$mdUtil: now is not a function

[poltorak]

I got error on my project: Property 'now' of object # is not a function

I found out that it happens only on devices with Android 4.0 - 4.2. I also found out that it happens here.

Problem is that I can't reproduce it. I can't tell more details because that error occurs only on production where all js files are uglified.

Can someone help or has the same problem?

EDIT:
Method now from $mdUtil looks like:

now: window.performance ?
      angular.bind(window.performance, window.performance.now) :
      Date.now,

and on caniuse.com I found that neither window.performance.now and Date.now are not supported in Android 4.1 - 4.3

EDIT 2:
Simple solution is to check if window.performance and Date.now is available for example

if (window.performance) {
    angular.bind(window.performance, window.performance.now);
    } else if (Date.now) {
        Date.now;
    } else {
        function() {
            return new Date().getTime();
        };
    }

It still happens to me, even with the fix in 53c1f09 , i.e., the code is:

now: window.performance ?
      angular.bind(window.performance, window.performance.now) : Date.now || function() {
      return new Date().getTime();
    }

Error I get:

TypeError: Property 'now' of object #<Object> is not a function

The bug is that window.performance on some systems (android 4.2) doesn't have .now method (but window.performance object does exist).

The solution is to add "&& window.performance.now" like this:

now: window.performance && window.performance.now ?
      angular.bind(window.performance, window.performance.now) : Date.now || function() {
      return new Date().getTime();
    }

If you want to reproduce it, the issue still happens in this system:

{

  "appCodeName": "Mozilla",
  "appVersion": "5.0 (Linux; U; Android 4.2.2; vi-vn; XoLo A500S Build/JDQ39) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30",
  "platform": "Linux armv7l",

}
