Remarks

Callback invoked when device service state changes on the registered subscription. Note, the registration subscription ID comes from TelephonyManager object which registers TelephonyCallback by TelephonyManager#registerTelephonyCallback(Executor, TelephonyCallback). If this TelephonyManager object was created with TelephonyManager#createForSubscriptionId(int), then the callback applies to the subscription ID. Otherwise, this callback applies to SubscriptionManager#getDefaultSubscriptionId().

The instance of ServiceState passed as an argument here will have various levels of location information stripped from it depending on the location permissions that your app holds. Only apps holding the Manifest.permission#ACCESS_FINE_LOCATION permission will receive all the information in ServiceState, otherwise the cellIdentity will be null if apps only holding the Manifest.permission#ACCESS_COARSE_LOCATION permission. Network operator name in long/short alphanumeric format and numeric id will be null if apps holding neither android.Manifest.permission#ACCESS_FINE_LOCATION
