Proguard issue with Mopub and Google Play Service 8.4.0




I’m experiencing an issue with Proguard in my project which uses Mopub SDK 4.4.1 and Google Play Service 8.4.0.

Error: Uncaught translation error: cannot be cast to
Possible causes for this unexpected error include:

In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

It seems that Mopub SDK still depends on Play Service 7.8.0. Is there any workaround for this issue as I need to use the newest features in Google Analytics v4?


Hi @tvkkpt,

Thanks for reaching out! There is currently no workaround for this. However, we are working to update our Google adapters. I would recommend watching our GitHub page so you are notified of updates.
