I am trying to get a response using Retrofit and display images from a url within the json response. I don't know how to debug for Retrofit. I get into the "failure" block and see my "Fail" toast. Here is some code:
Main Activity:
public class TheMovieDbActivity extends Activity {
private GridView gridView;
private List<MovieModel> movieModelsList;
private String ENDPOINT_URL = "https://api.themoviedb.org";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.movie_db_activity);
gridView = (GridView) findViewById(R.id.gridView);
final RestAdapter restadapter = new RestAdapter.Builder().setEndpoint(ENDPOINT_URL).build();
apiLocation apiLocation = restadapter.create(apiLocation.class);
apiLocation.getData(new Callback<List<MovieModel>>() {
@Override
public void success(List<MovieModel> movieModels, Response response) {
movieModelsList = movieModels;
MoviesGridViewAdapter adapter = new MoviesGridViewAdapter(getApplicationContext(), R.layout.movie_gridview_item, movieModelsList);
gridView.setAdapter(adapter);
}
@Override
public void failure(RetrofitError error) {
Toast.makeText(getApplicationContext(), "Failed", Toast.LENGTH_SHORT).show();
}
});
}
}
My Adapter:
public class MoviesGridViewAdapter extends ArrayAdapter<MovieModel> {
String url="http://services.hanselandpetal.com/photos/";
private Context context;
private List<MovieModel> movieModelList;
LayoutInflater inflater;
public MoviesGridViewAdapter(Context context, int resource, List<MovieModel> objects) {
super(context,resource,objects);
this.context = context;
this.movieModelList = objects;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.movie_gridview_item, parent, false);
MovieModel movieModel = movieModelList.get(position);
ImageView img = (ImageView) view.findViewById(R.id.grid_item_image);
Picasso.with(getContext()).load(url+movieModel.getPosterPath()).resize(100, 100).into(img);
return view;
}
}
And my interface:
public interface apiLocation {
@GET("/3/movie/popular?my api key")
void getData(Callback<List<MovieModel>> response);
}
POJO:
public class MovieModel {

You are getting an object, but expecting an array. You need a POJO model for the response of the popular endpoint. Based on the docs, it looks something like this --
class MovieDBResponse {
int page;
List<MovieModel> results;
int total_pages;
int total_results;
}
then change your interface to --
public interface apiLocation {
@GET("/3/movie/popular?my api key")
void getData(Callback<List<MovieDBResponse>> response);
}
Update your adapter to extract results to use as your list of MovieModels
