Android Application - error while opening URL that uses WebRTC in WebView

[Shubham Pratap]

I am working on developing an Android application, in which I want to open a URL in WebView. Now, if I open a simple URL in WebView (like www.google.com) is works just fine. But I want to open a URL which uses WebRTC (Web Real-Time Communication) which errs stating: "Looks like you are using unsupported browser version". I searched on google.com and found that WebRTC starts supporting from Android 5.0 (API level 21) and higher.

My version of Webview is:

using webView.getSettings().getUserAgentString() i get my webview details.

Mozilla/5.0 (Linux; Android 9; Android SDK built for x86 Build/PSR1.180720.075; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/69.0.3497.100 Mobile Safari/537.36
