Detect whether a website runs in Chrome browser or webView of an Chrome app

[Dave L]

Hi, 

Does anyone know how to detect whether a website runs in Chrome browser or webview of an Chrome packaged app ?

The navigator.userAgent won't tell the difference.

Thanks

I am not sure it should. I am not sure you should be able to detect that.

You can use crbug.com for feature requests (look for an existing one first).

The useragent does, in fact, have a difference; WebView includes "; wv" in the platform token, as explained here: https://developer.chrome.com/multidevice/user-agent

​Dave is referring to the <webview> element, used by Chrome applications. I do not think it applies.​

Thanks for your info.

I resolved my issue by appending kind of "webview-id" into useragent string on loading webview.

window.onload = function () {

     ...

     var userAgent = navigator.userAgent;

     userAgent = "mywebview " + userAgent;

     ...
