Subject [jira] [Created] (CB-1702) device.uuid should use HardwareIdentification.GetPackageSpecificToken, not utils.createUUID
Date Wed, 24 Oct 2012 07:50:14 GMT
Matt Baxter-Reynolds created CB-1702:

             Summary: device.uuid should use HardwareIdentification.GetPackageSpecificToken,
not utils.createUUID
                 Key: CB-1702
             Project: Apache Cordova
          Issue Type: Bug
          Components: Windows 8
            Reporter: Matt Baxter-Reynolds
            Assignee: Jesse MacFadyen

The current implementation creates a device ID and puts it in localStorage:

        // deviceId aka uuid
        var deviceId = localStorage.deviceId;
        if(!deviceId) {
            deviceId = utils.createUUID();
            localStorage.deviceId = deviceId;

This should more properly use WinRT's HardwareIdentification class, e.g.

private string GetHardwareId()
var token = HardwareIdentification.GetPackageSpecificToken(null);
var hardwareId = token.Id;
var dataReader = Windows.Storage.Streams.DataReader.FromBuffer(hardwareId);

byte[] bytes = new byte[hardwareId.Length];

return BitConverter.ToString(bytes);

(I appreciate that's C# - I've cribbed it from another project, but this should work in WinJS.)
