Android Api 19 Initializer Error

If I disable ProGuard/R8’s minification feature the problem only disappear in android versions upper than 19. In api version 19, the problem still occurs. This is my proguard rules for this project: -keep class org.jivesoftware.smack.initializer.VmArgInitializer -keep class org.jivesoftware.** { *;} -keepclassmembers enum * {*;}
