Package Summary

The android.telephony package contains the following packages:

Callback methods that notify an application about changes to phone numbers themselves. When used with a TextView object, it formats the text as a phone number using methods in the PhoneNumberUtils class. PhoneNumberUtils

A utility class that contains methods for processing strings containing phone numbers.

PhoneStateListener

Callback methods that track changes in the state of the mobile network connection, the call, or other telephony objects. ServiceState

Methods that return information about the current mobile network service provider and the availability of service.

TelephonyManager

Because these classes don't control hardware or change state information about phone calls, they don't have any access control.
