Title:How can I access "assets" folder in Imagetargets during operation in the phone?

Hi. I want to make an AR-appication using QCAR SDK.
Basiclly, I will use client-server networking.

Client(phone user) take a current picture and that image will send to web server that I made.
Then, Server will search the correct image and 3D-object. And server send to client files.
These files that client(smart phone) received are [.dat, .xml, .png, .h].

I don't wanna change QCAR sample code as possible as I can.
As a result, client have to be received four files.
These files are ".dat"(having information for trackable image), ".xml"(having information for tackable image name and size),
".png"(image for texture mapping), "[name].h" (having vertex for 3D object)instead of "teapot.h" in Imagetargets folder.

And then Application be re-started.
So, I guess that new target image and another new 3D-object are renewed.

How can I access "assets" folder in Imagetargets during operation?
And How can I make server-client AR application using QCAR SDK as possible as I don't change example codes?
Is it possible am I thinking?

I can't see to solve this problem anywhere.
Thank you for your attention.

That's right, there is no way to replace this data at runtime.

I'm pretty sure those files are accessed from the pre-compiled closed source java classes so there's no way to replace these values at runtime.

Thanks to your reply Kim!
So, Can you tell me where are stored information of trackable?
I mean that the config.xml and qcar-resources.dat files information have to be stored some arrays.

If you tell me where are stored trackables information,
I am going to replace these values by new values(information of image)that I want to track.

This isn't currently possible, the config.xml and qcar-resources.dat files have to be present in the assets folder at compile time. There is no way to replace these files at runtime.
