I'm trying to send json data to an http url without success (I tried to send same data to an other https with success). I have this settings: config.xml

<access origin="*" />
<allow-intent href="http://*/*" />
<allow-intent href="https://*/*" />

AndroidManifest.xml

android:usesCleartextTraffic="true"

  $.ajax({
    type: "GET",
    url: url,
    dataType: "jsonp",
    jsonp: 'callback',
    crossDomain: true,
    async: true,
    data: {
      id: results.rows.item(i).id,
      bolla: results.rows.item(i).bolla,
      anno: results.rows.item(i).anno,
      magazzino: results.rows.item(i).magazzino,
      articolo: results.rows.item(i).articolo,
      quantita: results.rows.item(i).quantita,
      term: terminale
    },
    success: function (data) {
      console.log(data)
    },
    error: function (xhr, textStatus, err) {
      alert("readyState: " + xhr.readyState);
      alert("responseText: " + xhr.responseText);
      alert("status: " + xhr.status);
      alert("text status: " + textStatus);
      alert("error: " + err);
    }
  });
</script>

If I use json it returns devicereadystate=0 and error if I use jsonp it returns devicereadystate=4 and error 404 (the url is correct if I paste to a browser it works)
