Subject [jira] [Commented] (CB-1047) Android UUID can sometimes be undefined (or otherwise not unique) because of limitations in ANDROID_ID
Date Wed, 25 Jul 2012 20:11:33 GMT

    [ https://issues.apache.org/jira/browse/CB-1047?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13422567#comment-13422567
] 

Simon MacDonald commented on CB-1047:
-------------------------------------

I think if we check to see if the ANDROID_ID is '9774d56d682e549c' then we know it is not
unique as that was the screwed up ID. From there I think we should switch to using the IMEI
of the device or some unique ID of our own making.

> There are many documented situations where the following does not really return a unique

> It *might* make sense to offer this as a value completely separate from device.uuid..
there are many reports that some hardware vendors are actually populating ANDROID_ID with
a manufacturer ID (i.e. ANDROID_ID returns a value, but it is not unique between devices of
the same make / model! How deceptive.).
> Perhaps it could be offered as:
> {code:javascript}
> device.install_id
> {code}
> or something so that developers could opt-in to use it? This way it wouldn't break BC
for those who are interested in maintaining device or install ids from previous versions.
Then, you could get a guaranteed unique id by doing:
> {code:javascript}
> var deviceId = ('install_id' in device ? device.install_id : device.uuid);
> {code}
