Determining which activity is calling AsyncTask

Is there a way to find out which activity is calling AsyncTask? I have two activities which are calling it and I want to do different stuff in onPostExecute(), depending on which activity is calling it.

Something like that:

protected void onPostExecute(String result) {
    //do some stuff with result
    if (callingActivity == mainActivity) {
        //do something
    } else {
        //do something else
    }
}

Just have your Activities subclass your CommonAsyncTask, overriding onPostExecute():

new CommonAsyncTask() {
  @Override
  protected void onPostExecute(String result) {
    // Execute the common code in `CommonAsyncTask`
    super.onPostExecute(result);
    // Now execute the code unique to this activity
  }
};

We always have instanceof for the rescue. Capture the callingActivity while creating AsyncTask and use it in onPostExecute.

For example,

There are two Activities ActivityA and ActivityB. You can check in onPostExecute like 

class AsyncTask<..,..,..> {

  private Activity a;

  public AsyncTask(Activity a) {
    this.a = a;
  }

  protected void onPostExecute(String result) {
    //do some stuff with result
    if (a instanceof ActivityA) {
        //do something
    } else if (a instanceof ActivityB) {
        //do something else
    }
  } 
}
