Android – room smashed release

I use room in my project and everything goes well, but it will give me this error when I try to run it at release time

Cause: java.lang.runtimeexception: unable to find the implementation of via.rider.repository.ai_ Impl does not exist

I see that all the problems are about build. Config, but I did configure the annotationprocessor

// Android Room
    implementation "android.arch.persistence.room:runtime:$roomVersion"
    annotationProcessor "android.arch.persistence.room:compiler:$roomVersion"
    implementation "android.arch.persistence.room:rxjava2:$roomVersion"
    implementation 'io.reactivex.rxjava2:rxandroid:2.0.2'

What could it be?

resolvent:

I'm sure room is trying to generate the database schema instead of your class. It will only get some confusing pulp. Try adding:

-keep class via.rider.repository.** { *; } 

Go to your proguard-rule.pro
