PhoneStateListener

public class PhoneStateListener
extends Object

java.lang.Object
↳	android.telephony.PhoneStateListener

A listener class for monitoring changes in specific telephony states on the device, including service state, signal strength, message waiting indicator (voicemail), and others.

Override the methods for the state that you wish to receive updates for, and pass your PhoneStateListener object, along with bitwise-or of the LISTEN_ flags to TelephonyManager.listen().

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 LISTEN_ flags.
