The Ghostly Glare of Doom: Ionic 2 Strikes on Android

While my application runs smoothly in the browser, I encounter an error when trying to run it on my device. The issue is as follows:

 0     758771   log      deviceready has not fired after 5 seconds.
 1     758797   log      Channel not fired: onDOMContentLoaded
 2     758932   error    Uncaught TypeError: Cannot read property '6' of undefined, http://(ip address)/build/js/Reflect.js, Line: 894

The problematic code resides within Reflect.js, however, being a part of Ionic's packaging, I am unable to modify it which leaves me unsure how to resolve this issue.

function CreateUUID() {
    var data = GenRandomBytes(UUID_SIZE);
    // mark as random - RFC 4122 § 4.4
    data[6] = data[6] & 0x4f | 0x40;
    data[8] = data[8] & 0xbf | 0x80;
    var result = "";
    for (var offset = 0; offset < UUID_SIZE; ++offset) {
        var byte = data[offset];
        if (offset === 4 || offset === 6 || offset === 8)
            result += "-";
            if (byte < 16)
                result += "0";
            result += byte.toString(16).toLowerCase();
        }
    return result;
}

It appears that the function GenRandomBytes() is returning null in this scenario. Any assistance would be greatly appreciated.

There are times when errors in Android Studio's logcat can be overlooked. The key may lie in uncovering the actual issue using Chrome's web tools.

Troubleshooting Android through Chrome can be a bit tricky, check out: Chrome's remote debugging (USB debugging) not working for Samsung Galaxy S3 running android 4.3

Specifically:

I was developing for android using Android Studio. So I had almost everything installed but Chrome didn't show me the list of devices. The solution was to find adb.exe which was already on my PC, and to run adb.exe devices. That did the trick for me. – Saeed Neamati

Once you have your app inspected and viewable in web tools, I suggest hitting Ctrl+R to refresh and check for any Javascript/HTML/CSS errors captured during page load.
