Unique Identifier in Android Q

Android Q has restricted to access for both IMEI and serial no. It is available only for platform and apps with special carrier permission. Also the permission READ_PRIVILEGED_PHONE_STATE is not available for non platform apps.

Existing version(Android P, Android O, Android M) we have used the serial no for uniquely identified the device. Now we have faced the below Exception while tried to access the device identifier.

Android Q has restricted to access for both IMEI and serial no.

Since hardware ids are restricted, you can use an almost reliable software id like ANDROID_ID:

Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ANDROID_ID)

I used almost since it can be changed on a rooted phone, but reliable on non-rooted devices.

Only system apps will have access to hardware IDs. If your app needs to identify unique instances of your app running on different devices, you should use an API such as Firebase InstanceID service but there are similar options available from different providers as well.

It's worth noting that Google discouraged using Hardware ID features even in older Android versions.
