Did you added the ProGuard rules for this library?

ProGuard

-keep class com.google.android.gms.maps.** { *; }
-keep interface com.google.android.gms.maps.* { *; }

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

-keepclasseswithmembers class * {
    @retrofit2.http.* <methods>;
}

For anyone who had stumbled across this issue, may have to add the below rule as well along with the mentioned proguard rules. -keep class com.akexorcist.googledirection.model.* { ;}
