Eu quero fazer um método de post HTTPS para enviar alguns dados do meu aplicativo android para o meu site.

eu useiHttpURLConnection primeiro e está funcionando bem com o meu URL HTTP. Meu site de produção está em HTTPS e quero enviar o mesmo POST usandoHttpsURLConnection. Alguém pode me ajudar a usar a aula corretamente?

Eu encontrei alguma fonte emesse link:

KeyStore keyStore = ...;    
TrustManagerFactory tmf = TrustManagerFactory.getInstance("X509");    
tmf.init(keyStore);

SSLContext context = SSLContext.getInstance("TLS");   
context.init(null, tmf.getTrustManagers(), null);

URL url = new URL("https://www.example.com/");   
HttpsURLConnection urlConnection = (HttpsURLConnection)
url.openConnection();   
urlConnection.setSSLSocketFactory(context.getSocketFactory());   
InputStream in = urlConnection.getInputStream();

Qual deve ser o valor deKeyStore keyStore = ...;?

Eu tentei enviar os dados usando o mesmoHttpURLConnection, mas estou vendo alguns dados POST perdidos ou com erro.

Eu tentei o método deessa questão. Estou colando meu código abaixo

String urlParameters="dateTime=" + URLEncoder.encode(dateTime,"UTF-8")+
    "&mobileNum="+URLEncoder.encode(mobileNum,"UTF-8");

URL url = new URL(myurl);
HttpsURLConnection conn;
conn=(HttpsURLConnection)url.openConnection();

// Create the SSL connection
SSLContext sc;
sc = SSLContext.getInstance("TLS");
sc.init(null, null, new java.security.SecureRandom());
conn.setSSLSocketFactory(sc.getSocketFactory());
conn.setConnectTimeout(HTTP_CONNECT_TIME_OUT);
conn.setReadTimeout(HTTP_READ_TIME_OUT);

//set the output to true, indicating you are outputting(uploading) POST data
conn.setDoOutput(true);
//once you set the output to true, you don't really need to set the request method to post, but I'm doing it anyway
conn.setRequestMethod("POST");
conn.setFixedLengthStreamingMode(urlParameters.getBytes().length);
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

PrintWriter out = new PrintWriter(conn.getOutputStream());
out.print(urlParameters);
out.close();

InputStream is = conn.getInputStream();
BufferedReader in = new BufferedReader(new InputStreamReader(is));
String inputLine;
while ((inputLine = in.readLine()) != null) {
  response += inputLine;            
}                   

O erro que estou recebendo está abaixo:
