Question

I am using Java native function -

In C++ my native function -

You would have to create a wrapper for the ArrayList in C++. Something like:

vector  vec;

jclass clazz = (*env).FindClass("java/util/ArrayList");
jobject obj = (*env).NewObject(clazz, (*env).GetMethodID(clazz, "", "()V"));

for (int n=0;n(vec[n]);

   jstring _str = (*env).NewStringUTF(str);

   (*env).CallVoidMethod(object, (*env).GetMethodID(clazz, "add", "(java/lang/Object)V"), _str);

}

return obj;
