How to connect to Other Wi-fi Network Programmatically in and above Android API level 29 (>= 29)

Question

Usecase: Connect to other specified Wi-fi networks successfully and disconnect from the existing Wi-fi network.

I tried WifiNetworkSpecifier and WifiNetworkSuggestion to connect to Other Wi-fi programmatically in Android. When I tried using WifiNetworkSpecifier, I can see the dialog asking the user to connect to the specified network. But, after clicking connect I can not access the internet and disconnects from the Wi-fi network when I close/kill my application. Whereas WifiNetworkSuggestion is not working for me with the below code(location permission garanted).

Code used for WifiNetworkSpecifier:

    WifiNetworkSpecifier.Builder builder = new WifiNetworkSpecifier.Builder();
    builder.setSsid(MY_SSID);
    builder.setWpa2Passphrase(MY_PASSWORD);

    WifiNetworkSpecifier wifiNetworkSpecifier = builder.build();

    NetworkRequest.Builder networkRequestBuilder1 = new NetworkRequest.Builder();
    networkRequestBuilder1.addTransportType(NetworkCapabilities.TRANSPORT_WIFI);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        networkRequestBuilder1.setNetworkSpecifier(wifiNetworkSpecifier);
    }

    NetworkRequest networkRequest = networkRequestBuilder1.build();
    ConnectivityManager cm = (ConnectivityManager)
            getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE);
    ConnectivityManager.NetworkCallback networkCallback = new
            ConnectivityManager.NetworkCallback() {
                @Override
                public void onAvailable(Network network) {
                    super.onAvailable(network);
                    Log.d(TAG, "onAvailable:" + network);
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                        cm.bindProcessToNetwork(network);
                    }
                }
            };
    cm.requestNetwork(networkRequest, networkCallback);

Code used for WifiNetworkSuggestion (I think for my usecase I need to use this one as per the android documentation):

   WifiNetworkSuggestion suggestion1 = new WifiNetworkSuggestion.Builder()
            .setSsid(MY_SSID)
            .setWpa2Passphrase(MY_PASSWORD)
            .setIsAppInteractionRequired(true) // Optional (Needs location permission)
            .build();


    List<WifiNetworkSuggestion> suggestionsList = new ArrayList<WifiNetworkSuggestion>();
    suggestionsList.add(suggestion1);

    int status = wifiManager.addNetworkSuggestions(suggestionsList);

    if (status != WifiManager.STATUS_NETWORK_SUGGESTIONS_SUCCESS) {
        showToast("Failure");
    } else {
        showToast("Success");
    }

    final IntentFilter intentFilter = new IntentFilter(WifiManager.ACTION_WIFI_NETWORK_SUGGESTION_POST_CONNECTION);

    final BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            if (!intent.getAction().equals(WifiManager.ACTION_WIFI_NETWORK_SUGGESTION_POST_CONNECTION)) {
                return;
            }
            // Post connection
            showToast("post connection");
        }
    };
    getApplicationContext().registerReceiver(broadcastReceiver, intentFilter);

Permissions used:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />

Any suggestions or help is much appreciated. Thank you!

In my case the above code is working but I disconnected the network from wifi picker so it blocked me for 24 hours. That is the reason above din’t worked for me at that time. Few limitations which I observed.

• Location Permission is Mandatory
• A user declining the network suggestion notification removes the CHANGE_WIFI_STATE permission from the app i.e; When the user click “No” in notification. They cannot able to connect to Wi-fi. The user can grant this approval later by going into the Wi-Fi control menu (Settings > Apps & notifications > Special App access > Wi-Fi Control > App name)- Android Documentation. 
• After successfully connected to wifi uninstalling the app will leads to disconnection in WifiNetwork
