Thanks SOB for that code.
I works when I put my all html, css and images files into assets
folder and try to load with webView.loadUrl("file:///android_asset/
Google.html") . All css and images loaded completely.
However similarly when I tried putting all my files into sdcard. It
does not work at all.
Just few more Ques:-
1- Can I save HTML/CSS/Images into that assets folder dynamically at
run time. [As far as I know that assets folder deas not have any
phusicall existence in the Android FileSystem ]
2- If not above point, then How that behavoir can be simulated for
sdcard/or any other physical directory.
Anyways Thanks for all your help
