Thanks for the response. I tried switching to AsyncTask and have had great
success but I am now stuck on what appears to be a minor point. Yet I can
see my error. Attached is a snippet:
private class LoadSchedules extends AsyncTask<Object, Object, Object> {
@Override
protected void onPreExecute () {
mProgressText.setText("Let's begin");
}
@Override
protected Object doInBackground(Object... arg0) {
publishProgress("agencies");
Load_Table("agencies", "agency.txt",AgencyFlds,
mAgencies);
publishProgress("calendar");
Load_Table("calendar","calendar.txt",CalendarFlds,
mCalendar);
publishProgress("routes");
Load_Table("routes", "routes.txt", RouteFlds, mRoutes);
return true;
}
@Override
protected void onProgressUpdate(String... tablename){
mProgressText.setText("Loading " + tablename);
}
@Override
protected void onPostExecute (Object b) {
mProgressText.setText("Game over");
}
}
________________________________________________________________________
The compiler keeps complaining that my onProgressUpdate method must
"Override or implement a supertype method". When I remove the @Override, the
compiler is happy. However when I run the app, I do not get the progress
updates. I have tried various combinations of coding this method but with no
success. I am sure it is something simple. Can someone please save me some
time?
TIA

You're executing long-running processes in the main thread (onCreate) which
don't return control to the main (UI) thread to allow it to show your
progress dialog until it's too late. Look into AsyncTask.
Also, the "mCtx = this;" is rather pointless. You're keeping a reference to
yourself - which is exactly what "this" is.
