Sorry Sean,
That was a typo error. The looks like
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
WebView w = new WebView(this);
w.loadUrl("http://www.yahoo.com";);
Bitmap mBitmap = null;
ByteArrayOutputStream mByteArrayOpStream = null;
//get the picture from the webview
Picture picture = w.capturePicture();
//Create the new Canvas
Canvas mCanvas = new Canvas();
//Copy the view canvas to a bitmap
try{
//w.draw(mCanvas);
//mCanvas.save();
//picture.draw(mCanvas);
mCanvas.drawPicture(picture);
//int restoreToCount =mCanvas.save();
//mCanvas.drawPicture(picture);
//mCanvas.restore();
}
catch (Exception e) {
e.printStackTrace();
}
mBitmap = Bitmap.createBitmap(w.getWidth(), w.getHeight
(),Config.ARGB_8888);
mCanvas.drawBitmap(mBitmap, 0, 0, null);
if(mBitmap!= null) {
mByteArrayOpStream = new ByteArrayOutputStream();
mBitmap.compress(Bitmap.CompressFormat.JPEG, 90,
mByteArrayOpStream);
try {
fos = openFileOutput("yahoo.jpg",
MODE_WORLD_WRITEABLE);
fos.write(mByteArrayOpStream.toByteArray());
fos.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Thanks in Advance
AJ
