androidの特定のバージョンでレトロフィットが機能しない

Android 4.3を実行しているエミュレータでRetrofitに問題があり、デバイスがAndroid 4.4.2にある場合、同じコードが= Android 7.1.1

getリクエストを実行しようとするたびに、タイムアウト例外が発生します。

コードは以下です

public interface Api {
    String BASE_URL = "https://jsonplaceholder.typicode.com/";

    @GET("posts")
    Call<ArrayList<Post>> getPosts();
}

そしてAPIへの呼び出し

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl(Api.BASE_URL)
        .addConverterFactory(GsonConverterFactory.create())
        .build();

Api api = retrofit.create(Api.class);
Call<ArrayList<Post>> call = api.getPostes();
Log.i("RequestUrl", call.request().url().toString());
call.enqueue(new Callback<ArrayList<Post>>() {
    @Override
    public void onResponse(Call<ArrayList<Post>> call, Response<ArrayList<Post>> response) {
        mPostsList.setValue(response.body());
    }

    @Override
    public void onFailure(Call<ArrayList<Post>> call, Throwable t) {
        Log.e("Posts", "Error occurred", t);
    }
});

21より前のAndroidにはSSLが欠落していて、レトロフィットが機能しません。 Googleサービスを使用すると、HTTPリクエストが機能するようになった後にデバイスプロトコルを更新できます

    //compile 'com.google.Android.gms:play-services-base:11.0.0'
     //remember to add the library in your dependencies

        //compile 'com.google.Android.gms:play-services-base:$currentVersion'

        ProviderInstaller.installIfNeededAsync(this, new ProviderInstallListener() {

            @Override

            public void onProviderInstalled() {

                //Do your http request here

            }


            @Override

            public void onProviderInstallFailed(int errorCode, Intent recoveryIntent) {

                //sad face :C is sad

            }

        });
