NoClassDefFoundError on release build

I'm using Dagger for DI in my app, and a few users are experiencing an issue where they download the app from the PlayStore and my app immediately crashes.

The stacktrace is as follows:

My proguard rules:

Remove logs

-assumenosideeffects class android.util.Log {
public static boolean isLoggable(java.lang.String, int);
public static int v(...);
public static int i(...);
public static int w(...);
public static int d(...);
public static int e(...);
}

http://stackoverflow.com/questions/29679177/cardview-shadow-not-appearing-in-lollipop-after-obfuscate-with-proguard/29698051

-keep class android.support.v7.widget.RoundRectDrawable { *; }

OkHttp

-keepattributes Signature
-keepattributes Annotation
-keep class okhttp3.** { ; }
-keep interface okhttp3.* { ; }
-dontwarn okhttp3.*

Realm

-keep class org.unos.ett.app.data.entity** { ; }
-keep class io.realm.annotations.RealmModule
-keep @io.realm.annotations.RealmModule class *
-keep class io.realm.internal.Keep
-keep @io.realm.internal.Keep class *
-dontwarn javax.*
-dontwarn io.realm.**

GSON 2.2.4 specific rules

Gson uses generic type information stored in a class file when working with fields. Proguard

removes such information by default, so configure it to keep all of it.

-keepattributes Signature

For using GSON @expose annotation

-keepattributes Annotation

-keepattributes EnclosingMethod

Gson specific classes

-keep class sun.misc.Unsafe { ; }
-keep class com.google.gson.stream.* { *; }

Retrofit 2.X

https://square.github.io/retrofit/

-dontwarn retrofit2.**
-keep class retrofit2.** { *; }
-keepattributes Signature
-keepattributes Exceptions

-keepclasseswithmembers class * {
@retrofit2.http.* ;
}

AppCompatv7

-keep public class android.support.v7.widget.** { ; }
-keep public class android.support.v7.internal.widget.* { ; }
-keep public class android.support.v7.internal.view.menu.* { *; }

-keep public class * extends android.support.v4.view.ActionProvider {
public (android.content.Context);
}

http://stackoverflow.com/questions/29679177/cardview-shadow-not-appearing-in-lollipop-after-obfuscate-with-proguard/29698051

-keep class android.support.v7.widget.RoundRectDrawable { *; }

Okio

-keep class sun.misc.Unsafe { ; }
-dontwarn java.nio.file.
-dontwarn org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement
-dontwarn okio.**

Note that this only happens for a certain set of my users, on Samsung's TabS using KitKat.

Is any further information needed?

This appears to be a question - please use StackOverflow with the dagger-2 tag instead, as that is a better forum for questions.

This isn't a question, this is a bug with Dagger 2.

Nope, it's an issue with either your build system or an OEM has done something with your apk that is funky. If it were a dagger error, the code wouldn't compile.
