I've already read this question Google Map Direction Api using Retrofit I want to get the time and the distance so I've created these model classes
Distance.java
public class Distance{
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public int getValue() {
return value;
}
public void setValue(int value) {
this.value = value;
}
@SerializedName("text")
private String text;
@SerializedName("value")
private int value;
}
Duration.java
public class Duration{
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public int getValue() {
return value;
}
public void setValue(int value) {
this.value = value;
}
@SerializedName("text")
private String text;
@SerializedName("value")
private int value;
}
Legs.java
public class Legs{
private Distance distance;
private Duration duration;
public Distance getDistance() {
return distance;
}
public void setDistance(Distance distance) {
this.distance = distance;
}
public Duration getDuration() {
return duration;
}
public void setDuration(Duration duration) {
this.duration = duration;
}
}
Route.java
public class Route{
@SerializedName("legs")
private List<Legs> legses;
public List<Legs> getLegses() {
return legses;
}
public void setLegses(List<Legs> legses) {
this.legses = legses;
}
}
The interface:
public interface MyApiRequestInterface {
@GET("maps/api/directions/json")
public void getJson(@Query("origin") String origin, @Query("destination") String destination, Callback<DirectionResults> callback);
}
and in the fragment:
String base_url = "http://maps.googleapis.com/";
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(base_url)
.build();
MyApiRequestInterface reqinterface = retrofit.create(MyApiRequestInterface.class);
String origin = "41.2198254,16.3076254";
String dest = "41.2199,16.3062";
reqinterface.getJson(origin,dest, new Callback<DirectionResults>() {
@Override
public void onResponse(Call<DirectionResults> call, Response<DirectionResults> response) {
Log.d("CallBack", " response is " + response);
}
@Override
public void onFailure(Call<DirectionResults> call, Throwable t) {
Log.d("CallBack", " Throwable is " +t);
}
});
Running the app I've the following error:
java.lang.IllegalArgumentException: Service methods cannot return void.

--EDIT--
I create the interface in this way:
public interface Api {
@GET("maps/api/directions/json")
Call<DirectionResults> getJson(@Query("origin") String origin, @Query("destination") String destination);
}
in the fragment:
String base_url = "http://maps.googleapis.com/";
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(base_url)
.addConverterFactory(GsonConverterFactory.create())
.build();
String origin = "41.2198254,16.3076254";
String dest = "41.2199,16.3062";
Api service = retrofit.create(Api.class);
service.getJson(origin,dest).enqueue(new Callback<DirectionResults>() {
@Override
public void onResponse(Call<DirectionResults> call, Response<DirectionResults> response) {
Log.d("CallBack", " response is " + response);
Route routeA = response.body().getRoutes().get(0);
Legs legs =routeA.getLegses().get(0);
}
@Override
public void onFailure(Call<DirectionResults> call, Throwable t) {
Log.d("CallBack", " Throwable is " +t);
}
});
Now works! In the example above I used a fixed origin and destination, but if I want to iterate an arraylist, calculate the distance of each items and pass the data to the adapter, what can I do?
