I have two nested VOLLEY GET request. The first API request gives me id field which I am using to called another Web Service. The problem is the way I am getting the sequence of id from first request its not calling the same sequence for second request which uses id field return by first request.
This is my nested VOLLEY GET request.
private void getData() {
final JsonArrayRequest request = new JsonArrayRequest(Request.Method.GET, ApiUrls.RESERVATION, null, new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
for (int i = 0; i < response.length(); i++) {
try {
JSONObject object = response.getJSONObject(i);
final Entry entry = newEntry();
String Id = object.getString("id");
entry.setId(Id);
ID_url = ApiUrls.DETAILS + Id + "/";
JsonObjectRequest foodieInfo = new JsonObjectRequest(Request.Method.GET, ID_url, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
String firstName = response.getString("firstname");
entry.setName(firstName);
adapter.notifyDataSetChanged();
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = new HashMap<>();
String auth = "JWT " + myToken;
headers.put("Authorization", auth);
headers.put("Content-Type", "application/json");
return headers;
}
};
AppController.getInstance().addToRequestQueue(foodieInfo);
current.add(entry);
adapter = new ReservationAdapter(current, getActivity().getApplicationContext());
recyclerView.setAdapter(adapter);
adapter.notifyDataSetChanged();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = new HashMap<>();
String auth = "JWT " + myToken;
headers.put("Authorization", auth);
headers.put("Content-Type", "application/json");
return headers;
}
#Override
protected Response<JSONArray> parseNetworkResponse(NetworkResponse response) {
int status=response.statusCode;
if(status==200){
}
return super.parseNetworkResponse(response);
}
};
AppController.getInstance().addToRequestQueue(request);
}
The id which I get in first request same it should be only used in the Nested JSON GET request. But it take different id returned by first request and called the another request from using that sequence. How to resolve this ?

I am looking to do as per the image says:
Following is the code I am trying to implement from that image:
RequestQueue queue = Volley.newRequestQueue(this);
String url ="https://api.kairos.com/enroll";
StringRequest stringRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
// Display the first 500 characters of the response string.
Log.i("Response is: " , response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// mTextView.setText("That didn't work!");
}
})
{
#Override
protected Map<String, String> getParams()
{
Map<String, String> params = new HashMap<String, String>();
params.put("app_id", "4985f625");
params.put("app_key", "aa9e5d2ec3b00306b2d9588c3a25d68e");
return params;
}
};
// Add the request to the RequestQueue.
queue.add(stringRequest);
Now I do not get how to add that JSONObject part into my POST Request, and also how to add the Content-Type Header.
I found a similar question here. See the code below. You have to override the getBodyContentType method.
public String getBodyContentType()
{
return "application/json";
}
for content type header you can do the following
StringRequest request = new StringRequest(Request.Method.PUT,
url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
listener.onResponse(response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(#NonNull VolleyError error) {
if (error.networkResponse != null) {
errorListener.onErrorResponse(error.networkResponse.statusCode, null);
} else {
Log.e(TAG, "An error occurred while trying to verify sms: ", error);
errorListener.onErrorResponse(500, null);
}
}
}) {
#NonNull
#Override
protected Map<String, String> getParams() {
return data;
}
#NonNull
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = new HashMap<>();
headers.put("Content-Type",
"application/x-www-form-urlencoded");
return headers;
}
};
And for send Json object I suggest create Json object like this
JSONObject jsonObject = new JSONObject();
try {
jsonObject.put("11", 3);
jsonObject.put("12", 4);
jsonObject.put("13", 5);
} catch (JSONException e) {
e.printStackTrace();
}
Then you can pass this object as string by jsonObject.toString() and pass it in parameters like pass any string like the following
#NonNull
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("json", jsonObject.toString();
return params;
}
I'm trying to get access tokens from the server using a volley String request. I have tried making a JsonObjectRequest also. Both are below.
public void getAuthenticationTokens(Object param1, final CustomListener<String> listener)
{
//String url = prefixURL + "this/request/suffix";
String url = "https://lw.xxx.co.uk/connect/token";
StringRequest request = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>()
{
#Override
public void onResponse(String response) {
// response
Log.e("Response", response);
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error) {
// error
Log.e("Error.Response", error.networkResponse.toString());
}
}
) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String,String> params = new HashMap<>();
params.put("Content-Type","application/x-www-form-urlencoded");
//..add other headers
return params;
}
#Override
protected Map<String, String> getParams()
{
Map<String, String> params = new HashMap<String, String> ();
params.put("scope", "openid email phone profile offline_access roles");
params.put("resource", "window.location.origin");
params.put("grant_type", "password");
params.put("username", "support#xxx.com");
params.put("password", "tempPxxx");
return params;
}
};
requestQueue.add(request);
.
public void getAuthenticationTokens(Object param1, final CustomListener<String> listener)
{
//String url = prefixURL + "this/request/suffix";
String url = "https://lw.xxx.co.uk/connect/token";
Map<String, Object> jsonParams = new HashMap<>();
jsonParams.put("scope", "openid email phone profile offline_access roles");
jsonParams.put("resource", "window.location.origin");
jsonParams.put("grant_type", "password");
jsonParams.put("username", "support#xxx.com");
jsonParams.put("password", "tempPxxx");
JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, url, new JSONObject(jsonParams),
new Response.Listener<JSONObject>()
{
#Override
public void onResponse(JSONObject response)
{
Log.d(TAG + ": ", "somePostRequest Response : " + response.toString());
if(null != response.toString())
listener.getResult(response);
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error)
{
if (null != error.networkResponse)
{
Log.e(TAG + ": ", "Error Response code: " + error.networkResponse.statusCode);
listener.getResult(null);
}
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
// Map<String,String> params = super.getHeaders();
// if(params==null)params = new HashMap<>();
Map<String,String> params = new HashMap<>();
params.put("Content-Type","application/x-www-form-urlencoded");
//..add other headers
return params;
}
};
requestQueue.add(request);
.
I get the following response from the server:
E/Volley: [31388] BasicNetwork.performRequest: Unexpected response code 400 for https://lw.xxx.co.uk/connect/token
.
My colleague who has written the server-side code has asked how to convert the following Angular code (his code that works with the API), to Android.
Can anyone help with this?
getLoginEndpoint(userName: string, password: string): Observable<Response> {
let header = new Headers();
header.append("Content-Type", "application/x-www-form-urlencoded");
let searchParams = new URLSearchParams();
searchParams.append('username', userName);
searchParams.append('password', password);
searchParams.append('grant_type', 'password');
searchParams.append('scope', 'openid email phone profile offline_access roles');
searchParams.append('resource', window.location.origin);
let requestBody = searchParams.toString();
return this.http.post(this.loginUrl, requestBody, { headers: header });
}
The problem was a couple of things.
I replaced "params.put("resource", "window.location.origin"); " with "params.put("resource", "https://lw.xxx.co.uk");"
Also, I found out that Volley ignore the getHeaders override, so I commented that method out and used the following to set the headers.
#Override
public String getBodyContentType() {
return "application/x-www-form-urlencoded";
}
public void getAuthenticationTokens(Object param1, final String userName, final String password, final CustomListener<JSONObject> listener)
{
String url = "https://lw.xxx.co.uk/connect/token";
StringRequest request = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>()
{
#Override
public void onResponse(String response) {
// response
Log.e("Response", response);
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error) {
// error
Log.e("Error.Response", error.networkResponse.toString());
}
}
) {
/* #Override

return params;
}

return super.parseNetworkError(response);

I am using Sinch to create an app in android and some of the functionalities that I need can only be implemented by calling their REST API. I want to mute a particular user, for that I have written the code like this
String userName = call.getCallId();
final String muteURL = URL+CallingUsersName+"/"+userName;
final String muteParticipant = "{ \"command\" : \"mute\" }";
JSONObject muteJSON;
try{
muteJSON = new JSONObject(muteParticipant);
Toast.makeText(getActivity(),muteJSON.toString(),Toast.LENGTH_SHORT).show();
}catch (JSONException e ) {
muteJSON = null;
Toast.makeText(getActivity(), e.toString(), Toast.LENGTH_SHORT).show();
}
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.PATCH, muteURL, muteJSON, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
mConferenceParticipants.setText(response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
mConferenceParticipants.setText(error.toString());
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> params = new HashMap<String, String>();
String creds = String.format("%s:%s",AppKey,AppSecretKey);
String auth = "Basic " + Base64.encodeToString(creds.getBytes(), Base64.NO_WRAP);
params.put("Authorization", auth);
params.put("Content-Type", "application/json");
// params.put("X-HTTP-Method-Override", "PATCH");
return params;
// return super.getHeaders();
}
};
// jsonObjectRequest.setRetryPolicy(new DefaultRetryPolicy(8000,DefaultRetryPolicy.DEFAULT_MAX_RETRIES,DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
rq.add(jsonObjectRequest);
When I call this request the meeting is actually going on but I am getting this error
BasicNetwork.performRequest: Unexpected response code 400 for https://callingapi.sinch.com/v1/conferences/id/Meeting/a291ba94-e430-454f-80a9-73013cd43451
I believe that 400 means Conference not found but the conference is established and in the same activity I am also calling the REST API that will tell me the no. of participants in the meeting and that is working correctly.
Any idea what is wrong in this?
I tried to solve this problem for a long time and finally got it working. Here is the code:
public void MuteTheParticipants(){
String userName = call.getCallId();
final String muteURL = URL+CallingUsersName+"/"+userName;
StringRequest sr = new StringRequest(Request.Method.PATCH, muteURL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
if(flag)
muteButton.setBackgroundResource(R.drawable.microphone);
else
muteButton.setBackgroundResource(R.drawable.microphone_off
);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getActivity(),error.toString(),Toast.LENGTH_SHORT).show();
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> params = new HashMap<String, String>();
String creds = String.format("%s:%s",AppKey,AppSecretKey);
String auth = "Basic " + Base64.encodeToString(creds.getBytes(), Base64.NO_WRAP);
params.put("Authorization", auth);
return params;
// return super.getHeaders();
}
#Override
protected Map<String, String> getParams() throws AuthFailureError {
HashMap<String, String> params = new HashMap<String, String>();
if(!flag) {
params.put("command", "mute");
flag = true;
}else {
params.put("command", "unmute");
flag = false;
}
return params;
}
};
sr.setRetryPolicy(new DefaultRetryPolicy(8000,DefaultRetryPolicy.DEFAULT_MAX_RETRIES,DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
rq.add(sr);
}
your variable says username, it should be callid you mute not username
From two days i am trying to solve this issue but still i have no any result,why each and every time volley returning me 403 error. where i m wrong? i am using postman to check same webservice, it returns success result. But same thing when i am using in Android via volley or httpurlconnection getting 403 error.kindly help me to find my error.
This is my code which i have tried:
StringRequest jsonObjectRequest = new StringRequest(Request.Method.POST, Constant.posturl, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
String result=response;
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
NetworkResponse response = error.networkResponse;
int status = response.statusCode;
}
}) {
#Override
public Map<String, String> getHeaders() {
try {
headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json");
String credentials = Constant.USERNAME + ":" + Constant.PASSWORD;
String auth = "Basic " + Base64.encodeToString(credentials.getBytes(), Base64.DEFAULT);
headers.put("Authorization", auth);
return headers;
} catch (Exception e) {
e.printStackTrace();
return headers;
}
}
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("title", heading_edit_text.getText().toString());
params.put("content", body_edit_text.getText().toString());
params.put("Slug", heading_edit_text.getText().toString());
params.put("date", currentDate);
return params;
}
};
jsonObjectRequest.setRetryPolicy(new DefaultRetryPolicy(50000, 3, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
requestQueue.add(jsonObjectRequest);
Volley does provide a proper request for this which is called JsonObjectRequest.
String webAddress = "url here";
RequestQueue queue = Volley.newRequestQueue(this); // singletone here
JSONObject object = new JSONObject();
try {
object.put("title", heading_edit_text.getText().toString());
object.put("content", body_edit_text.getText().toString());
object.put("Slug", heading_edit_text.getText().toString());
object.put("date", currentDate);
} catch (JSONException e) {
}
JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, webAddress,object, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject object) {
Log.d("RESPONSE", object.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError volleyError) {
Log.d("RESPONSE", "That didn't work!");
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> header = new HashMap<>();
// content type is not needed here
header.put("Authorization", "value here");
return header;
}
};
queue.add(request);
Change the "Content-Type" of your headers to "application/form-data"
ie,
headers.put("Content-Type", "application/form-data");
I was also face this issue in news api. But when I use Retrfit its work like a charm.
I need to call an api that expects a string array as a POST parameter. So for an example of an API definition:
POST api/names
POST parameter expected is an array of names and some other attributes like below:
{ names: [ "John", "Bill" ], department: "Engineering" }
I am currently using a custom Volley framework as described in the Android documentation but it seems like the parameters from Volley can only be passed as a Map of (String, String as key and value). I already have the array from my Android app, ready to be passed as a post parameter but this Volley expects a String.
I tried to convert my array using Arrays.toString(myStringArray) and passed it like below but it does not work.
String[] namesArray = new String[1];
namesArray[0] = "Bill";
Map<String, String> mapParams = new HashMap<String, String>();
mapParams.put("department", "Computer Science");
mapParams.put("names", Arrays.toString(namesArray));
// Then call the Volley here passing the mapParams.
How can I call the api that expects a String of array when I can only use a String from Volley?
I will give you full code to post JsonObject on volley, through POST method.
JSONObject js = new JSONObject();
try {
js.put("genderType", "MALE");
}
} catch (JSONException e) {
e.printStackTrace();
}
String url = "LINK TO POST/";
// Make request for JSONObject
JsonObjectRequest jsonObjReq = new JsonObjectRequest(
Request.Method.POST, url, js,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.e(TAG, "Response_Code from Volley" + "\n" + response.toString() + " i am king");
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.e(TAG, "Error: " + error.getMessage());
NetworkResponse response = error.networkResponse;
if (error instanceof ServerError && response != null) {
try {
String res = new String(response.data,
HttpHeaderParser.parseCharset(response.headers, "utf-8"));
// Now you can use any deserializer to make sense of data
Log.e(TAG, "onErrorResponse: of uploadUser" + res);
// JSONObject obj = new JSONObject(res);
} catch (UnsupportedEncodingException e1) {
// Couldn't properly decode data to string
e1.printStackTrace();
}
}
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json");
return headers;
}
};
Log.e(TAG, "uploadUser: near volley new request ");
// Adding request to request queue
Volley.newRequestQueue(this).add(jsonObjReq);
}
Put anything you need in the js object with key and its values
Use JsonObjectRequest and simply pass a JSONObject. There's a full example here
public void makePostRequest(final Map<String,String> myMap,String MEDIA_URL,final VolleyResponse callback)
{
VolleySingleton VS;
Log.e("URL",MEDIA_URL);
VS=VS.getInstance();
RequestQueue rq=VS.getRequestQueue();
StringRequest stringRequest = new StringRequest(Request.Method.POST,MEDIA_URL,
new Response.Listener<String>() {
#Override
public void onResponse(String s) {
callback.onSuccess(s);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError volleyError) {
callback.onError();
}
}){
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String,String> params = new Hashtable<String, String>();
Iterator<Map.Entry<String, String>> iterator = myMap.entrySet().iterator();
while(iterator.hasNext()) {
Map.Entry<String,String> pairs = (Map.Entry<String,String>)iterator.next();
String value = pairs.getValue();
String key = pairs.getKey();
params.put(key,value);
Log.e("Key","Value"+value);
}
return params;
}
};
//Creating a Request Queue
// RequestQueue requestQueue = Volley.newRequestQueue(this);
DefaultRetryPolicy retryPolicy = new DefaultRetryPolicy(0, -1, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
stringRequest.setRetryPolicy(retryPolicy);
//Adding request to the queue
rq.add(stringRequest);
}
Where the VolleyResponse is a simple custom interface like this
public interface VolleyResponse {
void onSuccess(String resp);
void onError();
}
