Connecting to a web service over a Secure Sockets Layer SSL protocol

Android default HttpClinet does not support SSL connections, so if you have a secured web service, you need to connect to it via javax.net.ssl.HttpsURLConnection.
if you want to call a SSL SOAP web service:

String CallWebService(String url,
 String soapAction,
 String envelope) throws IOException {
 URL address=new URL(url);
 URLConnection connection=address.openConnection();
 HttpsURLConnection post=(HttpsURLConnection)connection;
 post.setDoInput(true);
 post.setDoOutput(true);
 post.setRequestMethod("POST");
 post.setRequestProperty("SOAPAction", soapAction);
 post.setRequestProperty( "Content-type", "text/xml; charset=utf-8" );
 post.setRequestProperty( "Content-Length", String.valueOf(envelope.length()));
 post.setReadTimeout(4000);
 
 OutputStream outStream=post.getOutputStream();
 Writer out=new OutputStreamWriter(outStream);
 out.write(envelope);
 out.flush();
 out.close();
 
 
 InputStream inStream = post.getInputStream();
 BufferedInputStream in = new BufferedInputStream(inStream,4);
 StringBuffer buffer=new StringBuffer();
 // read 4 bytes a time
 byte[] buffArray=new byte[4];
 int c=0;
 while((c=in.read(buffArray))!=-1){
 for(int i=0;i<c;i++)
 buffer.append((char)buffArray[i]);
 }

 return buffer.toString();
 }
