Question

我使用WiFi Network Request API连接到android Q上的网络。连接可用，但丢失了。这是我的代码

           public void registerNetworkCallback() {
        try {
            ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
            WifiNetworkSpecifier specifier = new WifiNetworkSpecifier.Builder()
                    .setSsid("r_guest").setWpa2Passphrase("guest").build();


            NetworkRequest networkRequest = new NetworkRequest.Builder()
                    .addTransportType(NetworkCapabilities.TRANSPORT_WIFI)
                    .removeCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET)
                    .addCapability(NetworkCapabilities.NET_CAPABILITY_NOT_RESTRICTED)
                    .addCapability(NetworkCapabilities.NET_CAPABILITY_TRUSTED)
                    .setNetworkSpecifier(specifier)
                    .build();
            NetworkRequest.Builder builder = new NetworkRequest.Builder();

            connectivityManager.requestNetwork(networkRequest, new ConnectivityManager.NetworkCallback() {
                        @Override
                        public void onAvailable(Network network) {
                            Log.d(TAG, "ConnectivityManager onAvailable");
                        }
                        @Override
                        public void onLost(Network network) {

                            Log.d(TAG, "ConnectivityManager onLost");
                        }
            );

        } catch (Exception e) {

        }
    }

我已经尝试过this solution，也遇到过帖子like this.

这些是NetworkCallBack引发的日志：

我将不胜感激吗？

WiFi网络连接在Android Q上不断断开连接
