title: Pause WebView video instead of whole WebView
body: <p>I have a <code>WebView</code> with youtube video and 3 tabs. YouTube video is available in 1st Tab while in other 2 tabs there is a content.</p>
  
  <p>Now i want to pause a video when user moves to other tabs. I have tried with </p>
  
  <pre><code>webView.onPause();
  </code></pre>
  
  <p>and</p>
  
  <pre><code>Class.forName("android.webkit.WebView")
                                  .getMethod("onPause", (Class[]) null)
                                  .invoke(webView, (Object[]) null);
  </code></pre>
  
  <p>but it is pausing whole <code>WebView</code> and my other 2 tabs are also not responding. How to stop just a video instead of whole <code>WebView</code> process</p>
