I had this issue where on a screen orientation change, the activity finished before the AsyncTask with the progress dialog completed. I seemed to resolve this by setting the dialog to null onPause()
and then checking this in the AsyncTask before dismissing.
@Override
public void onPause() {
super.onPause();
if ((mDialog != null) && mDialog.isShowing())
mDialog.dismiss();
mDialog = null;
}
… in my AsyncTask:
protected void onPreExecute() {
mDialog = ProgressDialog.show(mContext, "", "Saving changes...",
true);
}
protected void onPostExecute(Object result) {
if ((mDialog != null) && mDialog.isShowing()) {
mDialog.dismiss();
}
}
