvertising_APL.xml file I shared. Here’s the section for reference:

dependencies {
implementation(‘com.google.android.gms:play-services-ads:22.6.0’)
implementation(‘com.google.android.gms:play-services-ads-lite:22.6.0’)
}

Hi @Lowenmensch,

You are right again. At first, I used a file from a local copy of UE5.2 and it didn’t work. I confirm that once I used your file, the errors went away.

Thanks again!
