WifiP2pGroup

public class WifiP2pGroup
extends Object implements Parcelable

java.lang.Object
↳	android.net.wifi.p2p.WifiP2pGroup

A class representing a Wi-Fi P2p group. A p2p group consists of a single group owner and one or more clients. In the case of a group with only two devices, one will be the group owner and the other will be a group client.

Constants

NETWORK_ID_PERSISTENT

Added in API level 30

 public static final int NETWORK_ID_PERSISTENT

See also:

getNetworkId()

Constant Value: -2 (0xfffffffe)

NETWORK_ID_TEMPORARY

Added in API level 30

 public static final int NETWORK_ID_TEMPORARY

The temporary network id.

See also:

getNetworkId()

Constant Value: -1 (0xffffffff)

SECURITY_TYPE_UNKNOWN

Added in API level 36

 public static final int SECURITY_TYPE_UNKNOWN

The definition of security type unknown. It is set when framework fails to derive the security type from the authentication key management provided by wpa_supplicant.

Constant Value: -1 (0xffffffff)

Added in API level 36

 public static final int SECURITY_TYPE_WPA2_PSK

The definition of security type WPA2-PSK.

Constant Value: 0 (0x00000000)

Fields

CREATOR

Added in API level 14

 public static final Creator<WifiP2pGroup> CREATOR

Public constructors

WifiP2pGroup

Added in API level 14

 public WifiP2pGroup ()

WifiP2pGroup

 public WifiP2pGroup (WifiP2pGroup source)

copy constructor

Parameters
`source`	`WifiP2pGroup`

Public methods

describeContents

Added in API level 14

 public int describeContents ()

 public Collection<WifiP2pDevice> getClientList ()

Get the list of clients currently part of the p2p group

Returns
`int`

getGroupOwnerBssid

Added in API level 36

 public MacAddress getGroupOwnerBssid ()

Returns the BSSID, if this device is the group owner of the P2P group supporting Wi-Fi Direct R2 protocol.

The interface address of a Wi-Fi Direct R2 supported device is randomized. So for every group owner session a randomized interface address will be returned.

The BSSID returned will be null, if this device is a client device or a group owner which doesn't support Wi-Fi Direct R2 protocol.

Returns
`MacAddress`	the BSSID.

getInterface

Added in API level 14

 public String getInterface ()

Get the interface name on which the group is created

Returns
`String`

The network ID of the P2P group in wpa_supplicant.

Returns
`int`

getNetworkName

Added in API level 14

 public String getNetworkName ()

Get the network name (SSID) of the group. Legacy Wi-Fi clients will discover the p2p group using the network name.

Returns
`String`

getOwner

Added in API level 14

 public WifiP2pDevice getOwner ()

Get the details of the group owner as a WifiP2pDevice object

Returns
`WifiP2pDevice`

getPassphrase

Added in API level 14

 public String getPassphrase ()

Get the passphrase of the group. This function will return a valid passphrase only at the group owner. Legacy Wi-Fi clients will need this passphrase alongside network name obtained from getNetworkName() to join the group

Returns
`String`

getSecurityType

Added in API level 36

 public int getSecurityType ()

Get the security type of the group.

Returns
`int`	One of the `SECURITY_TYPE_*`. Value is `SECURITY_TYPE_UNKNOWN`, `SECURITY_TYPE_WPA2_PSK`, `SECURITY_TYPE_WPA3_COMPATIBILITY`, or `SECURITY_TYPE_WPA3_SAE`

isGroupOwner

Added in API level 14

 public boolean isGroupOwner ()

Check whether this device is the group owner of the created p2p group

Returns
`boolean`

toString

Added in API level 14

 public String toString ()

Returns a string representation of the object.

Returns
`String`	a string representation of the object.

writeToParcel

Added in API level 14

 public void writeToParcel (Parcel dest, int flags)

Implement the Parcelable interface

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
