java - DefaultHttpClient Depricated Android Studio 2.2.2 -
after following few guides on how data , send data database on local server using apache , mysqlli , error occurred saying code deprecated. after looking guides on deprecation found out of them outdated. here codes of manifest, parser , , gradle file module(by order):

[update] highly recommend use okhttp instead of org.apache.http. way faster (coding time) , simpler maintain/code.
get request
okhttpclient client = new okhttpclient(); string run(string url) throws ioexception { request request = new request.builder() .url(url) .build(); response response = client.newcall(request).execute(); return response.body().string(); } post request
public static final mediatype json = mediatype.parse("application/json; charset=utf-8"); okhttpclient client = new okhttpclient(); string post(string url, string json) throws ioexception { requestbody body = requestbody.create(json, json); request request = new request.builder() .url(url) .post(body) .build(); response response = client.newcall(request).execute(); return response.body().string(); } have'nt find better far!
just add following dependency
compile 'com.squareup.okhttp3:okhttp:3.4.2' the full code.
import android.content.contentvalues; import android.util.log; import org.json.jsonexception; import org.json.jsonobject; import java.io.ioexception; import okhttp3.mediatype; import okhttp3.okhttpclient; import okhttp3.request; import okhttp3.requestbody; import okhttp3.response; public class jsonparser { static jsonobject jobj = null; static string json = ""; // constructor public jsonparser() { } // function json url // making http post or mehtod public static jsonobject makehttprequest(string url, string method, contentvalues params) { // making http request try { final okhttpclient client = new okhttpclient(); request request; // check request method if (method.equals("post")) { // request method post final mediatype json = mediatype.parse("application/json; charset=utf-8"); final requestbody body = requestbody.create(json, params.tostring()); request = new request.builder() .url(url) .post(body) .build(); } else if (method.equals("get")) { // request method request = new request.builder() .url(url) .build(); } final response response = client.newcall(request).execute(); json = response.body().string(); } catch (ioexception e) { e.printstacktrace(); } // try parse string json object try { jobj = new jsonobject(json); } catch (jsonexception e ){ log.e("json parser", "error parsing data " + e.tostring()); } // return json string return jobj; } }
