to
String URL = "http://added-platters.000webhostapp.com/application/index.php";

Android Volley post request not working on click?

Im creating an application where i can make reports and,on button click nothing happens,even the response does not come,toast not showing up. This volley post i have used it before and it is correct,another thing i should write is that i have to send the token for authorization.
this is my code:
//this is button click
btnUpload.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
volley_send();
}
});
//-----------------------------------------------------
//this is volley post
private void volley_send(){
StringRequest stringRequest = new StringRequest(Request.Method.POST, "my_url",
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
// save_on_sharedPreference("email",email);
if(!response.isEmpty()){
try {
JSONObject jsonObject = new JSONObject(response);
error = jsonObject.getBoolean("error");
String message = jsonObject.getString("message");
if(!error){
//String token = jsonObject.getString("token");
//JSONObject data = jsonObject.getJSONObject("data");
Toast.makeText(getApplicationContext(),message,Toast.LENGTH_SHORT).show();
Intent intent = new Intent(getApplicationContext(), Raport_Cat_NoPhoto.class);
startActivity(intent);
}
else{
Toast.makeText(getApplicationContext(),message,Toast.LENGTH_SHORT).show();
}
// JSONArray feedArray = response.getJSONArray("data");
} catch (JSONException e) {
e.printStackTrace();
System.out.println("JSONException :"+e.toString() );
}
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
if (error instanceof TimeoutError || error instanceof NoConnectionError) {
Toast.makeText(getApplicationContext(),getString(R.string.err_connection),Toast.LENGTH_SHORT).show();
} else if (error instanceof AuthFailureError) {
//TODO

}
}
}){

return headers;
}

params.put("category","cat_ankese");
params.put("description",description.getText().toString());
params.put("city",Qyteti);
params.put("fshati",fshati.getText().toString());
params.put("address",address.getText().toString());

params.put("email",email.getText().toString());
params.put("info_latt",my_latitude);
params.put("info_long",my_longitude);
params.put("file[]",image123);
return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(getApplicationContext());
requestQueue.add(stringRequest);
}
I don't know what it is wrong...

Sems like the problem was with the Authorization header,for any reason it requires only one parameter. Thank you all for replies!

thanks in advance!

VollyJson library have a capability to differentiate different network errors while communicating with webservices.When something went wrong with JSONObjectRequest onErrorResponse will be called,there you can differentiate the error as follows.
public void onErrorResponse(VolleyError error) {
if (error instanceof TimeoutError || error instanceof NoConnectionError) {
//Write Your code here
} else if (error instanceof AuthFailureError) {
//TODO
} else if (error instanceof ServerError) {
//TODO
} else if (error instanceof NetworkError) {
//TODO
} else if (error instanceof ParseError) {
//TODO
}

Send post data to server using Volley android

I am trying to send some data to the server using the Volley library.
private void registerUser(final String email, final String username,
final String password) {
// Tag used to cancel the request
String tag_string_req = "req_register";
pDialog.setMessage("Registering ...");
StringRequest strReq = new StringRequest(Method.POST,
AppConfig.URL_REGISTER, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d(TAG, "Register Response: " + response.toString());
try {
JSONObject jObj = new JSONObject(response);
// String status = jObj.getString("status");
// User successfully stored in MySQL
// Now store the user in sqlite
String name = jObj.getString("username");
String email = jObj.getString("email");
String password = jObj.getString("password");
// String created_at = user
//.getString("created_at");
// Inserting row in users table
// db.addUser(name, email);
// Launch login activity
Intent intent = new Intent(
RegisterActivity.this,
LoginActivity.class);
startActivity(intent);
finish();
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e(TAG, "Registration Error: " + error.getMessage());
Toast.makeText(getApplicationContext(),
error.getMessage(), Toast.LENGTH_LONG).show();
}
}) {
#Override
protected Map<String, String> getParams() {
// Posting params to register url
Map<String, String> params = new HashMap<String, String>();
params.put("email", email);
params.put("username", username);
params.put("password", password);
return params;
}
Unfortunately no json is sent and I get nothing back. Here is a sample of my logcat output. After sending a request successfully to the server, I want to get response with success/fail.

Use Volley like this,... It is working for me.

First of all you are not sending json to your server. You are sending parametrized url with post method and getting json text as response.
I think the problem is the response from the server which is supposedly json. But from your log, this text "---- YOUR DATA ----" which you get from Log.d(TAG, "Register Response: " + response.toString()); is not at all json formatted . So you need to modify your server to respond in correct json format.

This is the solution. I had to use the JsonObjectRequest class and not the StringRequest on. What JsonRequest does is that it converts your HashMap key-value pairs into a JSON Format.
private void registerUser(String email_address,String username, String
password) {
String tag_json_obj = "json_obj_req";
final ProgressDialog pDialog = new ProgressDialog(this);
pDialog.setMessage("posting...");
pDialog.show();
final String mVendorId =
DeviceDetails.getInstance(mContext).getVendor_id();
String mUserId = UserModel.getInstance(mContext).getUser_id();
String location = getResources().getConfiguration().locale.getCountry();
final HashMap<String, String> postParams = new HashMap<String, String>
();
postParams.put("username", username);
postParams.put("email", email_address);
postParams.put("password", password);
postParams.put("location", location);
Response.Listener<JSONObject> listener;
Response.ErrorListener errorListener;
final JSONObject jsonObject = new JSONObject(postParams);
JsonObjectRequest jsonObjReq = new
JsonObjectRequest(AppConfig.URL_REGISTER, jsonObject,
new com.android.volley.Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
//Log.d("TAG", response.toString());
try {
Toast.makeText(getApplicationContext(),
response.getString("message"), Toast.LENGTH_LONG).show();
// Toast.makeText(getApplicationContext(), "Thank
you for your post", Toast.LENGTH_LONG).show();
if (response.getString("status").equals("success")){
session.setLogin(true);
pDialog.dismiss();
Intent i = new
Intent(RegisterActivity.this,Welcome.class);
startActivity(i);
finish();
}
} catch (JSONException e) {
Log.e("TAG", e.toString());

pDialog.dismiss();
