Android Game CRASHES after updating PROGUARD

I was having issues packaging my game for production so I updated proguard to 6.0.3.

The game packages now, but when I put it on my phone it crashes on startup. However, I can deploy it, and it works perfectly fine. It’s only when packaging and moving over the APK to my phone.

I have 1 plugin I am using (It is for ads). Here is what my logcat says when the game crashes :

“Caused by: java.lang.ClassNotFoundException: Didn’t find class “com.google.android.gms.ads.reward.RewardedVideoAdListener” on path: DexPathList”

“Caused by: java.lang.ClassNotFoundException: Didn’t find class “com.google.android.gms.ads.AdListener” on path: DexPathList”

Before updating proguard, the packaging process went smoothly and ran just fine. It wasn’t until yesterday that the packaging process would give me an error. I believe that was because proguard was not a high enough version to support Java 8. So I upgraded proguard. Now this happens. I am stumped. I have spent all day today and yesterday trying to fix this. 10+ hours each day. No luck.

I am hoping someone here has advice that can help.

for those looking for an answer, you’d need to add the class to the exception list in proguard
