public abstract void onServiceStateChanged (ServiceState serviceState)
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 Manifest.permission.ACCESS_FINE_LOCATION
