managing Cookies in HttpPost

For using Cookie store In Application and

public class MyApplication extends Application {
 public String cookie = null;
 private static HttpURLConnection conn = null;
 public static CookieStore cookieStore;
 public static HttpContext localContext;
 
     @Override
 public void onCreate() {
     // TODO Auto-generated method stub
     super.onCreate();
     CookieSyncManager.createInstance(this);
     cookie = null;
     cookieStore = new BasicCookieStore();
     localContext = new BasicHttpContext();
 
 }
 
 public HttpURLConnection getSingleConnection(){
     return conn;
 }
 

}

Using cookies In my multipart Requset Runnable

            DefaultHttpClient client = new DefaultHttpClient();
 
     HttpPost post = new HttpPost(requestUrl);
     HttpResponse resp;
     post.setEntity(reqEntity);
 
     MyApplication app = (MyApplication) mContext
             .getApplicationContext();
 
     try {
     resp = client.execute(post,app.localContext);
