Request Https url using Volley

Request Https url using Volley - android

I want to request a webservice with https url, but a Volley Error Occurs (NoConnectionError).
I think the problem is that https url, but I don't found any solution on internet.
Anybody can helps me?
The error is: "com.android.volley.NoConnectionError: java.io.IOException: No authentication challenges found"
Code:
RequestQueue queue = VolleySingleton.getInstance(this).getRequestQueue();
String url = "https://www.websiteco.com/rest/index.php/login/user/email/ana#gmail.com/password/123456";
JsonObjectRequest json = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
String s = response.toString();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
String errorStr = "";
if (error instanceof TimeoutError || error instanceof NoConnectionError) {
errorStr = "TimeoutError or NoConnectionError";
} else if (error instanceof AuthFailureError) {
errorStr = "AuthFailureError";
} else if (error instanceof ServerError) {
errorStr = "ServerError";
} else if (error instanceof NetworkError) {
errorStr = "NetworkError";
} else if (error instanceof ParseError) {
errorStr = "ParseError";
}
Toast.makeText(getApplicationContext(),errorStr,Toast.LENGTH_LONG).show();
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> parms = new HashMap<>();
parms.put("Key-Api", "*******");
return parms;
}
#Override
protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {
try {
String jsonString = new String(response.data,
HttpHeaderParser.parseCharset(response.headers));
return Response.success(new JSONObject(jsonString),
HttpHeaderParser.parseCacheHeaders(response));
} catch (UnsupportedEncodingException e) {
return Response.error(new ParseError(e));
} catch (JSONException je) {
return Response.error(new ParseError(je));
}
}
};
queue.add(json);

google/volley App crashing when URL do not exist

So I've implemented google/volley in my apps. When i code the apps i accidentally mistyped the url address and the app just crash suddenly. So how can i avoid this kind of problem. Below are the code i've used.
String url_login = "http://10.0.2.2/test_sstem/public/login";
//Send Post data and retrieve server respond
StringRequest stringRequest = new StringRequest(Request.Method.POST, url_login,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Toast.makeText(LoginActivity.this,"On Response "+response,Toast.LENGTH_LONG).show();
ValidateLogin(response);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
NetworkResponse networkResponse = error.networkResponse;
if (networkResponse != null && networkResponse.data != null) {
String jsonError = new String(networkResponse.data);
String message_response=null;
try {
JSONObject object = new JSONObject(jsonError);
message_response= object.getString("error");
} catch (JSONException e) {
e.printStackTrace();
}
Toast.makeText(LoginActivity.this, "On Error " + message_response.toString(), Toast.LENGTH_LONG).show();
showProgress(false);
}
}
})
I know that it can be fixed by correcting the URL, but what if the URL are not alive and working how do we work around this problem.

I have used bellow method for volley which is work for me.. i have used wrong address but my app does not stop. Use bellow full method..
private void doLoginAction() {
pDialog.show();
String url_login = "http://10.0.2.2/test_sstem/public/login";
StringRequest stringRequest = new StringRequest(Request.Method.POST, url_login,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
//pDialog.dismiss();
try {
JSONObject jsonObject = new JSONObject(response);
JSONArray loginNodes = jsonObject.getJSONArray("ParentNode");
for (int i = 0; i < loginNodes.length(); i++) {
JSONObject jo = loginNodes.getJSONObject(i);
String key1 = jo.getString("key1");
String key2 = jo.getString("key2");
}
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
pDialog.dismiss();
try {
if (error instanceof TimeoutError ) {
//Time out error
}else if(error instanceof NoConnectionError){
//net work error
} else if (error instanceof AuthFailureError) {
//error
} else if (error instanceof ServerError) {
//Erroor
} else if (error instanceof NetworkError) {
//Error
} else if (error instanceof ParseError) {
//Error
}else{
//Error
}
//End
} catch (Exception e) {
}
}
}) {
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<>();
params.put("uname", "era#gmail.com");
params.put("pass", "123456");
return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest);
}

There can be number of reasons why your app crashes with incorrect url, one could be that the host is un resolvable, you can check the validity of a Url by using the following code:
URLUtil.isValidUrl(url)

JSONObject not response

How do I check if this text appears or not
{"cod":"404","message":"city not found"}

}
}
else
{
Toast.makeText(MainActivity.this, "no Internet", Toast.LENGTH_SHORT).show();
}
}
I am trying to solve the problem 4 hours ago but no use
I think the problem here
String x = response.getString("message");
I need help please

You are getting json text in the response body, but the server is responding with 404 code which is an error, therefore the logic needs to be inside the overridden method:
#Override
public void onErrorResponse(VolleyError error) {
String body;
String statusCode = String.valueOf(error.networkResponse.statusCode);
if(statusCode == "400") {
// do your thing
}
// do something else
}

Json Might be look like
{"loginNodes":[{"message":"Welcome To Alamofire","name":Enamul Haque,"errorCode":"0","photo":null}]}
Your code should be ..
StringRequest stringRequest = new StringRequest(Request.Method.POST, "http://api.openweathermap.org/data/2.5/weather",
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
//pDialog.dismiss();
try {
JSONObject jsonObject = new JSONObject(response);
JSONArray loginNodes = jsonObject.getJSONArray("loginNodes");
pDialog.dismiss();
for (int i = 0; i < loginNodes.length(); i++) {
JSONObject jo = loginNodes.getJSONObject(i);
String message= jo.getString("message");
}
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
pDialog.dismiss();
try {
} catch (Exception e) {
}
}
}) {
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<>();
params.put("q", "fddfgdfgdfgdfg");
params.put("units", "metric");
params.put("appid", "efb8013262db1b77b0431909b8b173e1");
return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest);
Check response from GET OR Post.You can debug the error onErrorResponse
try {
if (error instanceof TimeoutError ) {
}else if(error instanceof NoConnectionError){
} else if (error instanceof AuthFailureError) {
} else if (error instanceof ServerError) {
//TODO
} else if (error instanceof NetworkError) {
//TODO
} else if (error instanceof ParseError) {
//TODO
}
} catch (Exception e) {
}

How to get JSON error response in Volley onErrorResponse

I have an API call with below details
URL: http://pankajservers.in/api/v1/AuthenticateUser with Input params
below
EmailAddress and Password
if I type wrong credentials, I get below JSON response with Status Code : 403
{"Status":false,"Message":"Invalid Credentials. 5 attempts left.","Data":null}
Below is the Error Response Code.
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error)
{
if (null != error.networkResponse)
{
Log.d(TAG + ": ", "Error Response code: " + error.networkResponse.statusCode);
}
}
});
Is there any way to get JSON response in this code block?
I tried this post: Volley handle onErrorResponse
But it seems it never execute parseNetworkError

To print the Error on that block you just need to obtain the Response bytes:
NetworkResponse networkResponse = error.networkResponse;
if (networkResponse != null && networkResponse.data != null) {
String jsonError = new String(networkResponse.data);
// Print Error!
}

You can create custom request like this:
public class BaseRequest extends Request {
private static final String TAG = BaseRequest.class.getSimpleName();
private final Gson gson = new Gson();
private final Response.Listener listener;
public BaseRequest(String url, Response.Listener responseListener, Response.ErrorListener listener) {
super(Request.Method.GET, url, listener);
Log.e(TAG, "Requesting url : " + url);
this.listener = responseListener;
}
public BaseRequest(int method, String url, Response.Listener responseListener, Response.ErrorListener listener) {
super(method, url, listener);
Log.e(TAG, "Requesting url : " + url);
this.listener = responseListener;
}
#Override
public Response parseNetworkResponse(NetworkResponse response) {
try {
String json = null;
json = new String(
response.data,
HttpHeaderParser.parseCharset(response.headers));
JSONObject result = new JSONObject(json);
if (!result.getBoolean("Status"))
return Response.success(
result.get("Data"),
HttpHeaderParser.parseCacheHeaders(response));
else
return Response.error(new VolleyError(result.getString("Message")));
} catch (UnsupportedEncodingException e) {
return Response.error(new ParseError(e));
} catch (JsonSyntaxException e) {
return Response.error(new ParseError(e));
} catch (JSONException e) {
return Response.error(new ParseError(e));
}
}
#Override
protected VolleyError parseNetworkError(VolleyError volleyError) {
return volleyError;
}
#Override
protected void deliverResponse(Object response) {
listener.onResponse(response);
}
}
and make request:
BaseRequest baseRequest = new BaseRequest(Request.Method.POST, url, new Response.Listener() {
#Override
public void onResponse(Object response) {
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e(TAG, "Error : " + error.getMessage());
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
//Your parameters
return params;
}
};
queue.add(baseRequest);

You can cast an error response to a Json Object
JSONObject jsonObject = new JSONObject();
JsonObjectRequest JO = new JsonObjectRequest(Request.Method.POST,"URL String Here",jsonObject, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
//Your Logic
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
try {
JSONObject JO = new JSONObject(error.toString());
}catch (JSONException e){
e.printStackTrace();
}
}
});

Connection Timeout Android

i have an android app in which i hit a web service and gets the result.
Now i want is if result is getting to long to be fetched or in between request internet connection is gone then i show a message or a dialog to the user that Your connection timed out
I've tried this code but this is not working
Any help would be appreciated
blic void getVolleyTask(Context context,
final IVolleyReponse responseContext, String URL) {
RequestQueue request = Volley.newRequestQueue(context);
StringRequest strReq = new StringRequest(Request.Method.GET, URL,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
if (response != null) {
JSONArray _array = new JSONArray(response);
responseContext.ResponseOk(_array);
} else {
responseContext.ResponseOk(null);
}
} catch (Exception e) {
e.printStackTrace();
responseContext.ResponseOk(null);
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
responseContext.ErrorBlock();
}
});
strReq.setRetryPolicy(new DefaultRetryPolicy(socketTimeout, maxTries,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
request.add(strReq);
}
public void getVolleyPostTask(Context context,
final IVolleyJSONReponse jsonResponseContext, String URL,
JSONObject obj) {
RequestQueue request = Volley.newRequestQueue(context);
JsonObjectRequest myRequest = new JsonObjectRequest(
Request.Method.POST, URL, obj,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
jsonResponseContext.ResponseOk(response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
jsonResponseContext.ErrorBlock();
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");
return headers;
}
};
myRequest.setRetryPolicy(new DefaultRetryPolicy(socketTimeout,
maxTries, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
request.add(myRequest);
}
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
}
