Answer 1

What I've done finally is going to my API project and create a CustomSerializer

public class CustomDateSerializer extends JsonSerializer {  

    @Override
    public void serialize(Date t, JsonGenerator jg, SerializerProvider sp) throws IOException, JsonProcessingException {
        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
        String formattedDate = formatter.format(t);

        jg.writeString(formattedDate);
    }
}

that return the format yyyy-MM-dd and I annotated date fields with

@JsonSerialize(using = CustomDateSerializer.class)

in my Android application I created Gson object as

            Reader reader = new InputStreamReader(content);

            GsonBuilder gsonBuilder = new GsonBuilder();
            gsonBuilder.setDateFormat("yyyy-MM-dd");
            Gson gson = gsonBuilder.create();
            appels = Arrays.asList(gson.fromJson(reader, Appel[].class));
            content.close();

and it works for now .. thanks for your help I appreciate it
