50/**
51 * Provides access to information about the telephony services on
52 * the device. Applications can use the methods in this class to
53 * determine telephony services and states, as well as to access some
54 * types of subscriber information. Applications can also register
55 * a listener to receive notification of telephony state changes.
56 * <p>
57 * You do not instantiate this class directly; instead, you retrieve
58 * a reference to an instance through
59 * {@link android.content.Context#getSystemService
60 * Context.getSystemService(Context.TELEPHONY_SERVICE)}.
61 * <p>
62 * Note that access to some telephony information is
63 * permission-protected. Your application cannot access the protected
64 * information unless it has the appropriate permissions declared in
65 * its manifest file. Where permissions apply, they are noted in the
66 * the methods through which you access the protected information.
