Use cases:
1 AndroidJavaObject needs to be passed to multiple independent bodies of code -- each which have their own independent duration for holding onto the AndroidJavaObject.

One returns an AndroidJavaObject from an AndroidJavaProxy method then AndroidJavaProxy automatically calls Dispose() on that AndroidJavaObject outside the developer's visibility or control while other code may need to continue using that AndroidJavaObject.

Workaround script:
public static AndroidJavaObject NewAndroidJavaObject(AndroidJavaObject androidJavaObject)
{
if (androidJavaObject == null)
{
return null;
}
AndroidJavaClass objectsClass = AndroidUtilities.objectsClass;
if (objectsClass == null)
{
AndroidUtilities.objectsClass = objectsClass = new AndroidJavaClass("java.util.Objects");
}
return objectsClass.CallStatic<AndroidJavaObject>("requireNonNull", androidJavaObject);
}
