How is device supposed to know its deviceid

[Jørn Klungsøyr]

Hi,

I’m probably missing something, but I can’t find in the API anything on how the deviceid is set for a particular device.

Best

Jørn

Jorn,

There are no specific requirements for how a deviceid is set. Depending on the platform we generally use one of:

* Device IMEI number (For GSM devices)

* Android Unique Identifier (for android devices with no radio antennas)

* Hardware NIC ID

* v4 uuid recorded on first-startup (for devices which live in a deep sandbox, like j2me)

all of which are unique for the purposes of knowing which device a submission came from.

Just wanted to chime in here and mention what we're using for Group
Complete.

Basically the whole notion of device IDs gets very screwy with Android
because there's very little that can be depended on. To work around
that and to ensure a more-or-less unique ID we use a UUID created from
the combination of the telephony device ID, telephony SIM serial number
and Android ID.

This gives us a fingerprint that looks like something like
00000000-1039-bc6c-ffff-ffff99d603a9

It's fugly but it works and is better than relying on just one piece of
information that might not be supplied, unique or reliable.

Cheers,

Matt
