Hi Sean, Thanks for replying.
I got the idea what exactly you want to say. The code does not work straight forward. It is crashing at drawing canvas from webview. w.draw(tempCanvas); If I comment this line it it saves yahoo.jpg file totally black in color. nothing comes out there. Let me try what is can be done to get the actual view of any site. Anyway thanks.
