Lifecycle Aware Data Loading with Android Architecture Components
Ian Lake

What is the recommended approach to reload the data backed by LiveData? App to fetch news feed would have cached data in its view model. Users would want to pull down to refresh the view. In this case, i would want to ignore the catch and go to the actual data source (Retrofit etc). I’m guessing, it would have to be a custom LiveData and expose a refresh API?

public class JsonLiveData extends LiveData<List<String>> {
private final Context context;
private final FileObserver fileObserver;
  public JsonLiveData(Context context) {
  public void refresh() {
One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
