Added in API level 35
Also in T Extensions 12

public Builder (String serviceType)

Creates a new default Builder object with given service type.

Parameters
`serviceType`	`String`: This value cannot be `null`.

Throws
`IllegalArgumentException`	if `serviceType` is `null` or an empty string

Public methods

build

Added in API level 35
Also in T Extensions 12

public DiscoveryRequest build ()

Creates a new DiscoveryRequest object.

Returns
`DiscoveryRequest`	This value cannot be `null`.

setNetwork

Added in API level 35
Also in T Extensions 12

public DiscoveryRequest.Builder setNetwork (Network network)

Sets the Network on which the discovery queries should be sent.

Parameters
`network`	`Network`: the discovery network or `null` if the query should be sent on all supported networks

Returns
`DiscoveryRequest.Builder`	This value cannot be `null`.

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`.
