WifiAwareNetworkInfo
public final class WifiAwareNetworkInfo
extends Object
implements Parcelable, TransportInfo
java.lang.Object | |
↳ | android.net.wifi.aware.WifiAwareNetworkInfo |
Wi-Fi Aware-specific network information. The information can be extracted from the NetworkCapabilities
of the network using NetworkCapabilities.getTransportInfo()
. The NetworkCapabilities
is provided by the connectivity service to apps, e.g. received through the ConnectivityManager.NetworkCallback.onCapabilitiesChanged(android.net.Network, android.net.NetworkCapabilities)
callback.
The Wi-Fi Aware-specific network information include the peer's scoped link-local IPv6 address for the Wi-Fi Aware link, as well as (optionally) the port and transport protocol specified by the peer. The scoped link-local IPv6, port, and transport protocol can then be used to create a Socket
connection to the peer.
Note: these are the peer's IPv6 and port information - not the local device's!

Fields
Public methods
describeContents
public int describeContents ()
Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int)
, the return value of this method must include the CONTENTS_FILE_DESCRIPTOR
bit.
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 |
getChannelInfoList
public List<WifiAwareChannelInfo> getChannelInfoList ()
Get a list WifiAwareChannelInfo
which is used by this Aware data-path
Returns | |
---|---|
List<WifiAwareChannelInfo> | A list of WifiAwareChannelInfo This value cannot be null . |
getPeerIpv6Addr
public Inet6Address getPeerIpv6Addr ()
Get the scoped link-local IPv6 address of the Wi-Fi Aware peer (not of the local device!).
Returns | |
---|---|
Inet6Address | An IPv6 address. This value may be null . |
getPort
public int getPort ()
Get the port number to be used to create a network connection to the Wi-Fi Aware peer. The port information is provided by the app running on the peer which requested the connection, using the WifiAwareNetworkSpecifier.Builder.setPort(int)
.
Returns | |
---|---|
int | A port number on the peer. A value of 0 indicates that no port was specified by the peer. |
getTransportProtocol
public int getTransportProtocol ()
Get the transport protocol to be used to communicate over a network connection to the Wi-Fi Aware peer. The transport protocol is provided by the app running on the peer which requested the connection, using the WifiAwareNetworkSpecifier.Builder.setTransportProtocol(int)
.
The transport protocol number is assigned by the Internet Assigned Numbers Authority (IANA) https://www.iana.org/assignments/protocol-numbers/protocol-numbers.xhtml.
Returns | |
---|---|
int | A transport protocol id. A value of -1 indicates that no transport protocol was specified by the peer. |
toString
public String toString ()
Returns a string representation of the object.
Returns | |
---|---|
String | a string representation of the object. |
writeToParcel
public void writeToParcel (Parcel dest, int flags)
Flatten this object in to a Parcel.
Parameters | |
---|---|
dest | Parcel : The Parcel in which the object should be written. This value cannot be null . |
flags | int : Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE . Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE , and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
