Working with HttpsUrlConnection

Refer this doc over HttpsUrlConnection.
To create key and import certificate use Portecle tool.
To create key using Keytool, follow the doc.


String query = "emailId=" + URLEncoder.encode("xxx@gmail.com", HTTP.UTF_8) + "&pwd=" + URLEncoder.encode("password", HTTP.UTF_8);


HttpsURLConnection urlConnection = null;
try{
    KeyStore keyStore = KeyStore.getInstance("BKS");
    InputStream in =  
    getResources().openRawResource(R.raw.keystore);
    keyStore.load(in, "password".toCharArray());
    TrustManagerFactory tmf = 
    TrustManagerFactory.getInstance("X509");
    tmf.init(keyStore);


    SSLContext context = SSLContext.getInstance("TLS");
    context.init(null, tmf.getTrustManagers(), null);
    System.setProperty("http.keepAlive", "false");
    URL url = new URL("https://www.google.co.in/");
    urlConnection = (HttpsURLConnection) url.openConnection();

    urlConnection.setDoInput(true);
    urlConnection.setDoOutput(true);
    urlConnection.setRequestMethod("POST");

     //To post data...
     DataOutputStream output = new DataOutputStream( urlConnection.getOutputStream() );
     output.writeBytes( query );
     output.flush();
     output.close();

     InputStream stream = null;


     if ( urlConnection.getResponseCode() == 201 )
stream = urlConnection.getInputStream();
     else
       //Report error...

     urlConnection.disconnect();


}catch(Exception e){
