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