WifiAwareNetworkInfo
public
final
class
WifiAwareNetworkInfo
extends Object
implements
TransportInfo,
Parcelable
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 |
