Android 10 connect to specific wifi but no internet connection

Question

I connect to wifi by code below, It can connect successful but no internet connection (android show icon network with x), don't know why.

WifiNetworkSpecifier wifiNetworkSpecifier = new WifiNetworkSpecifier.Builder()
    .setSsid(ssid)
    .setWpa2Passphrase(password)
    .build();

NetworkRequest networkRequest = new NetworkRequest.Builder()
        .addTransportType(NetworkCapabilities.TRANSPORT_WIFI)
        .setNetworkSpecifier(wifiNetworkSpecifier)
        .build();

connectivityManager = (ConnectivityManager)activity.getSystemService(Context.CONNECTIVITY_SERVICE);

networkCallback = new ConnectivityManager.NetworkCallback() {
    @Override
    public void onAvailable(@NonNull Network network) {
        super.onAvailable(network);
        connectivityManager.bindProcessToNetwork(network);
    }
};
connectivityManager.requestNetwork(networkRequest, networkCallback);

In onAvailable set the network on wifi. network.. Your compiler will let you choose the function which i forgot the name of. — blackapps

Thanks but can you explain more, I still don't know what function need to use. I searching a lot and found that link may problem come from android 10: issuetracker.google.com/issues/138335744. Still don't know how to workaround it. — QHu91_IT

I forgot the name. But if you just type network. in Android Studio you are presented with a lot of functions to choose from. Which one to choose should be clear then. Now does AS act as i said? — blackapps

Change your network request

val networkRequest: NetworkRequest = NetworkRequest.Builder()
                    .addTransportType(NetworkCapabilities.TRANSPORT_WIFI)
                    .addCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET)
                    .setNetworkSpecifier(wifiNetworkSpecifier)
                    .build()

But I got an issue when I called to request to add a network again, networkCallback called in onUnavailable, and nothing to do.
