QAndroidJniObject, how to give back data

[mrdebug]

I need to give back a list of objects from java.
I can call a java function having back a String without problem for example
QAndroidJniObject jString= QAndroidJniObject::callStaticObjectMethod<jstring>("it/denisgottardello/multimediapet/multimediapettouch/JavaBridge", "FetchData");

but how can I have back a java.util.Vector, or a java.util.List, or an array of objects like this?

public class JavaObject {

  public String Name;

}

I have tryied this but does not work:
QAndroidJniObject MyData= QAndroidJniObject::callStaticObjectMethod("it/denisgottardello/multimediapet/multimediapettouch/JavaBridge", "FetchData", "()Lit/denisgottardello/multimediapet/multimediapettouch/JavaObject;");
