/**
* Update the suggested qualified networks list. Network availability provider must invoke
* this method whenever the suggested qualified networks changes. If this method is never
* invoked for certain APN types, then frameworks uses its own logic to determine the
* transport to setup the data network.
*
* For example, QNS can suggest frameworks to setup IMS on IWLAN by specifying
* {@link ApnSetting#TYPE_IMS} with a list containing single element
* {@link AccessNetworkType#IWLAN}.
*
* Or if QNS consider multiple access networks are qualified for certain APN type, it can
* suggest frameworks by specifying the APN type with multiple elements in the list like
* {{@link AccessNetworkType#EUTRAN}, {@link AccessNetworkType#IWLAN}}. Frameworks will then
* first attempt to setup data on LTE network. If the device moves from LTE to UMTS, then
* frameworks can perform handover the data network to the second preferred access network
* if available.
*
* If the {@code qualifiedNetworkTypes} list is empty, it means QNS has no suggestion to the
* frameworks, and frameworks will decide the transport to setup the data network.
* Update the qualified networks list. Network availability provider must invoke this method
* whenever the qualified networks changes. If this method is never invoked for certain
* APN types, then frameworks will always use the default (i.e. cellular) data and network
* service.
*
* @param apnTypes APN types of the qualified networks. This must be a bitmask combination
* of {@link ApnType}.
* @param qualifiedNetworkTypes List of network types which are qualified for data
* connection setup for {@link @apnType} in the preferred order. Each element in the list
* is a {@link AccessNetworkType}. Note that {@link AccessNetworkType#UNKNOWN} is not a
* valid input here.
* is a {@link AccessNetworkType}. An empty list indicates no networks are qualified
* for data setup.
