After configuring the app everything is working fine but sometimes asking for google reCaptacha.
The solution: First of all turnoff desktop mode update rocket_web.io file and check again.
In case of not resolved, now from your HTML file, you can run the Bridge Class as a Javascript function (Use version 1.3.5 or above):
<div class="g-recaptcha" data-sitekey="YOUR_CAPTCHA_SITE_KEY" data-callback="captchaResponse"></div>
<script type="text/javascript">
function captchaResponse(token){
BridgeWebViewClass.reCaptchaCallbackInAndroid(token);
}
</script>
