how to create retrofit object.

public class ApiClient {
    public static final String BASE_URL = "Your Base URL";
    private static Retrofit retrofit = null;

    public static Retrofit getClient() {

        if (retrofit == null) {

            /*HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
            interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);*/

            OkHttpClient client = new OkHttpClient.Builder()
                    //.addInterceptor(interceptor)
                    .protocols(Arrays.asList(Protocol.HTTP_2, Protocol.HTTP_1_1, Protocol.SPDY_3))
                    .connectTimeout(20, TimeUnit.SECONDS)
                    .readTimeout(20000, TimeUnit.SECONDS)
                    .writeTimeout(10000, TimeUnit.SECONDS)
                    .retryOnConnectionFailure(true)
                    .build();

            Gson gson = new GsonBuilder()
                    .setLenient()
                    .create();

            retrofit = new Retrofit.Builder()
                    .baseUrl(BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create(gson))
                    .client(client)
                    .build();
        }

        return retrofit;
    }
}
