Added in [API level 14](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) # android.net.wifi.p2p *** ** * ** *** Provides classes to create peer-to-peer (P2P) connections with Wi-Fi Direct. Using these APIs, you can discover and connect to other devices when each device supports Wi-Fi Direct, then communicate over a speedy connection across distances much longer than a Bluetooth connection. The primary class you need to work with is `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager`, which you can acquire by calling `https://developer.android.com/reference/android/content/Context#getSystemService(java.lang.Class)`. The `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager` includes APIs that allow you to: - Initialize your application for P2P connections by calling `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#initialize(android.content.Context,%20android.os.Looper,%20android.net.wifi.p2p.WifiP2pManager.ChannelListener)` - Discover nearby devices by calling `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#discoverPeers(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pManager.ActionListener)` - Start a P2P connection by calling `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)` - And more Several other interfaces and classes are necessary as well, such as: - The `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.ActionListener` interface allows you to receive callbacks when an operation such as discovering peers or connecting to them succeeds or fails. - `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.PeerListListener` interface allows you to receive information about discovered peers. The callback provides a `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pDeviceList`, from which you can retrieve a `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pDevice` object for each device within range and get information such as the device name, address, device type, the WPS configurations the device supports, and more. - The `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.GroupInfoListener` interface allows you to receive information about a P2P group. The callback provides a `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pGroup` object, which provides group information such as the owner, the network name, and passphrase. - `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.ConnectionInfoListener` interface allows you to receive information about the current connection. The callback provides a `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pInfo` object, which has information such as whether a group has been formed and who is the group owner. In order to use the Wi-Fi P2P APIs, your app must request the following user permissions: - `https://developer.android.com/reference/android/Manifest.permission#ACCESS_WIFI_STATE` - `https://developer.android.com/reference/android/Manifest.permission#CHANGE_WIFI_STATE` - `https://developer.android.com/reference/android/Manifest.permission#INTERNET` (although your app doesn\\u2019t technically connect to the Internet, communicating to Wi-Fi Direct peers with standard java sockets requires Internet permission). For example code, see the [Wi-Fi Direct Demo](https://developer.android.com/resources/samples/WiFiDirectDemo) sample application. **Note:** Not all Android-powered devices support Wi-Fi Direct. If your application uses Wi-Fi Direct, declare so with a [``](https://developer.android.com/guide/topics/manifest/uses-feature-element) element in the manifest file: ``` ... ``` ## Interfaces |---|---| | [WifiP2pManager.ActionListener](https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.ActionListener) | Interface for callback invocation on an application action | | [WifiP2pManager.ChannelListener](https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.ChannelListener) | Interface for callback invocation when framework channel is lost | | [WifiP2pManager.ConnectionInfoListener](https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.ConnectionInfoListener) | Interface for callback invocation when connection info is available | | [WifiP2pManager.DeviceInfoListener](https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.DeviceInfoListener) | Interface for callback invocation when `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pDevice` is available in response to `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#requestDeviceInfo(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pManager.DeviceInfoListener)`. | | [WifiP2pManager.DiscoveryStateListener](https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.DiscoveryStateListener) | Interface for callback invocation when p2p state is available in response to `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#requestDiscoveryState(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pManager.DiscoveryStateListener)`. | | [WifiP2pManager.DnsSdServiceResponseListener](https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.DnsSdServiceResponseListener) | Interface for callback invocation when Bonjour service discovery response is received | | [WifiP2pManager.DnsSdTxtRecordListener](https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.DnsSdTxtRecordListener) | Interface for callback invocation when Bonjour TXT record is available for a service | | [WifiP2pManager.ExternalApproverRequestListener](https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.ExternalApproverRequestListener) | Interface for callback invocation when an incoming request is received. | | [WifiP2pManager.GroupInfoListener](https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.GroupInfoListener) | Interface for callback invocation when group info is available | | [WifiP2pManager.NetworkInfoListener](https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.NetworkInfoListener) | Interface for callback invocation when `https://developer.android.com/reference/android/net/NetworkInfo` is available in response to `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#requestNetworkInfo(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pManager.NetworkInfoListener)`. | | [WifiP2pManager.P2pStateListener](https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.P2pStateListener) | Interface for callback invocation when p2p state is available in response to `https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#requestP2pState(android.net.wifi.p2p.WifiP2pManager.Channel,%20android.net.wifi.p2p.WifiP2pManager.P2pStateListener)`. | | [WifiP2pManager.PeerListListener](https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.PeerListListener) | Interface for callback invocation when peer list is available | | [WifiP2pManager.ServiceResponseListener](https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.ServiceResponseListener) | Interface for callback invocation when service discovery response other than Upnp or Bonjour is received | | [WifiP2pManager.UpnpServiceResponseListener](https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.UpnpServiceResponseListener) | Interface for callback invocation when upnp service discovery response is received | | [WifiP2pManager.WifiP2pListener](https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.WifiP2pListener) | Interface used to listen to Wi-Fi p2p various changes such as device state change, discovery started/stopped, connection change, etc. | ##
