Hi Tanaporn,
I missed this issue, sorry for the delay. Did you already solve your problem?
I see from logcat that there's some errors related to the missing baseURI, like

{E211} Base URI is null, but there are relative URIs to resolve.: <>

This can be easily solved by specifying a base uri either in 
storage/extSdCard/foaf.rdf or in your code, passing it to the read method of 
your Model:

model.read(in,"http://baseuri.com");

I didn't test it but I think this should solve the problem.
Tell me if you need more advice, then I'll compile and test your application 
and see where the problem lies exactly.
Hope this helps, bye
