javascript - How to detect only the native Android browser

Question

it's easy to detect the Android device, but I am having trouble detecting ONLY the Android native browser. Problem is the Dolphin browser has an almost identical user-agent string, and I'd like a way to know if they are using the native browser or not..

Is this possible?

Answer 1

you simply need to test a few parts of the user agent string in order to make sure you have the default android browser:

var nua = navigator.userAgent;
var is_android = (nua.indexOf('Mozilla/5.0') > -1 && nua.indexOf('Android ') > -1 && nua.indexOf('AppleWebKit') > -1);

you can use the following to ensure that you do not match chrome within android, although on a lot of devices now, chrome is being used as the default browser.

var nua = navigator.userAgent;
var is_android = ((nua.indexOf('Mozilla/5.0') > -1 && nua.indexOf('Android ') > -1 && nua.indexOf('AppleWebKit') > -1) && !(nua.indexOf('Chrome') > -1));

EDIT: If you want to protect against case sensitivity, you can use the following:

var nua = navigator.userAgent.toLowerCase();
var is_android = ((nua.indexOf('mozilla/5.0') > -1 && nua.indexOf('android ') > -1 && nua.indexOf('applewebkit') > -1) && !(nua.indexOf('chrome') > -1));
