Android: take screenshot of whole WebView in Nougat ( Android 7 )

Question

I use below code to take screenshot from a WebView. it works well in Android 6 and lower versions but in Android 7 it takes only the visible part of the webview.

// before setContentView
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            WebView.enableSlowWholeDocumentDraw();
        }
...
// before set webview url
webView.setDrawingCacheEnabled(true);
// after html load complete
final Bitmap b = Bitmap.createBitmap(webView.getMeasuredWidth(),
                webView.getContentHeight(), Bitmap.Config.ARGB_8888);
        Canvas bitmapHolder = new Canvas(b);
        webView.draw(bitmapHolder);

but bitmap b is not complete. How can I take screenshot of whole WebView in Android Nougat?

Edit:
I found out the webView.getContentHeight doesn't works well. I hard coded the whole webview height and it works well. So the Question is : How can I get the Whole WebView Content Height in Android Nougat?
