Question

I wrote some code that activity starts a service to get some text from URL, after the service done I want to get this parameters to activity back.

My code looks like this:

public class splash extends AsyncTask<String, Void, String> {

  private Context context; 
  private ProgressDialog Dialog; 
  protected config app;

  public splash(Context context){
      this.context=context;
      Dialog = new ProgressDialog(context);
  }

  protected String doInBackground(String... params) {
      //starts service number activite
      Intent serviceIntent = new Intent();
      serviceIntent.setAction("services.conServise");
      context.startService(serviceIntent);

I dont want to use global parameters and not a singleton

If you want to call the Service from your Activity, what you want is a bound service. It will bind your service to a variable, and you will be able to use that in the Activity.
