public class Calculate extends AsyncTask<Void, Integer, Integer> {
@Override
protected void onPreExecute() {
super.onPreExecute();
}
@Override
protected Integer doInBackground(Void... arg0) {
int a = 1;
int b = 2
return a+b;

@Override
protected void onPostExecute(Integer result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
}
}
my app use asynctask class (below), and a function to call this class, my question is how to know when this class is finished ? every time i check, its always Running !
In your onPostExecute(...)
method, you could simply call a method in your caller Activity
which would set a boolean terminated_activity
to true
. You can do this in several ways, most probably the easiest ones are Intents
combined with a Handler
, or a local BroadcastReceiver
.
onPostExecute(Result), invoked on the UI thread after the background computation finishes. The result of the background computation is passed to this step as a parameter.
