47/**
48 * Provides access to information about the telephony services on
49 * the device. Applications can use the methods in this class to
50 * determine telephony services and states, as well as to access some
51 * types of subscriber information. Applications can also register
52 * a listener to receive notification of telephony state changes.
53 * <p>
54 * You do not instantiate this class directly; instead, you retrieve
55 * a reference to an instance through
56 * {@link android.content.Context#getSystemService
57 * Context.getSystemService(Context.TELEPHONY_SERVICE)}.
58 * <p>
59 * Note that access to some telephony information is
60 * permission-protected. Your application cannot access the protected
61 * information unless it has the appropriate permissions declared in
62 * its manifest file. Where permissions apply, they are noted in the
63 * the methods through which you access the protected information.
