Android 10 (API 수준 29) 이상 기기에서는 새로운 P2P API를 사용하여 Chromecast 및 Google Home 하드웨어와 같은 보조 기기의 구성을 부트스트랩할 수 있습니다. 이 기능을 사용하면 앱에서 요청된 네트워크의 속성을 설명할 수 있는 WifiNetworkSpecifier를 사용해 기기가 연결되는 액세스 포인트를 변경하라는 메시지를 사용자에게 표시할 수 있습니다.
피어 기기 연결 요청을 시작하면 기기 사용자가 연결 요청을 수락할 수 있도록 동일한 기기에서 대화상자가 시작됩니다.
사용자 승인 우회
사용자가 특정 앱의 요청에 응답하여 네트워크 연결을 승인하면 기기에서 특정 액세스 포인트에 관한 승인을 저장합니다.
앱에서 동일한 액세스 포인트에 다시 연결하도록 특별히 요청하는 경우 기기에서는 사용자 승인 단계를 건너뛰고 자동으로 네트워크에 연결합니다. API에서 요청한 네트워크에 연결되어 있는 동안 사용자가 네트워크를 삭제하면 앱과 네트워크의 이러한 조합에 관해 저장된 승인이 삭제되며, 사용자는 이후에 그 앱에서 발생하는 모든 요청을 다시 승인해야 합니다. 앱에서 SSID 또는 BSSID 패턴 등 일반적인 요청을 하는 경우 사용자는 요청을 승인해야 합니다.

This feature enables your app to prompt the user to change the access\npoint that the device is connected to by using\n[`WifiNetworkSpecifier`](/reference/android/net/wifi/WifiNetworkSpecifier)\nto describe properties of a requested network.\n\nTo use this API, do the following:\n\n1. Create a Wi-Fi network specifier using\n [`WifiNetworkSpecifier.Builder`](/reference/android/net/wifi/WifiNetworkSpecifier.Builder).\n\n2. Set a network filter to match networks to connect to, along with required\n credentials.\n\n3. Decide on a combination of [`SSID`](/reference/android/net/wifi/WifiNetworkSpecifier.Builder#setssid),\n [`SSID pattern`](/reference/android/net/wifi/WifiNetworkSpecifier.Builder#setssidpattern),\n [`BSSID`](/reference/android/net/wifi/WifiNetworkSpecifier.Builder#setbssid),\n and [`BSSID pattern`](/reference/android/net/wifi/WifiNetworkSpecifier.Builder#setbssidpattern)\n to set the network filter in each request, subject to the following\n requirements:\n\n - Each request should provide at least one of `SSID`, `SSID pattern`, `BSSID`, or `BSSID pattern`\n - Each request can set only one of `SSID` or `SSID pattern`\n - Each request can set only one of `BSSID` or `BSSID pattern`\n4. Add the specifiers to the network request along with a\n [`NetworkCallback`](/reference/android/net/ConnectivityManager.NetworkCallback)\n instance to track the status of the request.\n\n If the user accepts the request and the connection to the network is\n successful,\n [`NetworkCallback.onAvailable()`](/reference/android/net/ConnectivityManager.NetworkCallback#onAvailable(android.net.Network))\n is invoked on the callback object. If the user denies the request or if the\n connection to the network is unsuccessful,\n [`NetworkCallback.onUnavailable()`](/reference/android/net/ConnectivityManager.NetworkCallback#onUnavailable())\n is invoked on the callback object.\n\nInitiating the request to connect to a peer device launches a dialog box on the\nsame device, from which that device's user can accept the connection request.\n| **Note:** Creating a connection using this API does not provide an internet connection to the app or to the device. To provide an internet connection to the apps on a device, use the [Wi-Fi Suggestion API](/develop/connectivity/wifi/wifi-suggest) instead.\n\nBypassing user approval\n\nOnce the user approves a network to connect to in response to a request from a\nspecific app, the device stores the approval for the particular access point.\nIf the app makes a specific request to\nconnect to that access point again, the device skips the user approval phase\nand automatically connects to the network. If the user chooses to forget the\nnetwork while connected to a network requested by the API, then this stored\napproval for that combination of app and network is removed, and any future\nrequest from the app must be approved by the user again. If the app\nmakes a non-specific request, such as with an SSID or BSSID pattern, then the\nuser must approve the request.\n\nCode sample\n\nThe following code sample shows how to connect to an open network with an SSID\nprefix of `\"test\"` and a BSSID OUI of `\"10:03:23\"`: \n\nKotlin \n\n```kotlin\nval specifier = WifiNetworkSpecifier.Builder()\n .setSsidPattern(PatternMatcher(\"test\", PatternMatcher.PATTERN_PREFIX))\n .setBssidPattern(MacAddress.fromString(\"10:03:23:00:00:00\"), MacAddress.fromString(\"ff:ff:ff:00:00:00\"))\n .build()\n\nval request = NetworkRequest.Builder()\n .addTransportType(NetworkCapabilities.TRANSPORT_WIFI)\n .removeCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET)\n .setNetworkSpecifier(specifier)\n .build()\n\nval connectivityManager = context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager\n\nval networkCallback = object : ConnectivityManager.NetworkCallback() {\n ...\n override fun onAvailable(network: Network?) {\n // do success processing here..\n }\n\n override fun onUnavailable() {\n // do failure processing here..\n }\n ...\n}\nconnectivityManager.requestNetwork(request, networkCallback)\n...\n// Release the request when done.\nconnectivityManager.unregisterNetworkCallback(networkCallback)\n```\n\nJava \n\n```java\nfinal NetworkSpecifier specifier =\n new WifiNetworkSpecifier.Builder()\n .setSsidPattern(new PatternMatcher(\"test\", PatternMatcher.PATTERN_PREFIX))\n .setBssidPattern(MacAddress.fromString(\"10:03:23:00:00:00\"), MacAddress.fromString(\"ff:ff:ff:00:00:00\"))\n .build();\n\nfinal NetworkRequest request =\n new NetworkRequest.Builder()\n .addTransportType(NetworkCapabilities.TRANSPORT_WIFI)\n .removeCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET)\n .setNetworkSpecifier(specifier)\n .build();\n\nfinal ConnectivityManager connectivityManager = (ConnectivityManager)\n context.getSystemService(Context.CONNECTIVITY_SERVICE);\n\nfinal NetworkCallback networkCallback = new NetworkCallback() {\n ...\n @Override\n void onAvailable(...) {\n // do success processing here..\n }\n\n @Override\n void onUnavailable(...) {\n // do failure processing here..\n }\n ...\n};\nconnectivityManager.requestNetwork(request, networkCallback);\n...\n// Release the request when done.\nconnectivityManager.unregisterNetworkCallback(networkCallback);\n```"]]
