private class customwebviewclient extends webviewclient {      @override     public boolean shouldoverrideurlloading(webview view, string url) {         view.loadurl(url);         return true;     }      @override     public void onreceivedsslerror(webview view, sslerrorhandler handler, sslerror error) {         log.d(tag, "ignoring ssl certificate error...");         handler.proceed();     } } 

i tested app on phones running lollipop. guess related webview. help?

the officially supported way of working webrtc using webrtc-capable browsers (i.e. chrome, firefox , opera, , android browser). webview indeed support webrtc (though not everything), how webrtc working in webview better answered webview users.

on other hand, doing some research seems crosswalk better option, embeds functional chrome browser.
