I am developing an android app in which I have created a custom API for database. I am using volley for HTTP request. I am getting "com.android.volley.AuthFailureError" error on my onErrorResponse. I have checked the JSONObject in the debugger and it's valid.Moreover, I am using "application/json" in the header.
I am unable to find a way to fix this error. Here is the JsonRequest.
Here I am trying to use JSONRequest:
public void jsonPOST(String jsonInput) {
RequestQueue queue = Volley.newRequestQueue(getActivity().getApplicationContext());
String URL = "http://Servername:8080/users";
try{
JsonObjectRequest req = new JsonObjectRequest(URL, new JSONObject(jsonInput),
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
VolleyLog.v("Response:%n %s", response.toString(4));
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.e("Error: ", error.getMessage());
}
});
queue.add(req);
}
catch (JSONException error){
String output = error.toString();
}
}
I have checked the JSONObject in the debugger and it's valid. I am also checked the network firewall but it also seems fine

I'm trying to send a simply JSON request using Volley JsonObjectRequest.
After getting the JSON response, I would like to update a value called valoreConvertito, but the JSON response is null and consequently valoreConvertito remains zero.
private void convertiREST(final Double valoreDaConvertire, String valuta){
final TextView textView = (TextView) findViewById(R.id.text);
RequestQueue queue = Volley.newRequestQueue(this);
String url =COMPLETEURL;
valoreConvertito = 0.0;
JsonObjectRequest objectRequest = new JsonObjectRequest(
Request.Method.GET,
url,
null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
Log.e("Rest response ", response.toString());
valoreConvertito = response.getJSONObject("quotes").getDouble("valuta");
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("Rest response", error.toString());
}
});
queue.add(objectRequest);
}
I've even followed the suggestions in another post (Volley JsonObjectRequest response) but I still got JSON response null.
Using the debugger it seems that the program doesn't enter neither in onResponse nor in ErrorListener.
After adding the row queue.add(objectRequest); I notice in Logcat the HTTP traffic not permitted error and I've solved my issue following Android 8: Cleartext HTTP traffic not permitted post.
I have build a laravel Rest API with a Jason Web Token. Now I want to make a App which sends data to the Webservice. Here I try to authentificate myself (with name email and password) at first but I do not get the token as a answer. I also do not get a error, nothing happens.
private void sendAndRequestResponse() {
try {
JSONObject jsonBody = new JSONObject();
jsonBody.put("name", "ida");
jsonBody.put("email", "ida#gmail.com");
jsonBody.put("password", "secret");
final String mRequestBody = jsonBody.toString();
//RequestQueue initialized
mRequestQueue = Volley.newRequestQueue(this);
mJsonRequest = new JsonObjectRequest(
Request.Method.POST, url, jsonBody,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
answer.setText(response.toString());
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
}
});
mRequestQueue.add(mJsonRequest);
} catch (JSONException e) {
e.printStackTrace();
}
}
you need to start request queue in order to make the request call.
after
mRequestQueue.add(mJsonRequest);
add following
mRequestQueue.start();
I have a webservice which returns json files. If I call this url (http://192.168.178.67:8080/simplestock/webapi/swipeService/swipes/Aktien) on my smartphone browser, I will get a json array back.
Now I've tried to get this json in my android project with this code:
JsonArrayRequest jsonObjectRequest = new JsonArrayRequest
(Request.Method.GET, url, null, new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Log.d("Success", "onResponse is Called");
try {
Log.d("Get Object: ", response.getJSONArray(1).toString());
} catch (JSONException e) {
e.printStackTrace();
Log.d("Failure", "JSON Error");
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("JSON", "Error");
}
});
The problem is that the respond isn't called and I don't get any error message. I've added the internet permission in the manifest. I test on my smartphone, which is in the same network than the localhost. Anybody got an idea?
In what ever method you are calling your code you need to add the request to the queue: jsonObjectRequest.add(jsonArrayRequest);
Like this:
JsonArrayRequest jsonObjectRequest = new JsonArrayRequest
(Request.Method.GET, url, null, new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Log.d("Success", "onResponse is Called");
try {
Log.d("Get Object: ", response.getJSONArray(1).toString());
} catch (JSONException e) {
e.printStackTrace();
Log.d("Failure", "JSON Error");
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("JSON", "Error");
}
});
jsonObjectRequest.add(jsonArrayRequest);
I am familiar with Volley and creating a Singleton class, and adding requests to the queue. However, I wish to increase the modularity of volley and simply call all requests through method call to another class instead. I have setup the present action as basis for the common GET request:
public Object getRequest(String params) {
final JSONObject getRequestReturn = new JSONObject();
JsonObjectRequest getRequest = new JsonObjectRequest(Request.Method.GET,
VolleySingleton.prefixURL, ((String) null),
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
// Parse the JSON:
try {
getRequestReturn = response;
Log.v("GET Request value", response.toString());
} catch (JSONException e) {
e.printStackTrace();
} catch (NullPointerException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("GET Request Error", error.toString());
}
});
mRequestQueue.add(getRequest);
return getRequestReturn;
}
However, I have a the perplexing catch 22 error on the assignment of response at:
getRequestReturn = response;
The error notes that getRequestReturn must be declared final to allow for use within the inner class, but upon assigning final, another error appears noting that you cannot assign a value to a final variable.
How can this method be handled?
Declare JSONObject as global and initialize in same place like this.
JSONObject getRequestReturn ;
getRequestReturn = new JSONObject();
public Object getRequest(String params) {
JsonObjectRequest getRequest = new JsonObjectRequest(Request.Method.GET,
VolleySingleton.prefixURL, ((String) null),
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
// Parse the JSON:
try {
Log.v("GET Request value", response.toString());
} catch (JSONException e) {
e.printStackTrace();
} catch (NullPointerException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("GET Request Error", error.toString());
}
});
mRequestQueue.add(getRequest);
return new JSONObject();
}
U can't get response when u return!Volley request is async!
I use EventBus and I do it like this ：
When I need to get data from web , i add a request like this.
Then when i get response from web ,I use EventBus to post a event.
I get the event and update my page.
Or U can try the RxAndroid.
Maybe this is a silly question but I've been stucked on this for a while. I'm implementing some methods for a restApi. I'm using retrofit and I'm trying to update a client information. To do an update I'm using PUT method but I don't know why I'm always getting a 301 CODE and I can't update the information. Here is my code, thank you for everything.
public interface ClientInterface {
#GET("/clients/{clientParam}")
public Client fetchClient(#Path("clientParam") String client);
#GET("/clients/")
public void fetchAllClients(Callback<List<Client>> callback);
#POST("/clients/")
public void newClient(#Body Client client, Callback<Client> callback);
#PUT("/clients/{clientParam}/")
public void updateClient(#Path("clientParam") String cod, #Body Client client,Callback<Client> callback);
}
After that I use the update method in the following way
RestAdapter restAdapter = new RestAdapter.Builder().setEndpoint(Utils.getURLPreferences(DatosClienteActivity.this)).build();
ClientInterface clientRestInter = restAdapter.create(ClientInterface.class);
Client clientsUpdate = new Client();
//Fetch data into clientsUpdate object
clientRestInter.updateClient(codClient, clientsUpdate, new Callback<Client>() {
#Override
public void success(Client client, retrofit.client.Response response) {
}
#Override
public void failure(RetrofitError error) {
error.printStackTrace();
}
});
EDIT:
If I use volley against the same URL it's working perfectly...
RequestQueue queue = Volley.newRequestQueue(this);
final JSONObject jsonObject = new JSONObject();
try {
//Construct jsonObject
} catch (JSONException e) {
e.printStackTrace();
}
JsonObjectRequest req = new JsonObjectRequest(Request.Method.PUT, URL, jsonObject,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
VolleyLog.v("Response:%n %s", response.toString(4));
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.e("Error: ", error.getMessage());
error.printStackTrace();
}
});
queue.add(req);
Finally I solved it.
The problem was that we had two different Client objects and the one that you fetch is the one that you must change and use it to upload with PUT.
I hope that this help somebody.
