java.lang.IllegalAccessError: Class ref in pre-verified class resolved to unexpected implementationindicates that the class (one of your classes that contains a@Subscribedannotation) in question seems to be different in your final APK (specifically the dex file).This may be related to multi-dex or if you somehow included these classes twice as a dependency.

Thanks. Probably found problem. We rewrote EventBusBuilder and EventBus classes, added some logs. EventBusBuilder constructor is not public, se we put custom classes in
org.greenrobot.eventbuspackage. Maybe it caused problem.greenrobot-team commentedon Mar 27, 2017
Alright, closing this then. -ut

Now, I faced the same problem as above,can you tell me why and what I should do with it? thanks a lot
DeanKersting commentedon Apr 4, 2019
This is usually happened when call Eventbus.register(subscribe)，subscribe Class is belonged to a different dex which is not THE dex Eventbus class belonged to!So you can add Eventbus ref(such as Eventbus.class.getName()) in your subscribe class to prevent it being marked as 'class_preverified' by Dalvik VM,ART VM don't have this problem),it will solve ur problem!

juanlabrador commentedon Jan 28, 2020

juanlabrador commentedon Feb 6, 2020
It happens when Dexguard is active, How I can add Eventbus ref in subscribe class?
soochun-deali commentedon Mar 14, 2020
same here with after applying dexguard
soochun-deali commentedon Mar 19, 2020
fix with below rule added
dexguard version : 8.6.06
eventbus version : 3.2.0
-keepnames class org.greenrobot.eventbus.**
-keep class org.greenrobot.eventbus.** { *; }
