Remarks
Callback invoked when device call state changes.
Reports the state of Telephony (mobile) calls on the device for 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().
Note: The state returned here may differ from that returned by TelephonyManager#getCallState(). Receivers of this callback should be aware that calling TelephonyManager#getCallState() from within this callback may return a different state than the callback reports.
