Voici ApiInterface.Java
public interface ApiInterface {
@GET("bills/")
Call<SponsorsResult> getListOfSponsors(@Query("bill_id") String billId , @Query("session") String session, @Query("fields") String field);
}
Et voici l'appel de la méthode et de la réponse:
ApiInterface apiService = ApiClient.getClient().create(ApiInterface.class);
Call<SponsorsResult> call = apiService.getListOfSponsors(AppConstants.Assembly_BILL_ID,AppConstants.SESSION,AppConstants.FIELD);
call.enqueue(new Callback<SponsorsResult>() {
@Override
public void onResponse(Call<SponsorsResult> call, Response<SponsorsResult> response) {
Log.d(TAG,"Number :"+response.raw());
List<Sponsor> sponsors = response.body().getSponsors();
Log.d(TAG,"Number of sponsors :"+ sponsors.size());
}
@Override
public void onFailure(Call<SponsorsResult> call, Throwable t) {
t.printStackTrace();
}
});
À partir de maintenant, cela échoue et voici la sortie de logcat:
com.google.gson.JsonSyntaxException: Java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 2 path $

Vous pouvez créer automatiquement des classes POJO à partir de la réponse json en utilisant ce lien -> jsonschema2pojo
Tout ce que vous avez à faire est de coller la réponse JSON dans la zone d'édition indiquée.
- Sélectionnez la langue cible en Java,
- Type de source en JSON
- Style d'annotation en Gson
- et cocher Utiliser les types primitifs, inclure les getters et les setters, autoriser des propriétés supplémentaires
Créez ci-dessous la classe dans votre package de modèle:

}
public void setId(String id) {
