user agent - How to detect the stock Android browser

Question

Navigating to http://whatsmyuseragent.com/ shows me my stock Android browser on my Galaxy Nexus running 4.2.1 has the user agent

Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/534.24 (KHTML, like Gecko) Chrome/11.0.696.34 Safari/534.24

There is nothing in this user agent that allows me to uniquely detect that it is a stock Android browser. The Chrome for Android app at least has android in the UA. Is there any way for me to detect the stock Android app?

Answer 1

var navU = navigator.userAgent;

// Android Mobile
var isAndroidMobile = navU.indexOf('Android') > -1 && navU.indexOf('Mozilla/5.0') > -1 && navU.indexOf('AppleWebKit') > -1;

// Apple webkit
var regExAppleWebKit = new RegExp(/AppleWebKit/([d.]+)/);
var resultAppleWebKitRegEx = regExAppleWebKit.exec(navU);
var appleWebKitVersion = (resultAppleWebKitRegEx === null ? null : parseFloat(regExAppleWebKit.exec(navU)[1]));

// Chrome
var regExChrome = new RegExp(/Chrome/([d.]+)/);
var resultChromeRegEx = regExChrome.exec(navU);
var chromeVersion = (resultChromeRegEx === null ? null : parseFloat(regExChrome.exec(navU)[1]));

// Native Android Browser
var isAndroidBrowser = isAndroidMobile && (appleWebKitVersion !== null && appleWebKitVersion < 537) || (chromeVersion !== null && chromeVersion < 37);
