Well, based on your example code, my suggestion is to do something like this:
WebView w = new WebView(this);
w.loadUrl("http://www.yahoo.com";);
// Copy the view canvas to a bitmap
Canvas tempCanvas = new Canvas();
w.draw(tempCanvas);
Bitmap screenshot = Bitmap.createBitmap(w.getWidth(), w.getHeight(),
Config.ARGB_8888);
tempCanvas.drawBitmap(screenshot, 0, 0, null);
// Save to disk
if(bmpBuffer != null) {
mByteArrayOpStream = new ByteArrayOutputStream();
bmpBuffer.compress(Bitmap.CompressFormat.JPEG, 90,
mByteArrayOpStream);
fos = openFileOutput("yahoo.jpg", MODE_WORLD_WRITEABLE);
fos.write(mByteArrayOpStream.toByteArray());
fos.close();
}
NOTE: I haven't tested this, it's only to describe what I meant.
You'll probably need to tweak the code to make it work properly.
