If my understanding is correct, in general you can't because of
security.
Stuff under /data/data/package/... is protected from any code except
the
package itself.

Hi Mike,
Thanks for your reply.

My xhtml file is under assets folder,it is in the app, then why cant i
use it?

and i can use all images saved in assets in the xhtml page.
 but i cant save image at runtime in the assets folder using
file:///android_asset/filename.jpg
I manually save .jpg file under assets and use it in the xhtml file,
it displays an image.
