Can an emulator have a unique device ID? And can you use that ID?

Question

I am making a web app using HTML5 and PhoneGap, and I am using the uuid as a one-time login instead of the standard username/password combination. Instead of having the client manually type in the uuid, I want to automatically grab the uuid from the device and login using that information. There is a PhoneGap plugin called Device, which allows you to access your device's uuid.

When I try to test the uuid retrieval on Genymotion, my emulator, I get an error. I think the error is because I am using an emulator and not a device.

EDIT: I found the identifiers on Genymotion, but it is not free. I am still wondering whether I can actually use the ID information.

Solution

You can set uuid for a emulator.

You need to start the emulator like this

emulator -avd jbx86 -prop emu.uuid=5ec33f90-a471-11e2-9e96-0800200c9a66

Basically emulator uuID always returns null. They are hard coded. So you can set at startup.

Can you explain that format? I tried it and it didn't know what "jbx86" was.

I didn't try them, I've found them from those above links. There is another way described in the 2nd link, you can try them

Should this solution still work? Doesn't work for me.
