I'm trying to set up volley to pull down this JSONObject from iTunes
String url = "https://itunes.apple.com/search?term=michael+jackson";
The whole point is to parse the object to get the album art url for a particular song
So I set this code up to get the JsonObject, and I'm getting a couple of errors
Cannot resolve symbol ErrorListener
Cannot resolve symbol Listener
Here is the code with annotated errors
JsonObjectRequest jsonRequest = new JsonObjectRequest
(Request.Method.GET, url, null, new Downloader.Response.Listener // Cannot resolve symbol Listener
<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
// the response is already constructed as a JSONObject!
try {
response = response.getJSONObject("args");
String site = response.getString("site"),
network = response.getString("network");
System.out.println("Site: "+site+"\nNetwork: "+network);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Downloader.Response.ErrorListener // Cannot resolve symbol ErrorListener
() {
#Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
}
});
Volley.newRequestQueue(this).add(jsonRequest);
Try Response.ErrorListener
http://afzaln.com/volley/com/android/volley/Response.ErrorListener.html
There is no Downloader.ResposneListener
Change TO
StringRequest stringRequest = new StringRequest(DownloadManager.Request.Method.GET, url,
to
StringRequest stringRequest = new StringRequest(com.android.volley.Request.Method.GET, url,
Your code will be
JsonObjectRequest jsonRequest = new JsonObjectRequest
(Request.Method.GET, url, null, new com.android.volley.Response.Listener // CHANGES HERE
<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
// the response is already constructed as a JSONObject!
try {
response = response.getJSONObject("args");
String site = response.getString("site"),
network = response.getString("network");
System.out.println("Site: "+site+"\nNetwork: "+network);
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new com.android.volley.Response.ErrorListener // CHANGES HERE
() {
#Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
}
});
Volley.newRequestQueue(this).add(jsonRequest);

I want to store data requested by android volley to make some processing on data outside the onResponse ,I tried shared preference but it not updated if i have several volley requests.
this.context=context;

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 want to call API Using Volley. There is an Multiple object Request So i don't Know Proper way. I was tried to code as below.But it does not give me Response.So can Anyone help me???
MainActivity
public void getJsonResponsePost(){
JSONObject jsonData = new JSONObject();
JSONObject json = new JSONObject();
/*{"data":{"lang_type":"1","keyword":"","latitude":23.022499999999997,"longitude":72.57139833333333,"category":6}}*/
try {
jsonData.put("data",json);
json.put("lang_type","1");
json.put("keyword","");
json.put("latitude",23.022499999999997);
json.put("longitude",72.57139833333333);
json.put("category",6);
Log.d("TAG",jsonData.toString());
} catch (JSONException e) {
e.printStackTrace();
}
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, url, json, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response)
{
Log.d("String Response :",response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d(" Error getting :",error.toString());
}
});
jsonObjectRequest.setTag(REQ_TAG);
requestQueue.add(jsonObjectRequest);
}
I get the following response
String Response :: {"status":"0","message":"Please pass the language type."}
Can you try this?
try {
json.put("lang_type","1");
json.put("keyword","");
json.put("latitude",23.022499999999997);
json.put("longitude",72.57139833333333);
json.put("category",6);
jsonData.put("data",json);
Log.d("TAG",jsonData.toString());
} catch (JSONException e) {
e.printStackTrace();
}
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, url, jsonData, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response)
{
Log.d("String Response :",response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d(" Error getting :",error.toString());
}
});
im pretty new to Android Studio and I'm trying to build a Get Request using Volley, the Server response is a JsonObject. I tested the code with breakpoints but I wonder why I don't jump into onResponse or why it won't work.
Here's my Code of the Get Method:
public Account GetJsonObject(String urlExtension, String name, Context context) {
String baseURL = "myurl.com/api";
baseURL += urlExtension + "/" + name;
// url will look like this: myurl.com/api/user/"username"
final Account user = new Account("","");
//Account(name, email)
RequestQueue requestQueue;
requestQueue = Volley.newRequestQueue(context);
JsonObjectRequest jsonObject = new JsonObjectRequest(Request.Method.GET, baseURL,null,
new Response.Listener<JSONObject>() {
// Takes the response from the JSON request
#Override
public void onResponse(JSONObject response) {
try {
JSONObject obj = response.getJSONObject("userObject");
String username = obj.getString("Username");
String email = obj.getString("Email");
user.setUsername(username);
user.setEmail(email);
}
catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
});
requestQueue.add(jsonObject);
return user;
}
As #GVillavani82 commented your onErrorResponse() method body is empty. Try to log the error like this
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("ERROR", "Error occurred ", error);
}
}
Make sure that you have the below permission set in AndroidManifest.xml file and the api URL is proper.
<uses-permission android:name="android.permission.INTERNET"/>
And JsonObjectRequest class returns Asynchronous network call class. Modify your code like below.
// remove Account return type and use void
public void GetJsonObject(String urlExtension, String name, Context context) {
....
.... // other stuffs
....
JsonObjectRequest jsonObject = new JsonObjectRequest(Request.Method.GET, baseURL,null,
new Response.Listener<JSONObject>() {
// Takes the response from the JSON request
#Override
public void onResponse(JSONObject response) {
processResponse(response); // call to method
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("ERROR", "Error occurred ", error);
}
});
requestQueue.add(jsonObject);
}
Now create another method like below
private void processResponse(JSONObject response) {
try {
final Account user = new Account("","");
JSONObject obj = response.getJSONObject("userObject");
String username = obj.getString("Username");
String email = obj.getString("Email");
user.setUsername(username);
user.setEmail(email);
} catch (JSONException e) {
e.printStackTrace();
}
}
I'm trying to connect my app with server but getting an error. Please help!
I'm trying to connect my app using volley library to the server,but whenever I try to run my code I get the following error
incompatible types: int cannot be converted to String
I tried changing from String to int, but it didn't help!
show.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, **<-------------error here**
showUrl, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
JSONArray student = response.getJSONArray("student");
for (int i=0;i<student.length();i++){
JSONObject students = student.getJSONObject(i);
String firstname = students.getString("firstname");
String lastname = students.getString("lastname");
String age = students.getString("age");
result.append(firstname+""+lastname+""+age+""+"\n");
}
result.append("==\n");
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
});
requestQueue.add(jsonObjectRequest);
}
});
}
}
Got your problem now.
You're using incorrect method of JsonObjectRequest from Volley.
You're calling this method
JsonObjectRequest(String url, JSONObject jsonRequest, Listener<JSONObject> listener, ErrorListener errorListener)
instead of
JsonObjectRequest(int method, String url, JSONObject jsonRequest,
Listener<JSONObject> listener, ErrorListener errorListener)
where first argument is an int.
You're passing in 4 arguments, so the upper method is being called where your int method is being converted to String url
You can fix it by passing 5 arguments, and all should be good then.
requestQueue = Volley.newRequestQueue(this);
// follow this
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET,
"url", null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
});
requestQueue.add(jsonObjectRequest);
