Remarks
A callback class for monitoring changes in specific telephony states on the device, including service state, signal strength, message waiting indicator (voicemail), and others.
To register a callback, use a TelephonyCallback which implements interfaces regarding EVENT_*. For example, FakeServiceStateCallback extends TelephonyCallback implements TelephonyCallback.ServiceStateListener.
Then override the methods for the state that you wish to receive updates for, and pass the executor and your TelephonyCallback object to TelephonyManager#registerTelephonyCallback. Methods are called when the state changes, as well as once on initial registration.
Note that access to some telephony information is permission-protected. Your application won't receive updates for protected information unless it has the appropriate permissions declared in its manifest file. Where permissions apply, they are noted in the appropriate sub-interfaces.
