Unique device ID

[Sarah]

Excuse me if I write this again but I don't want have problem in next
months!

Considering that apple will consider deprecated device unique id

and considering and Easy APNS uses device unique id for identify
device and send message .... we'll have problems when we'll not have
this device unique id?

Thanks

[John Jones]

just create your own id in the app, and transition away from using the uuid.

Apple actually use the device token which is different to the uuid, you do not need to use the uuid at all (I have not been using that for over a year.)

Thanks for you reply! Do you mean that mean that Easy APNS saves uid
in apns tables but it isn't used??
Only device token is used by APNS?? So I could delete this column from
apns tables and all can work without this info?

Thanks!

[John Jones]

Hi

I dont use the apns any more, I wrote my own system (for working with drupal)

But if you swap the uid to be a auto increment number I can not see why that would not work, APNS needs the message to be sent to a device token, it does not care about the uid, this is only if you want to identify the actual device that you are sending messages to, say if you are targeting specific devices, but there are other ways to do this yourself (create a id for the device within your application, and use that if you need to identify devices in your system.) if you are using them to update the settings (receive push notifications etc, then I would use the device token, as this is specific for device and app.)

Thanks for your kindly reply! So with device token I can do
all ...without using guid! Greeeat!

I'm also tring to generate an app uid for identify each user/device
locally but I've not yet found a solution for have an uid that can be
generated with same value also when user cancell and re-install app! I
need that each single device can be identified with a specific uid...
and make this working on Android and iPhone (using Phone gap)

[John Jones]

Can you get the users to registerer a username against your system, email address etc, this would be unique? And could be easilly shared between android and ios

[Sarah]

Yeahhh but I'd like a solution without user registration... as for uid
that I had in iOS... without this deprecated feature all should be OK!
But now I've to find another way for generated an universal uid
working on iOS and Android over Phone Gap

[Sarah]

Please can you help me to resolve this problem?? I'd like to find
right way!!!!

Thanks

[John Jones]

there are algorithms for creating uuid's and if you want them to be unique per device and persistent then create on device, and store, another option is when they register, send back a unique identifier then.

[Dandy]

Thanks for your reply but I don't know what do you mean :(

[John Jones]

To create a uuid in objective C use something like this

+ (NSString*) stringWithUUID {
   CFUUIDRef uuidObj = CFUUIDCreate(nil);//create a new UUID
   //get the string representation of the UUID
   NSString *uuidString = (NSString*)CFUUIDCreateString(nil, uuidObj);
   CFRelease(uuidObj);
   return [uuidString autorelease];
}

Then store this as a property in the app, and you have your ownUUID for the app on that device, there are similar functions for Java.

Thanks for your reply and for help me!!

Do you confirm that with your solution I'll not have problems if Apple
will delete uid feature??
I mean: with your solution I'll not use Apple solution and I'll have
same uid generated if I delete and re-install app?

Thanks

[Sarah]

So!! Isn't there a solution for resolve my problem? (keep uid also
when I delete and re-install app)

Thanks

[John Jones]

There is some persistant storage you can possibly use, but dont know if thats allowed.

They should get the same devicetoken if they delete and reinstall the app, you can test this on your device, by uninstalling, then reinstalling and seeing if its the same devicetoken.

The privacy mob disliked the whole idea of a device id or any way to uniquely identify a device and Apple appears to have conceded the point.

Accordingly, Apple has gone through some significant effort precisely to defeat what you are trying to accomplish here. Device token is subject to (and does) change. Device uid is deprecated. Use of persistent storage outside of sandbox space cleared when the app is installed is expressly verboten.

You have two options of unique identification in apple world. The first is checking the receipt of an in-app purchase when a user expressly restores it (in which case you get a unique hash). The second is requiring the user to login. The days of magical persistent unique identification with no user interaction on iOS are gone.

[John Jones]

Thanks for clearing that up, knew they were heading in that direction, and all the apps that I have done so far have login, or some subscription so I can identify users across devices, os's and even websites when they use the login etc.

[Dandy]

Thanks for your detailed reply!!

What about this solution:   

The first is checking the receipt of an in-app purchase

??

Thanks

for security reasons I prefer not to have in mySQL any UDID, or device
name.
specifically because I don't really need it to generate the PUSH
message (just need the token)

Since Token is unique, if I will copy it to the device UDID (so both
UDID and token will be token)
should it still work ?

for device name I just copy the device language (more important for
future send push in native language)

Since I want to upload my first version with EasyAPN this week ,
I will be happy if someone can help me with this answer soon.

[Bagusflyer]

I think you can use the token id which should be unique for different device.

[John Jones]

That will work fine, or just make the device id not a required field, and dont pass it along with the other parameters when registering the devices.

Some of my systems pass only the token, and if they want to recieve alerts etc.

[Dandy]

But I'd like a solution for Android and iPhone both devices! device token is ok for APNS .... because of returned from apple..... I need a way for have a uid working also on Android

Thanks

[John Jones]

To do that you need to have customers register to tie them in, or just give you an email address, you do not need to store the email address (store a hash (md5) of it if you dont want email addresses in the db.

The previous answer was for somebody that did not want the devicename or udid in the db.

Can you share your code for Drupal?

[John Jones]

Hi

It will be hopefully a contrib module within a couple of weeks, a couple of little issues i want to sort first.
