Hi,
I understood what you were trying to say. Here's what I;'m doing now:
class ConnectionsListAddScreen extends Activity{
public void onCreate(Bundle savedInstState){
super.onCreate(savedInstState);
//here on particular button click
new ConnReqSenderAsyncTask().execute();
}
protected Dialog onCreateDialog(int id) {
Dialog dialog = new Dialog(ConnectionsListAddScreen.this);
switch(id){
case Constants.LOGIN_DIALOG: ProgressDialog pg = new
ProgressDialog(ConnectionsListAddScreen.this);
pg.setMessage(//some
string);
pg.setCancelable(true);
dialog = pg;
break;
default: return super.onCreateDialog(id);
}
return dialog;
}
}
private class ConnReqSenderAsyncTask extends
AsyncTask<Void,Void,Void>{
protected Void doInBackground(Void... params) {
//send request to server
return null;
}
protected void onPreExecute() {
super.onPreExecute();
showDialog(Constants.LOGIN_DIALOG);
}
protected void onPostExecute(Void result) {
super.onPostExecute(result);
dismissDialog(Constants.LOGIN_DIALOG);
}
}
If the above is right. Then the problem is on Orientation Change it
throws below exception:
FATAL EXCEPTION: main
java.lang.IllegalArgumentException: no dialog with id 5 was ever shown

Since we are using showDialog(...) and onCreateDialog(...) for
ProgressDialog display, then shouldn't Android keep a reference of
same on orientation change. Can you let me know if there are any
mistakes in my code or solution to my problem asap.
