Sending a variable to mysql

Sending a variable to mysql - android

I want to send the Id_student variable to MySQL but face to the following exception:

}
});
requestQueue = Volley.newRequestQueue(this);
requestQueue.add(jsonArrayRequest);
}
public void JSON_PARSE_DATA_AFTER_WEBCALL(JSONArray array){
for(int i = 0; i<array.length(); i++) {
GetDataAdapter GetDataAdapter2 = new GetDataAdapter();
JSONObject json = null;
try {
json = array.getJSONObject(i);
GetDataAdapter2.setImageTitleNamee(json.getString(JSON_IMAGE_TITLE_NAME));
GetDataAdapter2.setImageServerUrl(json.getString(JSON_IMAGE_URL));
} catch (JSONException e) {
e.printStackTrace();
}
GetDataAdapter1.add(GetDataAdapter2);
}
recyclerViewadapter = new RecyclerViewAdapter(GetDataAdapter1, this);
recyclerView.setAdapter(recyclerViewadapter);
}
Would you please guide me to solve my problem?

Volley is not pulling Json data from my URL

people so I have a valid URL with JSON data in it, I pull the data with volley but it's not working for some reason, when I change the URL it works. But I need to use this URL with this data in my project. I think the structure of the URL is the problem, but I don't know how to fix it, Please help. Thank you!
The URL I am using is https://zlatnakopacka.mk/api/TopOfferPreview_feed?source=zk
public class TestOne extends AppCompatActivity {
String url = "https://zlatnakopacka.mk/api/TopOfferPreview_feed?source=zk";

adaptor = new PonudiAdapter(getApplicationContext());
recyclerView.setAdapter(adaptor);
ponudis = new ArrayList<>();
getData("1");
switchSve.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

In response you are getting below error.
"javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found."
I found some answers here is reference that will help you.
Trusting all certificates using HttpClient over HTTPS

Replace getData() Method
Write This method -
private void getData() {
// final ProgressDialog progressDialog = new ProgressDialog(this);
// progressDialog.setMessage("Се вчитува...");
// progressDialog.show();
ponudis.clear();
JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(url, new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
try {
for (int i = 0; i < response.length(); i++) {
JSONObject jsonObject = response.getJSONObject(i);
Ponudi ponudi = new Ponudi();
ponudi.setSh_sport_id(jsonObject.getString("sh_sport_id"));
ponudi.setTim1(jsonObject.getString("tim1"));
ponudi.setTim2(jsonObject.getString("tim2"));

Cannot connect to the API using Volley

I am trying to get a JSON request from an API using volley but it didn't seem to work. I did try another dummy API and it works but not for this one. The one I am currently using has headers with key and value. Also, on checking the API on postman, I saw that the JSON format begins with '[' so I am not sure what to put for the JSONObject. Also, I am not sure if I added the header right. I am very new to android and would definitely appreciate it if someone could help me out.

Replace your JsonObjectRequest with:
JsonArrayRequest request = new JsonArrayRequest(url, new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray jsonArray) {
for (int i = 0; i < jsonArray.length(); i++) {....}
}

hi i have an app shows the online streamers from Twitch.tv and the data comes from request i send but i cant parse them this is my code
public ArrayList<Twitch> ParseTwitch(JSONArray object, Context context){
ArrayList<Twitch> chanels = new ArrayList<>();
try {
for (int i = 0;i<object.length();i++){
JSONObject streamObjct = object.getJSONObject(i);
JSONObject chanel = streamObjct.getJSONObject("channel");
JSONObject url= streamObjct.getJSONObject("preview");
final Twitch twitch = new Twitch();
twitch.setName(chanel.getString(CHANEL_NAME));
twitch.setStatus(chanel.getString(CHANEL_STATUS));
twitch.setGame(streamObjct.getString(GAME));
twitch.setLanguage(chanel.getString(BROADCASTER_LANGUAGE));
twitch.setViewrs(streamObjct.getInt(VIEWRS));
String imageUrl = url.getString("medium");
ImageRequest request =new ImageRequest(imageUrl, new Response.Listener<Bitmap>() {
#Override

and this my request

at least can anyone tell me should i work with sqlite Database or not?
where i called TwitchParcer
private void prepareData(String url, final ListView mListView) {

RecyclerView fill it with a Volley request doesn't show results

I'm having a problem with Volley and the RecyclerView.
In the onCreate Method of my Activity, I call a Volley Request to get data from my server. I then pass it to my Adapter as a List.
The thing is that everything is happening so fast when the onCreate method has finished my Volley Request hasn't finished yet, so nothing is displayed on the screen, how can I avoid this?
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity__services__worker);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setTitle("Servicios");
final List services = new ArrayList();
RequestQueue requestQueue = Volley.newRequestQueue(this);
StringRequest stringRequest = new StringRequest(Method.GET, AppConfig.URL_GET_SERVICES_REQUIRED, new Response.Listener<String>(){
#Override
public void onResponse(String response){
try{
JSONArray jsonArray = new JSONArray(response);
for(int i=0; i<jsonArray.length(); i++){
JSONObject jsonObject = jsonArray.getJSONObject(i);
String tag_servicio = jsonObject.getString("contratista");
String servicio = jsonObject.getString("descipcion_del_problema");
String zona = jsonObject.getString("zona");
String money = jsonObject.getString("precio_min");
//Toast.makeText(Activity_Services_Worker.this, tag_servicio+servicio+zona+money, Toast.LENGTH_SHORT).show();
services.add(new Servicios_worker(tag_servicio, servicio, zona, money));
}
}catch (JSONException e){
e.printStackTrace();
}
}
}, new Response.ErrorListener(){
#Override
public void onErrorResponse (VolleyError error){
Log.e(TAG, "Registration Error: " + error.getMessage());
Toast.makeText(Activity_Services_Worker.this, error.getMessage(), Toast.LENGTH_LONG).show();
}
});
requestQueue.add(stringRequest);
recycler = (RecyclerView) findViewById(R.id.servicesAsked_RecyclerView);
recycler.setHasFixedSize(true);
lManager = new LinearLayoutManager(this);
recycler.setLayoutManager(lManager);
adapter = new Adapter_services_required(services);
recycler.setAdapter(adapter);
}

In the add method, which I think is adding an element to the array of elements of the adapter, you should do notifyDatasetChanged() or you can do this:
...
final List services = new ArrayList();
;; CHANGED
recycler = (RecyclerView) findViewById(R.id.servicesAsked_RecyclerView);
recycler.setHasFixedSize(true);
lManager = new LinearLayoutManager(this);
recycler.setLayoutManager(lManager);
adapter = new Adapter_services_required(services);
recycler.setAdapter(adapter);
RequestQueue requestQueue = Volley.newRequestQueue(this);
StringRequest stringRequest = new StringRequest(Method.GET, AppConfig.URL_GET_SERVICES_REQUIRED, new Response.Listener<String>(){
#Override
public void onResponse(String response){
try{
JSONArray jsonArray = new JSONArray(response);
for(int i=0; i<jsonArray.length(); i++){
JSONObject jsonObject = jsonArray.getJSONObject(i);
String tag_servicio = jsonObject.getString("contratista");
String servicio = jsonObject.getString("descipcion_del_problema");
String zona = jsonObject.getString("zona");
String money = jsonObject.getString("precio_min");
//Toast.makeText(Activity_Services_Worker.this, tag_servicio+servicio+zona+money, Toast.LENGTH_SHORT).show();
services.add(new Servicios_worker(tag_servicio, servicio, zona, money));
;; CHANGED
adapter.notifyDatasetChanged();
}
}catch (JSONException e){
e.printStackTrace();
}
}
}, new Response.ErrorListener(){
#Override
public void onErrorResponse (VolleyError error){
Log.e(TAG, "Registration Error: " + error.getMessage());
Toast.makeText(Activity_Services_Worker.this, error.getMessage(), Toast.LENGTH_LONG).show();
}
});
requestQueue.add(stringRequest);
