Try this once.... 

                for (int i = 0; i < response.length(); i++) {
                try {

                    JSONObject obj = response.getJSONObject("_embedded");
                     Iterator iterator = Obj.keys();

                    //while(iterator.hasNext()){
                    String key = (String) iterator.next();
                    JSONObject issue = Obj.getJSONObject(key);
                    JSONArray array = obj.getJSONArray("events");
                    JSONObject obj2 = array.getJSONObject(i);
                    JSONObject obj = response.getJSONObject("_embedded");
                    JSONArray array1 = obj2.getJSONArray("venues");
                    JSONObject obj3 = array1.getJSONObject(0);
                    JSONObject obj4 = obj3.getJSONObject("city");
                    String key1 = (String) iterator.next();
                    JSONObject issue1 = Obj.getJSONObject(key1);
                    Event event = new Event();
                    event.setName(obj2.getString("name"));


                    // adding movie to movies array
                    eventList.add(event);

                } catch (JSONException e) {
                    e.printStackTrace();
                }

Try this code to get cities

                  for (int i = 0; i < response.length(); i++) {
                    try {

                        JSONObject obj = response.getJSONObject("_embedded");
                        JSONArray array = obj.getJSONArray("events");
                        JSONObject obj2 = array.getJSONObject(i);
                        JSONObject obj = response.getJSONObject("_embedded");
                        JSONArray array1 = obj2.getJSONArray("venues");
                        JSONObject obj3 = array1.getJSONObject(0);
                        JSONObject obj4 = obj3.getJSONObject("city");
                        Event event = new Event();
                        event.setName(obj2.getString("name"));


                        // adding movie to movies array
                        eventList.add(event);

                    } catch (JSONException e) {
                        e.printStackTrace();
                    }

Also I recommend using GSON for parsing JSON

You can convert your json data to pojo model class. It will help you to easily get values. here is example of your model pojo class

public class ItemOption {
@SerializedName("embeded")
@Expose
private Embeded embeded;public Embeded getEmbeded() {
    return embeded;
}

public void setEmbeded(Embeded embeded) {
    this.embeded = embeded;
}

public class City {

    @SerializedName("name")
    @Expose
    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

public class Embeded {

    @SerializedName("events")
    @Expose
    private List<Event> events = null;

    public List<Event> getEvents() {
        return events;
    }

    public void setEvents(List<Event> events) {
        this.events = events;
    }

}

public class Embeded_ {

    @SerializedName("venue")
    @Expose
    private List<Venue> venue = null;

    public List<Venue> getVenue() {
        return venue;
    }

    public void setVenue(List<Venue> venue) {
        this.venue = venue;
    }

}

public class Event {

    @SerializedName("embeded")
    @Expose
    private Embeded_ embeded;

    public Embeded_ getEmbeded() {
        return embeded;
    }

    public void setEmbeded(Embeded_ embeded) {
        this.embeded = embeded;
    }

}


public class Venue {

    @SerializedName("city")
    @Expose
    private City city;

    public City getCity() {
        return city;
    }

    public void setCity(City city) {
        this.city = city;
    }

}}

and then 

itemOption.getEmbeded().getEvents().get(0).getEmbeded().getVenue().get(0).getCity();

Please check this out. 

JSONObject object = new JSONObject(response.toString());
JSONObject embedded = object.getJSONObject("_embedded");
JSONArray eventsArray = embedded.getJSONArray("events");

for(int i = 0;i<eventsArray.length();i++){
  JSONObject event = eventsArray.getJSONObject(i);
  // Parse data from this event object
}

Hope this helps.
