From http://developer.android.com/guide/webapps/webview.html#EnablingJavaScript

For example, if you're developing a web application that's designed specifically for the WebView in your Android application, then you can define a custom user agent string with setUserAgentString(), then query the custom user agent in your web page to verify that the client requesting your web page is actually your Android application.

var ua = navigator.userAgent.toLowerCase();
var isAndroid = ua.indexOf("android") > -1; //&& ua.indexOf("mobile");
if(isAndroid) {
  // Do something!
  // Redirect to Android-site?
  window.location = 'http://android.davidwalsh.name';
}

It's not the right answer it also detect browers like Firefox or Chrome as 'android' . This is the only thing that works: https://stackoverflow.com/questions/6783185/detect-inside-android-browser-or-webview – Steven Nov 08 '17 at 13:35

Why not add a secret param that you will set every time you need it?
