I'm new to android development. I'm trying to send some data to server using volley. But it is not sending parameters. Please help. The server is saying that the parameter is not set. I checked with the isset in php. When I tried sending data from a html form, it's working. But the volley is not sending the parameters.
public class MainActivity extends AppCompatActivity {
EditText uname;
EditText uotp;
RequestQueue myqueue;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
uname = (EditText) findViewById(R.id.uname);
uotp = (EditText) findViewById(R.id.uotp);
myqueue = Volley.newRequestQueue(this);
}
public void sendotp(View v)
{
String unameval = uname.getText().toString();
if(unameval.matches(""))
{
Toast.makeText(getApplicationContext(), "Enter Phone Number", Toast.LENGTH_SHORT).show();
}
else
{
HashMap<String, String> params = new HashMap<>();
params.put("phone", unameval);
String myUrl = "http://privateurlhere";
JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, myUrl, new JSONObject(params), new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
String dispname = response.getString("stat");
Toast.makeText(getApplicationContext(), dispname, Toast.LENGTH_SHORT).show();
}
catch(JSONException e)
{
Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_SHORT).show();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getApplicationContext(),"Resp err" + error.toString(), Toast.LENGTH_SHORT).show();
}
});
myqueue.add(request);
}
}

I'm trying to retrieve the JSON from an API but I'm not getting anything.
The JSON :
{"coord":{"lon":90.41,"lat":23.71},"weather":[{"id":721,"main":"Haze","description":"haze","icon":"50n"}],"base":"stations","main":{"temp":25,"feels_like":28.6,"temp_min":25,"temp_max":25,"pressure":1011,"humidity":83},"visibility":3500,"wind":{"speed":1.5,"deg":90},"clouds":{"all":75},"dt":1588093825,"sys":{"type":1,"id":9145,"country":"BD","sunrise":1588029983,"sunset":1588076702},"timezone":21600,"id":1185241,"name":"Dhaka","cod":200}
I did add INTERNET permission :
<uses-permission android:name="android.permission.INTERNET" />
My code :
private void httpGet() {
// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(this);
String url = "https://api.openweathermap.org/data/2.5/weather?q=" + CITY + "&units=metric&appid=" + API;
//https://api.openweathermap.org/data/2.5/weather?q=dhaka,bd&units=metric&appid=5694263c8d821570bfccff2a13246a73
Log.d("TEST", "Fonction lancee 1/2" + url);
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest
(Request.Method.GET, url, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d("TEST", "Fonction lancee 3/2" + response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("TEST", "Erreur");
}
});
queue.add(jsonObjectRequest);
}
I also tested with StringRequest with the same result, no response.

You can test the page of my JSON, the address is in comment in my code, (there is a comma in the city), it works.

I am a new developer in android.
I looked at the sources and made the parse from one link. But I have four links. How do I parse the four links?
Instead of having a String url, create an ArrayList of Strings that holds all your URLs.
In the method onClick() loop through the URLs.
Note that the ArrayList is filled in onCreate. I also added a try/catch clause in onClick, so if something goes wrong with one URL, the others will be parsed anyways.
Handling different URLs:
For parsing the Koinim ticker, you needed the key "sell", for Paribu you will need "last".
In the loop I am checking if the URL contains either Koinim or Paribu and adjust they key accordingly.
ArrayList<String> urls = new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn = (Button) findViewById(R.id.btn_get_information);
price = (TextView) findViewById(R.id.price);
urls.add("https://koinim.com/ticker/");
urls.add("url2");
urls.add("url3");
urls.add("url4");
btn.setOnClickListener(this);
}
#Override
public void onClick(View v) {
if (v.getId() == R.id.btn_get_information) {
for (String url : urls) {
try {
JsonObjectRequest request = null;
if(url.contains("koinim"))
{
request = getSellPrice("sell");
}
else if(url.contains("paribu"))
{
request = getSellPrice("last");
}
if(request != null)

MySingleton.getmInstance(getApplicationContext()).
addToRequestQue(jsonObjectRequest);

// something went wrong, handle exception here

try changing your Content-Type
application/json;charset=utf-8
to
application/json
I am fetching json data through Volley. The problem I am having
is that Volley's onResponse is never called, and hence the data are not parsed and displayed.
Sample JSON data
{
"title": "This is a sample text title title",
"cat": {
"origin" : "United states",
"target" : "Asia",
},
"content": "Lorem ipsum ipsum trxt hag jlak jshss jsyts pjqgq uuqtyq usiuqjo uwywh",

The things I know
In logcat, loadNews method is called.
I'm logging Volley, and from logcat volley is not complaining in anyway
I can't see "onResponse called NewsDetails" in logcat, meaning that for some reason not known to me, it's not called
So, my question is why is onResponse not called and how should I fix it?
You should use JsonObjectRequest instead of JsonArrayRequest because you are getting jsonobject in the response.
For getting more knowledge you may go through Volley tutorial
/* you are getting json in response but your response listener method is get Json Array replace your code with below code and also add an debug point in your error listener method */
private void loadNews() {
Log.d(TAG, "loadNews called");
mProgresscircle = new ProgressDialog(NewsDetails.this);
mProgresscircle.setCancelable(false);
mProgresscircle.setMessage(null);
mProgresscircle.show();
int news_id = getIntent().getIntExtra("NewsId", -1);
Toast.makeText(NewsDetails.this, "News id is" + news_id, Toast.LENGTH_SHORT).show();
final JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST,
DetailConfig.GET_DURL, requestParam,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d("Debug", response.toString());
//TODO parsing code
parseNews(response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d("", "Error: " + error.getMessage());
}
});
//Creating request queue
RequestQueue requestQueue = Volley.newRequestQueue(this);
//Adding request to queue
requestQueue.add(djsonArrayRequest);
}
// or replace this code into your into your loadNews method
final JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST,
DetailConfig.GET_DURL, requestParam,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d("Debug", response.toString());
//TODO parsing code
parseNews(response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d("", "Error: " + error.getMessage());
}
});
