Android 12 应用程序可以访问设备的哪些唯一硬件身份信息

Question

I'm wondering what information applications can obtain regarding the hardware ID. Which device-specific credentials such as Mac Address, Bluetooth Mac Address, IMEI are accessible to user applications.

Answer 1

You can find detailed info regarding identifiers in the article: https://developer.android.com/training/articles/user-data-ids

Just pay attention to changes in Android 10:

Android 10 (API level 29) adds restrictions for non-resettable identifiers, which include both IMEI and serial number. Your app must be a device or profile owner app, have special carrier permissions, or have the READ_PRIVILEGED_PHONE_STATE privileged permission in order to access these identifiers.
