Retrofit: expected BEGIN_OBJECT but BEGIN_ARRAY
Sorry for another question about this error, but everything I read was helpless for me.
I am using Retrofit Library and GSON to parse JSON responses. I got this error:
E/RETROFIT ERROR﹕ com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 2 path $
JSON response:
[
{
"route_id": 16,
"typeofmovement_name": "Type name",
"route_description": "Just default description and no more",
"route_name": "Default name",
"route_img_url": "place reserved for url",
"themes": [
"Theme name one",
"Theme name two"
],
"routeparts": [
{
"rp_id": 32,
"part_id": 1,
"rp_start_latitude": "59.935353200891576",
"rp_start_longitude": "30.31521778553724",
"rp_end_latitude": "59.93948523234933",
"rp_end_longitude": "30.314136184751987",
"rp_description": "Default Description",
"rp_title": "Default Title"
},
{
"rp_id": 33,
"part_id": 2,
"rp_start_latitude": "59.93948523234933",
"rp_start_longitude": "30.314136184751987",
"rp_end_latitude": "59.940330654891774",
"rp_end_longitude": "30.328612737357613",
"rp_description": "Default Description",
"rp_title": "Default Title"
},
{
"rp_id": 34,
"part_id": 3,
"rp_start_latitude": "59.940330654891774",
"rp_start_longitude": "30.328612737357613",
"rp_end_latitude": "59.934541749310746",
"rp_end_longitude": "30.33052649348974",
"rp_description": "Default Description",
"rp_title": "Default Title"
}
]
}
]
The class I am using to parse GSON
public class Route {
@SerializedName("route_id") private int routeId;
@SerializedName("typeofmovement_name") private String typeOfMove;
@SerializedName("route_description") private String routeDescription;
@SerializedName("route_name") private String routeTitle;
@SerializedName("route_img_url") private String imgUrl;
@SerializedName("themes") private String[] themes;
private List<Routeparts> routeparts;
Route() {
this.routeparts = new ArrayList<>();
}
class Routeparts {
int rp_id;
int part_id;
String rp_start_latitude;
String rp_start_longitude;
String rp_end_latitude;
String rp_end_longitude;
String rp_description;
String rp_title;
}
There is a Retrofit API
@GET("/routes/{route_id}")
void getRouteInfo(@Path("route_id") String routeId, Callback<Route> callback);
PS Sorry for any possible grammar errors.

You have a Retrofit function that should be something like
@GET("/Routes") void getRoutes(Callback<List<Route>> routesCallback);
And your call should be something like
RetrofitService.getRoutes(new Callback<List<Route>>() {
@Override public void success(List<Route> routes, Response response) {
//success
}
@Override public void failure(RetrofitError error) {
//error
}
});
If you really expect one route, you will have to change the server code.
