Hi All,
I am facing a problem. I launched a webview with some url. After url
is completely loaded I try to get its content in a Canvas. But I am
unable to do so. its crashing at libsgl.so
My goal is to get webview complete data in a bitmap. There is one api
getDrawingCache() which gets the webview data in a bitmap format, but
it gets only the visible content. I actually want the whole content in
a bitmap.
If there is some another way, then how can I go about that.
Here is mine code.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
WebView w = new WebView(this);
w.loadUrl("http://www.msn.com";);
int w1 = w.getWidth();
int h1 = w.getContentHeight();
Bitmap myBitMap = Bitmap.createBitmap(w1,h1, Bitmap.Config.ARGB_8888);
Canvas myCanvas = new Canvas();
w.draw(myCanvas); //
**********CRASH POINT **********//
savePicture(myBitMap, "yahoo2.jpg");
*********************************************************************************************
// Saving it as a file to locacal filesystem
*********************************************************************************************
private void savePicture(Bitmap bitmap, String filename) {
String fileName = filename;
if(bitmap!= null) {
//BitmapDrawable drawable = new BitmapDrawable(mBitmap);
//getWindow().setFeatureDrawable(Window.FEATURE_LEFT_ICON,
(Drawable)drawable);
ByteArrayOutputStream byteArrayOpStream = new
ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 90,
byteArrayOpStream);
try {
FileOutputStream fos = openFileOutput(fileName,
MODE_WORLD_WRITEABLE);
fos.write(byteArrayOpStream.toByteArray());
/*byte[] picByteArry =
picture.toString().getBytes();
fos.write(picByteArry);*/
fos.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I am also pasting the crash logs which are shown in ddms.
