WifiAwareNetworkInfo

Kotlin |Java

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!

Summary

Inherited constants

From interface android.os.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(Parcel, int)`: 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)`".

Fields
`public static final Creator<WifiAwareNetworkInfo>`	`CREATOR`

Public methods
`int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`List<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()` Returns a string representation of the object.
`void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

From interface


        
          android.os.Parcelable

`abstract int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`abstract void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

Fields

CREATOR

Added in API level 29

public static final Creator<WifiAwareNetworkInfo> CREATOR

Public methods

describeContents

Added in API level 29

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

Added in API level 33

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

Added in API level 29

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

Added in API level 29

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

Added in API level 29

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

Added in API level 29

public String toString ()

Returns a string representation of the object.

Returns
`String`	a string representation of the object.

writeToParcel

Added in API level 29

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
