WifiP2pDirInfo

Kotlin |Java

class WifiP2pDirInfo : Parcelable

kotlin.Any
↳	android.net.wifi.p2p.WifiP2pDirInfo

This object contains the Device Identity Resolution (DIR) Info to check if the device is a previously paired device. The device advertises this information in Bluetooth LE advertising packets and Unsynchronized Service Discovery (USD) frames. The device receiving DIR Info uses this information to identify that the peer device is a previously paired device. For Details, refer Wi-Fi Alliance Wi-Fi Direct R2 specification section 3.8.2 Pairing Identity and section 3.9.2.3.2 Optional Advertising Data Elements.

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 constructors

WifiP2pDirInfo

Added in API level Baklava

WifiP2pDirInfo(
    macAddress: MacAddress, 
    nonce: ByteArray, 
    dirTag: ByteArray)

Constructor for Device Identity Resolution (DIR) Info generated based on the 128 bit Device Identity key. For details, refer Wi-Fi Alliance Wi-Fi Direct R2 specification Table 8.

Parameters
`macAddress`	MacAddress: The MAC address of the P2P device interface. This value cannot be `null`.
`nonce`	ByteArray: Random number of 8 octets. This value cannot be `null`.
`dirTag`	ByteArray: Resolvable identity value of 8 octets derived based on the device MAC address, device identity key and P2P device MAC address. Tag = Truncate-64(HMAC-SHA-256(DevIk, "DIR" \|\| P2P Device Address \|\| Nonce)) This value cannot be `null`.

Public methods

describeContents

Added in API level Baklava

fun describeContents(): Int

Implement the Parcelable interface

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`

getDirTag

Added in API level Baklava

fun getDirTag(): ByteArray

Get the DIR Tag value. See WifiP2pDirInfo

Return
`ByteArray`	A byte-array of Tag value of size 8 octets. This value cannot be `null`.

getMacAddress

Added in API level Baklava

fun getMacAddress(): MacAddress

Return
`MacAddress`	the MAC address of the P2P device interface. This value cannot be `null`.

getNonce

Added in API level Baklava

fun getNonce(): ByteArray

Get the nonce value used to derive DIR Tag. See WifiP2pDirInfo

Return
`ByteArray`	A byte-array of random number of size 8 octets. This value cannot be `null`.

toString

Added in API level Baklava

fun toString(): String

Generates a string of all the defined elements.

Return
`String`	a compiled string representing all elements

writeToParcel

Added in API level Baklava

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

Implement the Parcelable interface

Parameters
`dest`	Parcel: 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 Baklava

static val CREATOR: Parcelable.Creator<WifiP2pDirInfo!>
