How do I get information about a phone's IMEI in Android 10?

问题

Before Android 10, I was using the TelephonyManager API to retrieve that info, but it's no longer working in Android 10.

From the Android Developers Documentation Website

Starting in Android 10, apps must have the READ_PRIVILEGED_PHONE_STATE privileged permission in order to access the device's non-resettable identifiers, which include both IMEI and serial number.

Third-party apps installed from the Google Play Store cannot declare privileged permissions.

If your app doesn't have the permission and you try asking for information about non-resettable identifiers anyway, the platform's response varies based on target SDK version:

• If your app targets Android 10 or higher, a SecurityException occurs.
• If your app targets Android 9 (API level 28) or lower, the method returns null or placeholder data if the app has the READ_PHONE_STATE permission. Otherwise, a SecurityException occurs.

If you try to access it, it throws the below exception: java.lang.SecurityException: getImeiForSlot: The user 10180 does not meet the requirements to access device identifiers.
