Android Can'；无法通过改装从服务器获取数据

我有以下代码：

private static final String Tag = "DataUtil";

    static List<Film> generateFilms(){
        Log.i(Tag, "In generate films");
        List  <Film> films = new ArrayList<>();
        String BaseUrl = "http://www.omdbapi.com/?apikey=956febbc&";
        Retrofit.Builder builder = new Retrofit.Builder().baseUrl(BaseUrl)
                .addConverterFactory(GsonConverterFactory.create());
        OkHttpClient.Builder httpClient = new OkHttpClient.Builder()
                .connectTimeout(10, TimeUnit.SECONDS)
                .writeTimeout(10, TimeUnit.SECONDS)
                .readTimeout(30, TimeUnit.SECONDS);
        Retrofit retrofit = builder.build();
        APIService apiService  = retrofit.create(APIService.class);
        final Call<List<Film>> filmsCall = apiService.getFilms();
        filmsCall.enqueue(new Callback<List<Film>>() {
            @Override
            public void onResponse(Call<List<Film>> call, Response<List<Film>> response) {
                if (response.isSuccessful()){
                    Log.i(Tag, response.body().get(0).getTitle());
                }
                else {
                    Log.i(Tag, "Response code: "+response.code());
                }
            }

            @Override
            public void onFailure(Call<List<Film>> call, Throwable t) {
                Log.i(getClass().getSimpleName(), "Error: "+t);
            }
        });

        return films;
    }

获取使用查询

@GET(".")
Call<Film> getFilms(@Query("apikey") String apikey, @Query("t") String t);

@GET（“.”）
调用getFilms（@Query（“apikey”）字符串apikey，@Query（“t”）字符串t）；

请求数据

apiService.getFilms（“956febbc”，“蝙蝠侠”）

根据我所知，改装中的基本url应该以斜杠结尾。尝试使用类似“omdbapi.com/”的基本url，并将api键移动到接口@GET（“？apikey=956febbc&t=batman”）。希望这能有所帮助。@DanielSpiess不幸的是，当我以

String BaseUrl=”的方式进行更改时http://www.omdbapi.com/";和在接口“@GET”（“？apikey=956febbc&t=batman”）中没有任何更改可能是
I/: Error: java.net.UnknownServiceException: CLEARTEXT communication to www.omdbapi.com not permitted by network security policy

String BaseUrl = "http://www.omdbapi.com";

@GET(".")
Call<Film> getFilms(@Query("apikey") String apikey, @Query("t") String t);
