HttpsUrlConnection с клиентским подписанным сертификатом в AndroidStudio

Question

спасибо заранее. У меня есть страница подключения, которая имеет метод HTTPurlConnection и менеджер доверия, который позволяет все сертификаты без какой-либо проверки подлинности. Теперь я хочу подключить URL-адрес «HTTPS», а также аутентифицировать сертификат, подписанный клиентом, который я сохранил в папке raw. Хотя в Google есть много примеров, я не знаю, как и с чего начать? пожалуйста, направь меня. Я приложил обе страницы для справки.

    public String checkprogress(SoapObject value, String action, String url) throws TimeoutException {
        try {

            URL urlCon = new URL(url);
            httpURLConnection = (HttpURLConnection) urlCon.openConnection();
            httpURLConnection.connect();

            envelope.bodyOut = value;
