+     * To register a listener, pass a {@link PhoneStateListener} which implements
+     * interfaces of events. For example,
+     * FakeServiceStateChangedListener extends {@link PhoneStateListener} implements
+     * {@link PhoneStateListener.ServiceStateChangedListener}.
+     *
+     * At registration, and when a specified telephony state changes, the telephony manager invokes
+     * the appropriate callback method on the listener object and passes the current (updated)
+     * values.
+     * <p>
+     *
+     * If this TelephonyManager object has been created with {@link #createForSubscriptionId},
+     * applies to the given subId. Otherwise, applies to
+     * {@link SubscriptionManager#DEFAULT_SUBSCRIPTION_ID}. To listen events for multiple subIds,
+     * pass a separate listener object to each TelephonyManager object created with
+     * {@link #createForSubscriptionId}. Only {@link PhoneStateListener.CallStateChangedListener}
+     * can be used to receive changes for all subIds through
+     * {@link SubscriptionManager#DEFAULT_SUBSCRIPTION_ID}.
+     *
+     * Note: if you call this method while in the middle of a binder transaction, you <b>must</b>
+     * call {@link android.os.Binder#clearCallingIdentity()} before calling this method. A
+     * {@link SecurityException} will be thrown otherwise.
+     *
+     * This API should be used sparingly -- large numbers of listeners will cause system
+     * instability. If a process has registered too many listeners without unregistering them, it
+     * may encounter an {@link IllegalStateException} when trying to register more listeners.
