Best practice for getting json from url in api 23

Question

I use compileSdk 23version 23 with library support.

I used the httplegacy library (I copied it to the app / libs folder from androidSdk / android-23 / optional / org.apache.http.legacy.jar) and in gradle I put:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

To download this library.

In my Connection class, I have a way to load an instance DefaultHttpClientlike this:

private static HttpClient getClient(){
    HttpParams httpParameters = new BasicHttpParams();
    int timeoutConnection = 3000;
    HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
    int timeoutSocket = 3000;
    HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);

    DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters);

    return httpClient;
}

But Android Studio says all classes apache.httpare out of date.

What can I use to follow best practices?

, . :

HTTP- Apache. Android 2.3 ( API 9) , HttpURLConnection. API

HttpURLConnection:

   URL url = new URL("http://www.android.com/");
   HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
   try {
     InputStream in = new BufferedInputStream(urlConnection.getInputStream());
     readStream(in);
    finally {
     urlConnection.disconnect();
   }
 }

- . Fuel Kotlin ( Java) Http-request Java-. HttpURLConnection .

Http-Request:

HttpRequest request = HttpRequest.get("http://google.com");
String body = request.body();
int code = request.code();

Fuel:

Fuel.get("http://httpbin.org/get", params).responseString(new Handler<String>() {
    @Override
    public void failure(Request request, Response response, FuelError error) {
        //do something when it is failure
    }

    @Override
    public void success(Request request, Response response, String data) {
        //do something when it is successful
    }
});
