You use multiple monetization extensions and possibly other extensions. You might wish to test your Project without them and see whether the Project compiles.

[Taifun]

it looks like you have the error "ERROR: DX returned an error code" which occurs, if you are using several extensions, which use Proguard to obfuscate their code

which extensions are you using?
these extension developers should update their extensions, see also

Updated proguard rules

Hello everyone, If you build your extension from the App Inventor sources and use proguard, you should merge the mit-cml master branch as it includes a change that reduces the chance of classname collisions that fail the dx task when more than one extension is used. Cheers, Evan

and

Keep extension classes in extension package when proguarding

...also appears when libraries conflict. It is easy to guess libs are issue here. I am sure Unity and IAB both requires android-gms lib and that's the reason behind error.

Hello, I'm joining this conversation because I have the same problem. When I load TaifunBluetooth extension together with the TaifunWiFi extension companion doesn't work, and if I try to compile the apk it gives me the error [RunMultidex] ERROR: DX returned an error code. The extensions are updated to the latest version: TaifunBluetooth version 5 and TaifunWiFi version 16. What should I do?
Thanks

When I load TaifunBluetooth extension together with the TaifunWiFi extension companion doesn't work

We detected this issue in October 2023...
The latest version of the bluetooth extension was built in November 2022 and the wifi extension in August 2023, which means, both extensions need to be rebuilt ..

I will provide an update doon...
Thank you

Taifun

[Taifun]

both extensions have been updated meanwhile
you can download them from the download folder
