使用 WifiNetworkSpecifier 配置 wifi 接入点后无法建立连接，以下是跟踪

在使用 wifiManager 连接我的 IOT 设备时。我开始收到针对 Android 10 的 App sdk 的连接错误。最初，我开始使用 WifiNetworkSpecifier 连接到 SSID，如下所示，

val specifier = WifiNetworkSpecifier.Builder()
            .setSsid(ssid)
            .build()
val request = NetworkRequest.Builder()
            .addTransportType(NetworkCapabilities.TRANSPORT_WIFI)
            .addCapability(NetworkCapabilities.NET_CAPABILITY_NOT_RESTRICTED)
            .addCapability(NetworkCapabilities.NET_CAPABILITY_TRUSTED)
            .setNetworkSpecifier(specifier)
            .build()

    connManager.requestNetwork(request, object : ConnectivityManager.NetworkCallback() {

    override fun onAvailable(network: Network?) {
         startLocalConnection(network)
    }

    override fun onUnavailable() {
        // do failure processing here..
    }

})

在 onAvailable() 回调中连接到 SSID 后，使用自签名证书与我的本地 IOT 设备 http 服务器建立 okhttp 连接，如下所示，

fun startLocalConnection(){
    val trusted = KeyStore.getInstance("BKS")
    val rawResource = context.resources.openRawResource(R.raw.device)
    trusted.load(rawResource, "password")
    val trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm())
    trustManagerFactory.init(trusted)
    val trustManager: X509TrustManager = trustManagerFactory.trustManagers
    val sslContext = SSLContext.getInstance("TLS")
    sslContext.init(null, trustManagers, null)
    val socketFactory: SSLSocketFactory = sslContext.socketFactory
    val trustManager: X509TrustManager = trustManagers[0] as X509TrustManager

    var okHttpClient: OkHttpClient = OkHttpClient.Builder()
            .connectionSpecs(listOf(ConnectionSpec.MODERN_TLS, ConnectionSpec.COMPATIBLE_TLS))
            .build()

    val request = Request.Builder()
            .url("https://192.168.40.23/device/json")
            .build()

    okHttpClient.newCall(request).enqueue(object : Callback {
        override fun onResponse(call: Call, response: Response) {
            // Success
        }

        override fun onFailure(call: Call, e: IOException) {
            // Causing java.net.ConnectException: Failed to connect to /192.168.40.23
        }
   }}

请帮助我追踪并解决问题。

我现在有同样的问题。

在您的 onAvailable 回调中，您必须将您的网络与您的设备绑定：

((ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE))
                .bindProcessToNetwork(network);
