*** ** * ** ***
This class provides the API for managing Wi-Fi peer-to-peer connectivity. This lets an
application discover available peers, setup connection to peers and query for the list of peers.
When a p2p connection is formed over wifi, the device continues to maintain the uplink
connection over mobile or any other available network for internet connectivity on the device.
The API is asynchronous and responses to requests from an application are on listener
callbacks provided by the application. The application needs to do an initialization with
`https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#initialize(android.content.Context,%20android.os.Looper,%20android.net.wifi.p2p.WifiP2pManager.ChannelListener)` before doing any p2p operation.
Most application calls need a `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.ActionListener` instance for receiving callbacks
`https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.ActionListener#onSuccess()` or `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.ActionListener#onFailure(int)`. Action callbacks
indicate whether the initiation of the action was a success or a failure.
Upon failure, the reason of failure can be one of `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#ERROR`, `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#P2P_UNSUPPORTED`
or `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#BUSY`.
An application can initiate discovery of peers with `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#discoverPeers(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)`. An initiated
discovery request from an application stays active until the device starts connecting to a peer
,forms a p2p group or there is an explicit `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#stopPeerDiscovery(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)`.
Applications can listen to `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#WIFI_P2P_DISCOVERY_CHANGED_ACTION` to know if a peer-to-peer
discovery is running or stopped. Additionally, `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#WIFI_P2P_PEERS_CHANGED_ACTION` indicates
if the peer list has changed.
When an application needs to fetch the current list of peers, it can request the list
of peers with `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#requestPeers(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pManager.PeerListListener)`. When the peer list is available
`https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.PeerListListener#onPeersAvailable(android.net.wifi.p2p.WifiP2pDeviceList)` is called with the device list.
An application can initiate a connection request to a peer through `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#connect(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pConfig,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)`. See
`https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pConfig` for details on setting up the configuration. For communication with legacy
Wi-Fi devices that do not support p2p, an app can create a group using `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#createGroup(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pConfig,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)`
which creates an access point whose details can be fetched with `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#requestGroupInfo(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pManager.GroupInfoListener)`.
After a successful group formation through `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#createGroup(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pConfig,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)` or through `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#connect(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pConfig,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)`,
use `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#requestConnectionInfo(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pManager.ConnectionInfoListener)` to fetch the connection details. The connection info
`https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pInfo` contains the address of the group owner
`https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pInfo#groupOwnerAddress` and a flag `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pInfo#isGroupOwner` to indicate
if the current device is a p2p group owner. A p2p client can thus communicate with
the p2p group owner through a socket connection. If the current device is the p2p group owner,
`https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pInfo#groupOwnerAddress` is anonymized unless the caller holds the
`android.Manifest.permission#LOCAL_MAC_ADDRESS` permission.
With peer discovery using `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#discoverPeers(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)`, an application discovers the neighboring
peers, but has no good way to figure out which peer to establish a connection with. For example,
if a game application is interested in finding all the neighboring peers that are also running
the same game, it has no way to find out until after the connection is setup. Pre-association
service discovery is meant to address this issue of filtering the peers based on the running
services.
With pre-association service discovery, an application can advertise a service for a
application on a peer device prior to a connection setup between the devices.
Currently, DNS based service discovery (Bonjour) and Upnp are the higher layer protocols
supported. Get Bonjour resources at dns-sd.org and Upnp resources at upnp.org
As an example, a video application can discover a Upnp capable media renderer
prior to setting up a Wi-fi p2p connection with the device.
An application can advertise a Upnp or a Bonjour service with a call to
`https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#addLocalService(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.nsd.WifiP2pServiceInfo,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)`. After a local service is added,
the framework automatically responds to a peer application discovering the service prior
to establishing a p2p connection. A call to `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#removeLocalService(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.nsd.WifiP2pServiceInfo,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)` removes a local
service and `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#clearLocalServices(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)` can be used to clear all local services.
An application that is looking for peer devices that support certain services
can do so with a call to `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#discoverServices(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)`. Prior to initiating the discovery,
application can add service discovery request with a call to `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#addServiceRequest(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.nsd.WifiP2pServiceRequest,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)`,
remove a service discovery request with a call to `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#removeServiceRequest(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.nsd.WifiP2pServiceRequest,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)` or clear
all requests with a call to `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#clearServiceRequests(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)`. When no service requests remain,
a previously running service discovery will stop.
The application is notified of a result of service discovery request through listener callbacks
set through `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#setDnsSdResponseListeners(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pManager.DnsSdServiceResponseListener,%20android.net.wifi.p2p.WifiP2pManager.DnsSdTxtRecordListener)` for Bonjour or
`https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#setUpnpServiceResponseListener(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pManager.UpnpServiceResponseListener)` for Upnp.
**Note:**
Registering an application handler with `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#initialize(android.content.Context,%20android.os.Looper,%20android.net.wifi.p2p.WifiP2pManager.ChannelListener)` requires the permissions
`https://developer.android.com/reference/android/Manifest.permission#ACCESS_WIFI_STATE` and
`https://developer.android.com/reference/android/Manifest.permission#CHANGE_WIFI_STATE` to perform any further peer-to-peer
operations.

### addExternalApprover
Added in [API level 33](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void addExternalApprover (WifiP2pManager.Channel c,
MacAddress deviceAddress,
WifiP2pManager.ExternalApproverRequestListener listener)
```
Set the external approver for a specific peer.
This API associates a specific peer with an approver. When an incoming request is received
from a peer, an authorization request is routed to the attached approver. The approver then
calls `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#setConnectionRequestResult(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.MacAddress,%20int,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)` to send
the result to the WiFi service. A specific peer (identified by its `MacAddress`) can
only be attached to a single approver. The previous approver will be detached once a new
approver is attached. The approver will also be detached automatically when the channel is
closed.
When an approver is attached, `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.ExternalApproverRequestListener#onAttached(android.net.MacAddress)`
is called. When an approver is detached,
`https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.ExternalApproverRequestListener#onDetached(android.net.MacAddress,%20int)` is called.
When an incoming request is received,
`https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.ExternalApproverRequestListener#onConnectionRequested(int,%20android.net.wifi.p2p.WifiP2pConfig,%20android.net.wifi.p2p.WifiP2pDevice)`
is called. When a WPS PIN or a Wi-Fi Direct R2 pairing bootstrapping PIN is generated,
`https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.ExternalApproverRequestListener#onPinGenerated(android.net.MacAddress,%20java.lang.String)` is called.
The application must have `https://developer.android.com/reference/android/Manifest.permission#NEARBY_WIFI_DEVICES` with
android:usesPermissionFlags="neverForLocation". If the application does not declare
android:usesPermissionFlags="neverForLocation", then it must also have
`https://developer.android.com/reference/android/Manifest.permission#ACCESS_FINE_LOCATION`.
Requires `https://developer.android.com/reference/android/Manifest.permission#MANAGE_WIFI_NETWORK_SELECTION`

for the purpose of establishing a connection. See `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#discoverPeers(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)` for more details.
This method accepts a `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pDiscoveryConfig` object specifying the desired
parameters for the peer discovery. The configuration object allows the specification of the
scan type (ex. FULL, SOCIAL) and the inclusion of vendor-specific configuration data.
The application must have `https://developer.android.com/reference/android/Manifest.permission#NEARBY_WIFI_DEVICES` with
android:usesPermissionFlags="neverForLocation". If the application does not declare
android:usesPermissionFlags="neverForLocation", then it must also have
`https://developer.android.com/reference/android/Manifest.permission#ACCESS_FINE_LOCATION`.

go to the channel frequency requested via
`https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pUsdBasedLocalServiceAdvertisementConfig` and responds to a service discovery
request from a peer.
The service information is set through
`https://developer.android.com/reference/android/net/wifi/p2p/nsd/WifiP2pServiceInfo#WifiP2pServiceInfo(android.net.wifi.p2p.nsd.WifiP2pUsdBasedServiceConfig)`
The function call immediately returns after sending a request to start the service
advertisement to the framework. The application is notified of a success or failure to
start service advertisement through listener callbacks `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.ActionListener#onSuccess()` or
`https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.ActionListener#onFailure(int)`.
The service information can be cleared with calls to
`https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#removeLocalService(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.nsd.WifiP2pServiceInfo,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)` or `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#clearLocalServices(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)`.

### validateDirInfo
Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void validateDirInfo (WifiP2pManager.Channel c,
WifiP2pDirInfo dirInfo,
Executor executor,
OutcomeReceiver callback)
```
Validate the Device Identity Resolution (DIR) Information of a P2P device.
See `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pDirInfo` for details.
Framework takes the `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pDirInfo` and derives a set of Tag values based on
the cached Device Identity Keys (DevIK) of all paired peers saved in the device.
If a derived Tag value matches the Tag value received in the `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pDirInfo`, the
device is identified as a paired peer and returns true.
Use `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#isWiFiDirectR2Supported()` to determine whether the device supports
this feature. If `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#isWiFiDirectR2Supported()` return `false` then
this method will throw `https://developer.android.com/reference/java/lang/UnsupportedOperationException`.
The application must have `https://developer.android.com/reference/android/Manifest.permission#NEARBY_WIFI_DEVICES` with
android:usesPermissionFlags="neverForLocation". If the application does not declare
android:usesPermissionFlags="neverForLocation", then it must also have
`https://developer.android.com/reference/android/Manifest.permission#ACCESS_FINE_LOCATION`.
| Parameters ||
|---|---|
| `c` | `WifiP2pManager.Channel`: It is the channel created at `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#initialize(android.content.Context,%20android.os.Looper,%20android.net.wifi.p2p.WifiP2pManager.ChannelListener)`. This value cannot be `null`.

|
| `executor` | `Executor`: The executor on which callback will be invoked. This value cannot be `null`. Callback and listener events are dispatched through this `https://developer.android.com/reference/java/util/concurrent/Executor`, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use `https://developer.android.com/reference/android/content/Context#getMainExecutor()`. Otherwise, provide an `https://developer.android.com/reference/java/util/concurrent/Executor` that dispatches to an appropriate thread.
|
| `callback` | `OutcomeReceiver`: An OutcomeReceiver callback for receiving the result via `https://developer.android.com/reference/android/os/OutcomeReceiver#onResult(R)` indicating whether the DIR info of P2P device is of a paired device. {code true} for paired, `false` for not paired. When this API call fails due to permission issues, state machine is busy etc., `https://developer.android.com/reference/android/os/OutcomeReceiver#onError(E)` is called. This value cannot be `null`.
