private int result = Activity.RESULT_CANCELED;
public String s = "";

public DownloadService() {
super("DownloadService");
}

// Will be called asynchronously be Android
@Override
protected void onHandleIntent(Intent intent) {
Uri data = intent.getData();
String urlPath = intent.getStringExtra("urlpath");

InputStream stream = null;
//FileOutputStream fos = null;
try {

  URL url = new URL(urlPath);
  stream = url.openConnection().getInputStream();
  InputStreamReader reader = new InputStreamReader(stream);
  //fos = new FileOutputStream(output.getPath());
  int next = -1;

  while ((next = reader.read()) != -1) {

As you have append your inputStream from urlPath to "s"

You can access your "s" from your MainActivity using::

String data=new DownloadService().s;

just instantiate IntentService and access it's parameter with the help of period on the instantiated object.
