Pick up the Android version in the browser by Javascript

Question

I\'m building a web app and wanting to disable transitions effects on Android devices under version 3.0.

Is there anyway to pick up the Android version number by Ja

Answer 1

I can't comment because I don't have enough rep... Just wanted to add that I had to change neiker's code to

var match = ua.match(/Android\s([0-9\.]*)/i);

to make it case insensitive because the Galaxy S3 was returning "android" instead of Android in its user agent

Answer 2

function getAndroidVersion(ua) {
    ua = (ua || navigator.userAgent).toLowerCase(); 
    var match = ua.match(/android\s([0-9\.]*)/i);
    return match ? match[1] : undefined;
};

getAndroidVersion(); //"4.2.1"
parseInt(getAndroidVersion(), 10); //4
parseFloat(getAndroidVersion()); //4.2

Answer 3

Motorola's player user agents can have the following:

Linux;Android ; Release/4.1.2

So, I've had to start using the the following regex:

[a|A]ndroid[^\d]*([\d[_|.]]+\d)

Answer 4

1- Windows phone introduced a fake "android" user agent, so this deal with it
2- As @andy pointed out, there are some models with this format: Android/#.##
3- You can use the flag /i for case-insensitive
4- This code gives you back NaN when its not android and the version as a float when it is.
5- If you find more fake android phones you only need to add the string like this: (?:windows phone|fake phone|android...........

alert( parseFloat(navigator.userAgent.match(/.*?(?:windows phone|android\D+([0-9\.]*))|()/i)[1]) );

Answer 5

I made this function and worked very well in Android 2.6.3, 4.2.2., 6.0.1 in different browsers and devices. I think that can be an alternative.

function check_android_version()
{
    var ua = navigator.userAgent; 
    ua = ua.toLowerCase();

    var and_pos = ua.search("android");
    if(and_pos == -1)
        return 0; //not android

    var pv_pos = ua.indexOf(";", and_pos);
    var versao = ua.slice(and_pos+8, pv_pos);

    return versao;
}

This is quite simple, first, search for the word "android". If not found, returns 0 (is not an Android user agent). Then search for the first ';' after the "android" position that marks the end of the version. Once these positions are gotten, the 'slice' insulates the version numbers (that '+8' removes the word "android" of the final result) an then returns.

If someone find any flaw, would be nice to share.

Answer 6

Use below code to get 2 digit version of Android

var ua = navigator.userAgent;
if( ua.indexOf("Android") >= 0 )
{
  var androidversion = parseFloat(ua.slice(ua.indexOf("Android")+8)); 
  if (androidversion < 2.3)
  {
      // do whatever
  }
}

For example

Mozilla/5.0 (Linux; U; Android 2.2.1; fr-ch; A43 Build/FROYO) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1

will return Android Version = 2.2
