Probably https://github.com/square/okhttp/issues/4604 will help, but I didn't try.

buildscript {
    ...
    repositories {
        ...
        maven {
            url 'http://storage.googleapis.com/r8-releases/raw'
        }
    }

    dependencies {
        classpath 'com.android.tools:r8:1.4.57'  // Must be before the Gradle Plugin for Android.
        classpath 'com.android.tools.build:gradle:3.3.1'  // You don't need to upgrade this to use a newer R8 version.
        ...
     }
}

In my case I added OkHttp library and it's Proguard rules. Then removed the library but forgot to remove rules. You can comment or remove these lines from proguard-rules.pro if you removed OkHttp from build.gradle:

### OkHttp.

# JSR 305 annotations are for embedding nullability information.
-dontwarn javax.annotation.**

# A resource is loaded with a relative path so the package of this class must be preserved.
-keepnames class okhttp3.internal.publicsuffix.PublicSuffixDatabase

# Animal Sniffer compileOnly dependency to ensure APIs are compatible with older versions of Java.
-dontwarn org.codehaus.mojo.animal_sniffer.*

# OkHttp platform used only on JVM and when Conscrypt dependency is available.
-dontwarn okhttp3.internal.platform.ConscryptPlatform
