58/**
59 * Provides access to information about the telephony services on
60 * the device. Applications can use the methods in this class to
61 * determine telephony services and states, as well as to access some
62 * types of subscriber information. Applications can also register
63 * a listener to receive notification of telephony state changes.
64 * <p>
65 * You do not instantiate this class directly; instead, you retrieve
66 * a reference to an instance through
67 * {@link android.content.Context#getSystemService
68 * Context.getSystemService(Context.TELEPHONY_SERVICE)}.
69 *
70 * The returned TelephonyManager will use the default subscription for all calls.
71 * To call an API for a specific subscription, use {@link #createForSubscriptionId(int)}. e.g.
72 * <code>
73 *   telephonyManager = defaultSubTelephonyManager.createForSubscriptionId(subId);
74 * </code>
75 * <p>
76 * Note that access to some telephony information is
77 * permission-protected. Your application cannot access the protected
78 * information unless it has the appropriate permissions declared in
79 * its manifest file. Where permissions apply, they are noted in the
80 * the methods through which you access the protected information.
