Convert AsyncTask to RxAndroid

Question

I have the following method to post response to UI using otto and AsyncTask.

private static void onGetLatestStoryCollectionSuccess(final StoryColle         


        

Answer 1

Don't use .create() but use .defer()

Observable observable = Observable.defer(new Func0>() {
  @Override public Observable call() {

    File file = downloadFile();

    return Observable.just(file);
  }
});
