[Android] Failed resolving constructor for class 'net.gotev.uploadservice.MultipartUploadRequest' with 3 parameters.

This plugin works great on iOS, love it and thank you! However I'm running into an issue on Android:

Error: java.lang.Exception: Failed resolving constructor for class 'net.gotev.uploadservice.MultipartUploadRequest' with 3 parameters. Check the number and type of arguments.
JS: Primitive types need to be manually wrapped in their respective Object wrappers.
JS: If you are creating an instance of an inner class, make sure to always provide reference to the outer `this` as the first argument.

We use proguard in our app with the following specified:

-keep,includedescriptorclasses class net.gotev.uploadservice.**
-keep,includedescriptorclasses public interface net.gotev.uploadservice.**

Our tns info:

│ Component      │ Current version     │ Latest version │ Information    │
│ nativescript     │ 3.3.1        │ 3.3.1          │  Up to date │
│ tns-core-modules │ 3.3.0     │ 3.3.0          │  Up to date │
│ tns-android           │ 3.3.1       │ 3.3.1    │  Up to date │
│ tns-ios                 │ 3.3.0       │ 3.3.0          │ Up to date       │

Curious if anything jumps out we could try or if others have also run into this and some possible solutions?

Turns out this was simply related to Proguard setup. The entries needed to be like this instead:

-keep,includedescriptorclasses public class net.gotev.uploadservice.** { *; }
-keep,includedescriptorclasses public interface net.gotev.uploadservice.** { *; }
-keep,includedescriptorclasses public enum net.gotev.uploadservice.** { *; }
