Unique id working on iPhone and Android

[sarah_77]

Hi! I've read that in next version of iOS will not disponible GUID for identify device.

I'm creating a PhoneGap for Android and iPhone using Sencha Touch 2.0 and I'd like to find a solution for generate and unique ID that allows to identify device and for know (recalculate) same GUID also after delete and re-install of my app.

If GUID calculate is 12345678

must be same also if I delete app and on same device I install it another time

We do have a new class, Ext.data.UuidGenerator that you can use but does PhoneGap give you anything that is unique to the device? WebKit doesn't but since PhoneGap gives you more access it may.

Thanks for your reply!

I don't know this:

Ext.data.UuidGenerator

Can I use this solution in my project?? (PhoneGap + SenchaTouch 2.0 on iPhone and Android)?? Or not??

but does PhoneGap give you anything that is unique to the device?

Can't I use this: Ext.data.UuidGenerator??


Thanks

Ext.data.UuidGenerator has been apart of ST2 since PR1. The problem is that there isn't anything unique to the device, if you uninstall an app, how will you be able to reliably create the exact same id? You can save to local storage but what happens when someone clears local storage?

It this, I don't need Ext.data.UuidGenerator

What about a GUID generated using MAC??

But nobody of you have this need??? Identify (always) a device for logs/feedback/lastupdate info.... etc??

Why lose all info about device if use delete (and re-install) app?

Thanks

Can you get it using phonegap?

Can you get it using phonegap?

I don't know this

I'd like to find a solution that works on Android and iPhone (using PhoneGap or Sencha Touch)

I'm sure there are ways to do this, but it is a PhoneGap issue, not a Sencha issue.

[sarah_77]

So right way is use PG??

And what do you think to create ad info on localstore with MAC_GUIDGeneratedLocally

using Sencha Touch

and keep saved this info also when app is deleted?? (Android and iPhone)


I'm also searching righr solution

Using the MAC to create an id would be good as the MAC should be unique to every device. I would some means of encrypting it as you don't just want to use the MAC address in plain text. You should save it to local storage so that the client knows about it. At app startup, get that id from local storage and use it, if it doesn't exist, then that's when you would generate a new one.
