如何获得唯一的 Android 设备 ID？

Question

According to the policy, we must use this method to register the user

Therefore, using email or number to register a user is not a good way for us

According to my studies, there are several ways to get a unique ID

But each has its own problems

I need a method that does not require special access from the user

Using Android ID is a good method. The problem is that it can be changed on rooted phones

And this is very bad in terms of security, of course, in Android lower than 8

Is there a specific trick or method to solve this problem?

I also know an application that does not use Android ID or mac WIFI and Pseudo-Unique ID, but does get the information according to the user's device. Is there a way to know what method it uses?

Answer 1

it's simple all you have to do is use the below code. this method will return android id now all you have to do is add checks at your backend.

val id =  Settings.Secure.getString(
          getContext()?.contentResolver,
          Settings.Secure.ANDROID_ID
          )
