Hi
I have a problem, I have only used asynctask for "singel return items before.

But now I want to the following:

send some "pree setings in a constructor."
then in a asynktask so put result in a String array..
and sent it to the UI..

but I dont know how to declare this.. :-(

class ASYNKsparaNedMedGeo extends AsyncTask<String, String, String[]> {
some strings...

public ASYNKsparaNedMedGeo("some in-variabels..") {
this.skaGatuadressUppdatreras = skaGatuadressUppdatreras;
...
// TODO Auto-generated constructor stub
}

@Override
protected void onPreExecute() {
super.onPreExecute();
// Shows Progress Bar Dialog and then call doInBackground method
showDialog(progress_bar_type);
}

@Override
protected String[] doInBackground(String... f_url) {
....
siteArray = getSiteInfoFromSitesListArrayNew(elementval);
return null;

protected void onProgressUpdate(String... progress) {
// Set progress percentage
prgDialog.setProgress(Integer.parseInt(progress[0]));
}

protected String[] onPostExecute(String file_url ) {

dismissDialog(progress_bar_type);
Toast.makeText(getApplicationContext(), "siteInfo : " + siteInfo, Toast.LENGTH_LONG).show();
return siteInfo;
}

}

Is there any tutorials?

 
It is sorta covered in the JavaRanch Style Guide.
