public static final Creator<NsdServiceInfo> CREATOR

Implement the Parcelable interface

Public constructors

NsdServiceInfo

Added in API level 16
Also in T Extensions 3
public NsdServiceInfo ()

Public methods

describeContents

Added in API level 16
public int describeContents ()

Implement the Parcelable interface

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or CONTENTS_FILE_DESCRIPTOR

getAttributes

Added in API level 21
Also in T Extensions 3
public Map<String, byte[]> getAttributes ()

Retrieve attributes as a map of String keys to byte[] values. The attributes map is only valid for a resolved service.

The returned map is unmodifiable; changes must be made through setAttribute(String, String) and removeAttribute(String).

Returns
Map<String, byte[]>

getHost

Added in API level 16
Also in T Extensions 3
Deprecated in API level 34
public InetAddress getHost ()

This method was deprecated in API level 34.
Use getHostAddresses() to get the entire list of addresses for the host.

Get the host address. The host address is valid for a resolved service.

Returns
InetAddress

getHostAddresses

Added in API level 34
Also in T Extensions 7
public List<InetAddress> getHostAddresses ()

Get the host addresses. All host addresses are valid for the resolved service. All addresses share the same port

Returns
List<InetAddress> This value cannot be null.

getNetwork

Added in API level 33
Also in T Extensions 3
public Network getNetwork ()

Get the network where the service can be found. This is set if this NsdServiceInfo was obtained from NsdManager#discoverServices or NsdManager#resolveService, unless the service was found on a network interface that does not have a Network (such as a tethering downstream, where services are advertised from devices connected to this device via tethering).

Returns
Network This value may be null.

getPort

Added in API level 16
Also in T Extensions 3
public int getPort ()

Get port number. The port number is valid for a resolved service. The port is valid for all addresses.

Returns
int

See also:

getServiceName

Added in API level 16
Also in T Extensions 3
public String getServiceName ()

Get the service name

Returns
String

getServiceType

Added in API level 16
Also in T Extensions 3
public String getServiceType ()

Get the service type

Returns
String

removeAttribute

Added in API level 21
Also in T Extensions 3
public void removeAttribute (String key)

Remove an attribute by key

Parameters
key String

setAttribute

Added in API level 21
Also in T Extensions 3
public void setAttribute (String key, 
                String value)

Add a service attribute as a key/value pair.

Service attributes are included as DNS-SD TXT record pairs.

The key must be US-ASCII printable characters, excluding the '=' character. Values may be UTF-8 strings or null. The total length of key + value must be less than 255 bytes.

Keys should be short, ideally no more than 9 characters, and unique per instance of NsdServiceInfo. Calling setAttribute(String, String) twice with the same key will overwrite first value.

Parameters
key String

value String

setHost
