setSubtype

Added in API level 35
Also in T Extensions 12
public DiscoveryRequest.Builder setSubtype (String subtype)

Sets the optional subtype of the services to be discovered. If a non-empty subtype is specified, it must start with underscore ('_') and have the trailing "._sub" removed. Otherwise, NsdManager.discoverServices will fail with ERROR(NsdManager.FAILURE_BAD_PARAMETER/android.net.nsd.NsdManager#FAILURE_BAD_PARAMETER NsdManager.FAILURE_BAD_PARAMETER). For example, subtype should be "_printer" for DNS name "_printer._sub._http._tcp". In this case, only services with this subtype will be queried, rather than all services of the base service type. Note that a non-empty service type must be specified with ERROR(/#setServiceType) if a non-empty subtype is specified by this method.

Parameters
subtype String: This value may be null.

Returns
DiscoveryRequest.Builder This value cannot be null.
