Android Question GetSubscriberId sometimes returns value and other times nothing.

[vecino]

Hi, something strange is happening to me lately, some tablets return a value when I run phi.GetSubscriberId and other times (the same tablet) return nothing, empty string.
Could it be a tablet failure?
Thank you.

Sub getValor As String
  Dim rp As RuntimePermissions
  rp.CheckAndRequest(rp.PERMISSION_READ_PHONE_STATE)   
  Wait For Activity_PermissionResult (Permission As String,Result As Boolean)
  '
  Dim phi As PhoneId
  Return (phi.GetSubscriberId)                               
End Sub

Forget from these hardware ids. They will not work on new Android devices.

Either use your own random id or use the advertiser id.

Hey, none of these will work now?

What is "use the advertiser id"?
Is there no other value that identifies a device physically?
Thank you.

Do not fear the search engine, it's both helpful and delivers results. First hit:

The advertising ID is a unique, user-resettable ID for advertising, provided by Google Play services.

Well, it's no use to me, I don't use "Google Play".

A random value is also useless because it does not identify a device. Just copy that identifier to another device and it's the same.

That's why I'm asking for a unique "physical" identifier that can't be matched on any other device.

Thank you.

It doesn't? That's strange, that's how I use it, and it's working fine.

Just copy that identifier to another device and it's the same.

You make it sounded very simple to copy the identifier. How would your typical users do that?

Copying the file to another device.
It's simple. I probably didn't understand your question.

How do you hide the generated identifier?
Thank you.

Hi, can you explain how you do it?
Thank you.

Please don't "bump" your threads. I already gave you the complete answer on post #2. There are no accessible hardware ids on new versions of Android.

Sorry, I don't understand what I've done wrong.
How should I remind another user to help me, if they can?
