So, this is an edge case that no amount of Googling seems to unearth.

I have an enum in Kotlin;

package myapp
public enum State {
    STATE_SUCCEEDED,
    STATE_FROZEN,
    STATE_WAITING,
    STATE_IN_PROGRESS,
    STATE_FAILED
}

I then have an object that contains this enum as a value in a member variable

package myapp
class AppState (
    val state: State
)

Then, in C, I want to create an instance of AppState

jclass cls = (*env)->FindClass(env, AppState_ClassPath);
if (cls == NULL) {
    __android_log_print(ANDROID_LOG_INFO, "DEBUG", "AppState class is null");
}
jmethodID mid = (*env)->GetMethodID(env, cls, "<init>", "(Lmyapp/State;)V");
return (*env)->NewObject(
    env, 
    cls, 
    mid, 
    enumState
);

Now, when the C code is called from Kotlin, I get the error

JNI DETECTED ERROR IN APPLICATION: JNI NewStringUTF called with pending exception java.lang.NoSuchMethodError: no non-static method "Lmyapp/AppState;.<init>(Lmyapp/State;)V"

I understand why I get this error, since Enums have no public constructor, but not sure of the workaround. How should this enum be added to the signature?

Many thanks!
