Я довольно новичок в Google Maps & Stuff.Я делаю свой последний проект для степени и сталкиваюсь с этой проблемой.Я пытаюсь получить ответ от Places Api, я следовал Официальным документам, чтобы создать URL, но после всей борьбы я не могу получить результат от Google.Я использую Retrofit2 для получения результата.
Я изменил свой URL, изменив Радиус.Изменяя ключ API с ключом браузера (нашел ссылку, предложившую это), ни одно из изменений не вернуло результата.Мое текущее местоположение на карте работает нормально.Помощь будет по достоинству оценена.Спасибо
Вот мой API Retrofit:
public interface GoogleApiService {
@Headers("Content-Type: application/json")
@GET
Call<Places> getNearByPlaces(@Url String url);
}
RetrofitClient:
public class RetrofitClient {
private static Retrofit retrofit = null;
public static Retrofit getClient(String baseUrl)
{
if (retrofit == null)
{
retrofit = new Retrofit.Builder()
.baseUrl(baseUrl)
.addConverterFactory(GsonConverterFactory.create())
.build();
}
return retrofit;
}
}
