Get a link to work from the service

I need to get a link to the main activity from the service.

This is my design:

MainActivity.java

public class MainActivity extends Activity{
private Intent myIntent;
onCreate(){
 myIntent=new Intent(MainActivity.this, MyService.class);

 btnStart.setOnClickListener(new OnClickListener(){
  public void onClick(View V){
   startService(myIntent);
   });
}}

MyService.java

class MyService extends Service{

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

 onCreate(){
 //Here I need to have a MainActivity reference
 //to pass it to another object
 }
}

How can i do this?

[EDIT]

Thanks everyone for the answers! This application is a web server that currently only works with streams, and I want to use the service instead so that it also works in the background. The problem is that I have a class that is responsible for getting the page from resources, and for this operation I need to use this method:

InputStream iS =myActivity.getAssets().open("www/"+filename);

At the moment, my project has only one Activity and no services, so I can transfer the main link to the Activity directly from myself:

WebServer ws= new DroidWebServer(8080,this);

So, to make this application work with the service, what should I change in my design?
