In Android 4.4 and above you can remove the need for a user gesture so long as the HTML5 Video component lives in your own WebView
webview.setWebChromeClient(new WebChromeClient());
webview.getSettings().setMediaPlaybackRequiresUserGesture(false);
To get the video to autoplay, you'd still need to add autoplay to the video element:
<video id='video' controls autoplay>
<source src='http://192.xxx.xxx.xx/XXXXVM01.mp4' type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"' >
</video>
