title: Twitter video not rendering in webview
body: <p>I get <code>tweet blockquote</code> in the description . I create a <code>html</code> document and appened <code>blockquote</code> and <code>twitter script</code> and load that <code>html</code> to  <code>webview</code>. All the tweets and videos renders properly. Only problem is, When i click on the video, it shows a black screen. This happening for all twitter videos in <code>kitkat</code> devcies. Works fine in lollypop and above. I know there is a bug in API level 16 and 17 and videos won't play in the webview. But from API level 18, videos in webview must play and all other videos are playing in the webview in these devices. Only the twitter videos are not working. Below is my html content:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt; &lt;head&gt; 
  
  &lt;script async src ="http://platform.twitter.com/widgets.js" 
  charset="utf-8"&gt;&lt;/script&gt;&lt;/head&gt; &lt;body&gt;&lt;blockquote class="twitter-tweet" data-lang="en"&gt;&lt;p lang="en" dir="ltr"&gt;Goodbye &lt;a href="https://twitter.com/hashtag/Sarbjit?src=hash"&gt;#Sarbjit&lt;/a&gt;.Gratitude to &lt;a href="https://twitter.com/OmungKumar"&gt;@OmungKumar&lt;/a&gt; &lt;a href="https://twitter.com/Vanita_ok"&gt;@Vanita_ok&lt;/a&gt; &lt;a href="https://twitter.com/SandeepSinghOne"&gt;@SandeepSinghOne&lt;/a&gt; &lt;a href="https://twitter.com/RichaChadda_"&gt;@RichaChadda_&lt;/a&gt; &lt;a href="https://twitter.com/kirandeohans"&gt;@kirandeohans&lt;/a&gt; &lt;a href="https://twitter.com/hashtag/AishwaryaRai?src=hash"&gt;#AishwaryaRai&lt;/a&gt; CREW &lt;a href="https://t.co/1tC4CiCwBN" target="_blank"&gt;pic.twitter.com/1tC4CiCwBN&lt;/a&gt;&lt;/p&gt;&amp;mdash; Randeep Hooda (@RandeepHooda) &lt;a href="https://twitter.com/RandeepHooda/status/709620030510600192"&gt;March 15, 2016&lt;/a&gt;&lt;/blockquote&gt;&lt;/body&gt; &lt;/html&gt;
  </code></pre>
  
  <p>This is my webview code:</p>
  
  <pre><code>public static void setupWebview(WebView webView) {
      webView.getSettings().setJavaScriptEnabled(true);
      webView.getSettings().setDomStorageEnabled(true);
      if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.LOLLIPOP) {
          webView.getSettings().setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);
      }
      webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
  
      webView.getSettings().setPluginState(WebSettings.PluginState.ON);
      webView.setBackgroundColor(Color.parseColor("#ffffff"));
      android.webkit.CookieManager.getInstance().setAcceptCookie(true);
  }
  </code></pre>
  
  <p>What might be the issue here. I googled a lot, but couldn't get any solution. Is anyone else also, facing similar issue?</p>
  
  <p>Thanks in Advance</p>
