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