Why is it not possible to loop a call execute to get multiple responses inside my IntentService via Retrofit?
Please see my code:
public class UpdateAgendaService extends IntentService {
public static final int STATUS_RUNNING = 0;
public static final int STATUS_FINISHED = 1;
public static final int STATUS_ERROR = 2;
private Agenda agenda;
public UpdateAgendaService() {
super(UpdateAgendaService.class.getName());
}
@Override
protected void onHandleIntent(Intent intent) {
final ResultReceiver receiver = intent.getParcelableExtra("receiver");
String[] dateWeek = intent.getStringArrayExtra("dateWeek");
if (dateWeek != null) {
receiver.send(STATUS_RUNNING, Bundle.EMPTY);
Bundle bundle = new Bundle();
try {
//Why is this not possible?
List<Agenda> agendaList = getAgendaList(dateWeek);
receiver.send(STATUS_FINISHED, bundle);
}
} catch (Exception e) {
/* Sending error message back to activity */
bundle.putString(Intent.EXTRA_TEXT, e.toString());
receiver.send(STATUS_ERROR, bundle);
}
}
Log.d(Utilities.TAG, "Service Stopping!");
this.stopSelf();
}
private List<Agenda> getAgendaList(String[] upcomingWeekdates){
List<Agenda> agendaList = null;
for (int i = 0; i < upcomingWeekdates.length; i++) {
String weekDay = upcomingWeekdates[i];
agendaList.add(getAgenda(weekDay));
}
return agendaList;
}
private Agenda getAgenda(String date) {
Agenda agenda = null;
ApiService apiService = new QardioApi().getApiService();
Call<Agenda> call = apiService.getAgenda(date);
try {
agenda = call.execute().body();
} catch (IOException e) {
e.printStackTrace();
}
return agenda;
}
}
So the situation is that I have an API which has a url: http//:myapi.com/[date] which when called via retrofit gives me a JSON response of the Agenda(Events) for that specific day. What I want to do is to show the agenda(events) for the upcoming week, that is why I did it via loop given a String array of dates for the upcoming week. Imagine kind of like the Eventbrite app.
What I am doing wrong? I read somewhere that I should do this via JobQueue/Eventbus, should I be doing that? But I am a bit hesitant because I don't want to be using any more third party libraries. However, if that is the last case scenario I will probably just go with that then.
