Fixing issue with screenshot icon being stretched.

        int previewWidth = data.previewWidth;

        int previewHeight = data.previewheight;

        final int shortSide = mImageWidth < mImageHeight ? mImageWidth : mImageHeight;

        Bitmap preview = Bitmap.createBitmap(previewWidth, previewHeight, data.image.getConfig());

        Canvas c = new Canvas(preview);

        Canvas c = new Canvas();

        Paint paint = new Paint();

        ColorMatrix desat = new ColorMatrix();

        desat.setSaturation(0.25f);

        paint.setColorFilter(new ColorMatrixColorFilter(desat));

        Matrix matrix = new Matrix();

        matrix.postTranslate((previewWidth - mImageWidth) / 2,

                            (previewHeight - mImageHeight) / 2);

        int overlayColor = 0x40FFFFFF;

        Bitmap picture = Bitmap.createBitmap(previewWidth, previewHeight, data.image.getConfig());

        matrix.setTranslate((previewWidth - mImageWidth) / 2, (previewHeight - mImageHeight) / 2);

        c.setBitmap(picture);

        c.drawBitmap(data.image, matrix, paint);

        c.drawColor(0x40FFFFFF);

        c.drawColor(overlayColor);

        c.setBitmap(null);

        Bitmap croppedIcon = Bitmap.createScaledBitmap(preview, iconSize, iconSize, true);

        // Note, we can't use the preview for the small icon, since it is non-square

        float scale = (float) iconSize / Math.min(mImageWidth, mImageHeight);

        Bitmap icon = Bitmap.createBitmap(iconSize, iconSize, data.image.getConfig());

        matrix.setScale(scale, scale);

        matrix.postTranslate((iconSize - (scale * mImageWidth)) / 2,

            .bigPicture(picture);

        mNotificationBuilder.setStyle(mNotificationStyle);

        // For "public" situations we want to show all the same info but

        // On the tablet, the large icon makes the notification appear as if it is clickable (and

        // on small devices, the large icon is not shown) so defer showing the large icon until

        // we compose the final post-save notification below.

        mNotificationBuilder.setLargeIcon(croppedIcon);

        mNotificationBuilder.setLargeIcon(icon);

        // But we still don't set it for the expanded view, allowing the smallIcon to show here.

        mNotificationStyle.bigLargeIcon((Bitmap) null);
