WifiAwareNetworkInfo

Kotlin |Java

class WifiAwareNetworkInfo : Parcelable, TransportInfo

kotlin.Any
↳	android.net.wifi.aware.WifiAwareNetworkInfo

Wi-Fi Aware-specific network information. The information can be extracted from the android.net.NetworkCapabilities of the network using NetworkCapabilities.getTransportInfo(). The NetworkCapabilities is provided by the connectivity service to apps, e.g. received through the android.net.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 java.net.Socket connection to the peer.

Note: these are the peer's IPv6 and port information - not the local device's!

Summary

Inherited constants

From class Parcelable

Int

CONTENTS_FILE_DESCRIPTOR

Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor.

Int

PARCELABLE_WRITE_RETURN_VALUE

Flag for use with writeToParcel: the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)". Some implementations may want to release resources at this point.

Public methods
Int	`describeContents()`
MutableList<WifiAwareChannelInfo!>	`getChannelInfoList()` Get a list `WifiAwareChannelInfo` which is used by this Aware data-path
Inet6Address?	`getPeerIpv6Addr()` Get the scoped link-local IPv6 address of the Wi-Fi Aware peer (not of the local device!).
Int	`getPort()` Get the port number to be used to create a network connection to the Wi-Fi Aware peer.
Int	`getTransportProtocol()` Get the transport protocol to be used to communicate over a network connection to the Wi-Fi Aware peer.
String	`toString()`
Unit	`writeToParcel(dest: Parcel, flags: Int)`

Public methods

describeContents

Added in API level 29

fun describeContents(): Int

Return
`Int`	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR`

getChannelInfoList

Added in API level 33

fun getChannelInfoList(): MutableList<WifiAwareChannelInfo!>

Get a list WifiAwareChannelInfo which is used by this Aware data-path

Return
`MutableList<WifiAwareChannelInfo!>`	A list of `WifiAwareChannelInfo` This value cannot be `null`.

getPeerIpv6Addr

Added in API level 29

fun getPeerIpv6Addr(): Inet6Address?

Get the scoped link-local IPv6 address of the Wi-Fi Aware peer (not of the local device!).

Return
`Inet6Address?`	An IPv6 address. This value may be `null`.

getPort

Added in API level 29

fun getPort(): Int

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).

Return
`Int`	A port number on the peer. A value of 0 indicates that no port was specified by the peer.

getTransportProtocol

Added in API level 29

fun getTransportProtocol(): Int

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.

Return
`Int`	A transport protocol id. A value of -1 indicates that no transport protocol was specified by the peer.

toString

Added in API level 29

fun toString(): String

Return
`String`	a string representation of the object.

writeToParcel

Added in API level 29

fun writeToParcel(
    dest: Parcel, 
    flags: Int
): Unit

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_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `android.os.Parcelable#PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES

Properties

CREATOR

Added in API level 29

static val CREATOR: Parcelable.Creator<WifiAwareNetworkInfo!>
