title: When I try to get whole page screenshot it returns a white screen?
body: <p><strong>I'm trying to get the whole screen shot programmatically in webview. When I test my code, it returns a white screen.</strong></p>
  
  <p>I've tried different codes, but I couldn't get it done. Sometimes it returns a white screen, sometimes it returns a black screen. I've also added my manifest Internet permission and wrote an external storage permission. My xml file exist only in webview. </p>
  
  <p>I've also tried "sleep" for five seconds but it didn't work.</p>
  
  <pre><code>public static Bitmap loadBitmapFromView(WebView v, int width, int height) 
  {
      Bitmap b = Bitmap.createBitmap(width , height, Bitmap.Config.ARGB_8888);                
      Canvas c = new Canvas(b);
      v.layout(0, 0, v.getLayoutParams().width, v.getLayoutParams().height);
      v.draw(c);  
      FileOutputStream fos = null;
      try 
      {
          fos = new FileOutputStream("/sdcard/image.jpg" );
      } 
      catch (FileNotFoundException e1) 
      {
          // TODO Auto-generated catch block
          e1.printStackTrace();
      }
      b.compress(Bitmap.CompressFormat.JPEG, 90, fos);
  
      try 
      {
          fos.close();
      } 
      catch (IOException e) 
      {
          // TODO Auto-generated catch block
          e.printStackTrace();
      }
      return b;
  }

  <p>I call this method in <code>onpageFinished()</code>. By <code>loadBitmapFromView(webView, webView.getWidth(), webView.getHeight());</code> I ensure loading the whole page. In my opinion, it tries to get a screen shot when webview doesn't load before the call. But I call it in the <code>onpageFinished()</code> method. It runs when webview loads completely.</p>
