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