Android Back Button and Progress Dialog

Question

I have an AsyncTask that shows a progressDialog whilst working (it calls runOnUiThread from within doInBackground to show the progress dialog).

javano... I tested your scenario using standard techniques, asyncTask and ProgressDialog. In my test, when the progressDialog is showing and i hit back, the progressdialog is dismissed and the background thread continues to run. I do not know why you need to call runOnUiThread.

SO:

show the progressDialog in onPreExecute place the long running task in doInBackground dismiss the progressDialog in onPostExecute pass the input parameters to your long running task as in:

new MyAsynch().execute(password,inString);

cancel() the asynchTask and progressDialog in onPause

protected void onPause() {
    super.onPause();
    if (asynch != null) {asynch.cancel(true);}
    if (progress != null){progress.cancel();}
}

I have some code here.
