Android Service Choice

Question

I'm porting an application from C# to Android and I need some help to decide which service type i'd need to use on Android to achieve the same result.

Currently theres 2 seperate application. An updater and a client. The updater polls the webserver for updates every 5 seconds. Whenever an update is available it downloads it then warns the client that there's new content available.

The client then displays the content onscreen.

Note: This software will be run on a android player and its sole purpose is to run these 2 applications. Nothing more. There will be no user interaction with it.

So my question is what service would I need to use for this?

Kind Regards, Niek

You can check the following links http://developer.android.com/reference/android/app/Service.html http://developer.android.com/guide/components/services.html http://www.vogella.com/articles/AndroidServices/article.html

You can add a thread which will download code after every 5 seconds. Here is the code

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.util.Log;
import android.widget.Toast;

public class MyService extends Service {

   String tag="TestService";
   @Override
   public void onCreate() {
       super.onCreate();
       Toast.makeText(this, "Service created...", Toast.LENGTH_LONG).show();      
       Log.i(tag, "Service created...");
   }

   @Override
   public void onStart(Intent intent, int startId) {      
       super.onStart(intent, startId);  
       Log.i(tag, "Service started...");
       fetchData();
   }

   public void fetchData()
   {
   new Thread(new Runnable()
                    {

                        @Override
                        public void run()
                            {
                            while(true)
                            {
                                final String strRes = downloadXML("http://uri.com");
                                runOnUiThread(new Runnable()
                                    {

                                        @Override
                                        public void run()
                                            {
                                                //do whatever once download complete
                                            }
                                    });
                                    try{
                                    Thread.sleep(5000);
                                    }catch(Exception ee){}
                            }
                            }
                    }).start();
   }
   @Override
   public void onDestroy() {
       super.onDestroy();
       Toast.makeText(this, "Service destroyed...", Toast.LENGTH_LONG).show();
   }

   @Override
   public IBinder onBind(Intent intent) {
       return null;
   }
}
