Hi @sofi-kry, thank you for reporting this!

Could you please provide us with a small reproducible app? I have tried to reproduce the problem in a blank Android app but didn't get the build error that you reported.

Hi @matus-tomlein, thanks for your reply!

In trying to create what you asked, I discovered that the issue was in how we were adding the snowplow dependency. Since the initial integration we've had the @aar at the end of the dependency and removing it fixed the crash 🤷‍♀️

Before:

implementation "com.snowplowanalytics:snowplow-android-tracker:5.4.2@aar"

After:

implementation "com.snowplowanalytics:snowplow-android-tracker:5.4.2"

Thank you!
