Android Question Android ID

[khwarizmi]

Hi all
Is the android_id fixed or does it change after reinstalling the system?

Dim phone As Phone
Dim a as string = phone.GetSettings ("android_id")

thanks

Looks like it changes even more:
install 2 different apps on the same phone and you’ll get 2 different IDs
remove and reinstall the same app, and it will get a different ID.
it is unique for each install, not for each device

Therefore, it cannot be relied upon to obtain a unique device identifier.
Is GetAndroidSerial a suitable option for device identification?

Dim uid As cl_dgUID
        uid.Initialize
        Dim d As String=uid.GetAndroidSerial

dgUID - unique ID for your device

Hi all, sooner or later everyone reaches the point where a "reliable" way to get a unique ID to identify a device or a user is much needed. I read almost all the forum's threads about the subject and did some research too, but I couldn't find a definitive word on it or an always good solution...

I think this is relevant to your question:

Android 10 - None of the device unique ids are exposed.

According to this post by Erel (https://www.b4x.com/android/forum/threads/android-jar-targetsdkversion-minsdkversion.87610/#content) On Android 10 " None of the device unique ids are exposed. The only id available is the advertising id: https://www.b4x.com/android/forum/threads/101050/#content"...

If the user chooses the option to stop ads, the Advertising id will not be displayed, and will appear as zeros. Can I force the user to cancel this option, and will this pose a problem when uploading the application to Google Play?
