You may want to try Jt secure Web Services for Android: -Java Pattern Oriented Framework, An application of the Messaging Design Pattern IBM Technical Library http://www.ibm.com/developerworks/webservices/library/ws-designpattern/index.html
- Messaging Design Pattern and a distributed Component/Service Model https://jt.dev.java.net/files/documents/5553/149793/MDPdistributedModel.pdf The following code is taken from the Jt.JtURL component (invoked by the Jt.rest.JtRestService component) private String doPost (String request) { URLConnection urlConn; URL destURL; DataOutputStream outStream; DataInputStream inStream; int c; StringBuffer sBuffer = new StringBuffer (); if (request == null) return null; if (url == null) return null; handleTrace ("request:" + request); try { destURL = new URL (url); urlConn = destURL.openConnection(); urlConn.setDoOutput(true); urlConn.setDoInput(true); urlConn.setRequestProperty("Content-length", "" + request.length()); outStream = new DataOutputStream (urlConn.getOutputStream()); outStream.writeBytes(request); outStream.close (); inStream = new DataInputStream (urlConn.getInputStream()); while ((c = inStream.read()) >= 0) { sBuffer.append((char) c); } } catch (Exception ex) { handleException (ex); } return ((String) sBuffer.toString()); } If feasible you may want to try without GZIP. It should be a bit faster. On Nov 18, 6:00 pm, Wipeout <4.9fi...@gmail.com> wrote: > Hey guys, > This is my first post to the Android Developers group.
