I needed to send an identifier to our server to identify
users as they use my application. I first used the phone
number, but found that tablets without service had none. So failing
getting a phone number, I did this:
android_id = Secure.getString(this.getContentResolver(), Secure.ANDROID_ID);
But it seems now, that a handful of users, notably those using T-mobile,
have phones that will not yield the above ID.
So I was wondering whether there was some other unique identifier
I could use, or failing that, would like to here suggestions on
generating an identifier that would (almost?) never be a duplicate.
I was thinking of using the time to the millisecond that the app was first
run, plus some random digits. Still, I thought that there might be a more
standard
practice or library for this.
Thanks!
