Android server-client application session issue

Question

I am developing server client application on android and i am using session on server side of application but sometimes i lost my session on server. Ps: i use https connection on server.

I am using these to hold session:

• I am using single instance DefaultHttpClient and use it for all http requests.
• I use only httpPost method

• I use only https certificate:

  schemeRegistry.register(new Scheme("https", sslSocketFactory, 443)); ClientConnectionManager cm = new ThreadSafeClientConnManager(params, schemeRegistry);

• I save my cookies after all http requests:

  private void createSessionCookie(){

  List<Cookie> cookies = httpclient.getCookieStore().getCookies();
  
  if (! cookies.isEmpty()){
  
      CookieSyncManager.createInstance(ctx);
      CookieManager cookieManager = CookieManager.getInstance();
  
      //sync all the cookies in the httpclient with the webview by generating cookie string
      for (Cookie cookie : cookies){
  
          Cookie sessionInfo = cookie;
  
          String cookieString = sessionInfo.getName() + "=" + sessionInfo.getValue() + "; domain=" + sessionInfo.getDomain();
          cookieManager.setCookie(UrlConstants.SERVICE_PRE_URL, cookieString);
          CookieSyncManager.getInstance().sync();
      }
  }
  

  }

Even though i am doing these, i lose session. Please help me to solve this problem, Thanks for any advice Best Regards.

Answer 1

You should not do anything with cookies manually, just create static CookieStore somewhere, assign it to the HttpContext, and use that context in your requests. Cookies will be saved and restored automagically.

These are your class members:

private static CookieStore cookieStore = new BasicCookieStore();
private HttpClient httpclient = new DefaultHttpClient();
private HttpPost post = new HttpPost("your url here");

And this part goes into the member function, which does the request:

HttpContext ctx = new BasicHttpContext();
ctx.setAttribute(ClientContext.COOKIE_STORE, cookieStore);

HttpResponse result = httpclient.execute(post,ctx);
