I want to get two json array from remote url
I am using AsyncTask to do that but i can't get any data !
#Override
protected Void doInBackground(String... params) {
try {
// Creating JSON Parser instance
JSONParser jParser = new JSONParser();
// getting JSON string from URL
String json = jParser.getJSONFromUrl(params[0]);
// Getting Array of Contacts
data = new JSONArray(json);
JSONArray cities = data.getJSONArray();
// looping through All cities
for (int i = 0; i < cities.length(); i++) {
JSONObject e = cities.getJSONObject(i);
String ci_name = e.getString("ct_name");
String ci_web_id = e.getString("ct_id");
db.addCity(ci_name, ci_web_id);
db.closeDatabase();
}
JSONArray districts = data.getJSONArray(1);
// looping through All districts
for (int i = 0; i < districts.length(); i++) {
JSONObject e = districts.getJSONObject(i);
String di_name = e.getString("ar_name");
String di_web_id = e.getString("ar_id");
db.addDistrict(di_name, di_web_id);
db.closeDatabase();
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
The return data is like that :
{"city":[
{"ct_id":"1432","ct_name":"\u062e\u0645\u064a\u0633 \u0645\u0634\u064a\u0637","ct_hide":"0","ct_ord":"0","ct_created":"0"},
{"ct_id":"1434","ct_name":"\u0639\u0633\u064a\u0631","ct_hide":"0","ct_ord":"0","ct_created":"0"},{"ct_id":"1435","ct_name":"\u0627\u0644\u0645\u0646\u0637\u0642\u0629 \u0627\u0644\u0634\u0631\u0642\u064a\u0629","ct_hide":"0","ct_ord":"0","ct_created":"0"}
], "area":[
{"ar_id":"1422","ar_name":"\u0627\u0644\u0645\u062f\u064a\u0646\u0629 \u0627\u0644\u0645\u0646\u0648\u0631\u0647","ar_hide":null,"ar_ord":null,"ar_created":null}, {"ar_id":"1433","ar_name":"\u0646\u062c\u0631\u0627\u0646","ar_hide":null,"ar_ord":null,"ar_created":null}]
}
Your json is a JSONObject not a JSONarray.
This
data = new JSONArray(json);
is wrong.
{ // json object node
"city": [ // json array city
{ // json object
"ct_id": "1432",
"ct_name": "خميس مشيط",
"ct_hide": "0",
"ct_ord": "0",
"ct_created": "0"
},
{
"ct_id": "1434",
"ct_name": "عسير",
"ct_hide": "0",
"ct_ord": "0",
"ct_created": "0"
},
{
"ct_id": "1435",
"ct_name": "المنطقة الشرقية",
"ct_hide": "0",
"ct_ord": "0",
"ct_created": "0"
}
],
"area": [ // json array area
{
"ar_id": "1422",
"ar_name": "المدينة المنوره",
"ar_hide": null,
"ar_ord": null,
"ar_created": null
},
{
"ar_id": "1433",
"ar_name": "نجران",
"ar_hide": null,
"ar_ord": null,
"ar_created": null
}
]
}
To parse
JSONObject jb = new JSONObject(json);
JSONArray city = jb.getJSONArray("city");
for(int i=0;i<city.length();i++)
{
JSONObject jb1 = city.getJSONObject(i);
String id = jb1.getString("ct_id");
String name = jb1.getString("ct_name");
String hide = jb1.getString("ct_hide");
String ord = jb1.getString("ct_ord");
String created = jb1.getString("ct_ord");
Log.i("city id is",id);
}
JSONArray area = jb.getJSONArray("area");
for(int i=0;i<area.length();i++)
{
JSONObject jb1 = area.getJSONObject(i);
String id = jb1.getString("ar_id");
String name = jb1.getString("ar_name");
String hide = jb1.getString("ar_hide");
String ord = jb1.getString("ar_ord");
String created = jb1.getString("ar_ord");
Log.i("Area id is",id);
}
You could also consider using gson to parse json to java objects
http://code.google.com/p/google-gson/
I don't see any request to remote url. How do you get data from your server?
Generally, it looks like this:
public void execute() {
final AndroidHttpClient client = AndroidHttpClient.newInstance("TAG");
try {
HttpUriRequest request = getRequest();
HttpResponse response = client.execute(request);
final int code = response.getStatusLine().getStatusCode();
Log.d("TAG", "Server returns " + code);
if (code == HttpStatus.SC_OK) {
String json = EntityUtils.toString(response.getEntity());
handleResult(json);
}
} catch (IOException e) {
Log.e("TAG", "Failed to execute response", e);
}
}
private void handleResult(String json) {
try {
JSONObject jObject = new JSONObject(json);//your response is not an array
JSONArray content = jObject.getJSONArray("city")
final int count = content.length();
for (int i = 0; i < count; i++) {
JSONObject city = content.getJSONObject(i);
Log.d("TAG", city.getString("ct_id"));
}
} catch (JSONException e) {
Log.e("TAG", "Failed to obtain json", e);
}
}

}
}
}
}
this is the code I tried :
public void getJSON(final String city) throws JSONException {
new AsyncTask<Void, Void, Void>() {

}
#Override
protected Void doInBackground(Void... params) {

new BufferedReader(new InputStreamReader(connection.getInputStream()));
StringBuffer json = new StringBuffer(1024);
String tmp = "";
while ((tmp = reader.readLine()) != null) {
json.append(tmp).append("\n");

try {

System.out.println("Temp Value : "+" : ");
runOnUiThread(new Runnable() {
#Override
public void run() {
textvw.setText("");
}
});
} catch (Exception e) {
Log.e("GetFeedTask", "Error:" + e.getMessage());
}
}
}
}.execute();
}
The exception is because the response does not contain JSON Array. Change your
JSONArray pagesArray = forecastArray.getJSONArray("pages");
to
JSONObject pagesArray = forecastArray.getJSONObject("pages");
and I believe that you're trying to get keys which are dynamic. You cloud get the objects using JSONObject.getKeys() like below.
Iterator keys = pagesArray.keys();
while(keys.hasNext()) {
String dynamicKey = (String)keys.next();
JSONObject jObj = pagesArray.getJSONObject(dynamicKey);
//Get other attributes by jObj.getString() method.
}
Try and let me know if it works.
The error is clear enough. you try to assign a JSONobject to a JSONArray
JSONArray pagesArray = forecastArray.getJSONArray("pages");
Replace by
JSONObject pagesArray = forecastArray.JSONObject("pages");
the data of a JSONArray are between [] and not {}.
your error is in :
JSONArray pagesArray = forecastArray.getJSONArray("pages");
Your problem is that you getJSONArray while pages are a JsonObject in your data .if your "pages" is a array in your data you must send it in [] from server like this:
{
"batchcomplete": "",
"query": {
"pages": [ {
"pageid": 25675557,
"ns": 0,
"title": "Cricket",
"extract": "Cricket is a bat-and-ball game played between two teams of eleven players each on a cricket field, at the centre of which is a rectangular 22-yard-long (20 metres) pitch with a target at each end called the wicket (a set of three wooden stumps upon which two bails sit). "
},
{
"pageid": 25675557,
"ns": 0,
"title": "Cricket",
"extract": "Cricket is a bat-and-ball game played between two teams of eleven players each on a cricket field, at the centre of which is a rectangular 22-yard-long (20 metres) pitch with a target at each end called the wicket (a set of three wooden stumps upon which two bails sit). "
}
]
}
}
and in android :
try {
//JSONObject forecastJson = new JSONObject(data);
JSONObject forecastArray = data.getJSONObject("query");
System.out.println(forecastArray);
JSONArray pagesArray = forecastArray.getJSONArray("pages");
System.out.println(pagesArray);
for (int k = 0; k < pagesArray.length(); k++) {
try {
JSONObject object = pagesArray.getJSONObject(k);
String pageid = object.getString("pageid");
String ns = object.getString("ns");
String title = object.getString("title");
String extract = object.getString("extract");
} catch (JSONException e) {
e.printStackTrace();
}
}
} catch (Exception e) {
Log.e("GetFeedTask", "Error:" + e.getMessage());
}
I would need help to parse this JSONArray in my Android app. I'm a bit confused with JSONObjects and JSONArrays :
[
{
"nid": [
{
"value": "3"
}
],
"uid": [
{
"target_id": "1",
"url": "/user/1"
}
],
"field_image": [
{
"target_id": "2",
"alt": "alternate 1",
"title": "",
"width": "640",
"height": "640",
"url": "http://url"
},
{
"target_id": "3",
"alt": "alternate 2",
"title": "",
"width": "640",
"height": "640",
"url": "http://url"
}
]
}]
Here is what I've got to start the iteration :
public void onResponse(JSONArray response) {
try {
jsonResponse = "";
for (int i = 0; i < response.length(); i++) {
...
Here is your code to parse data,
private void parseData(){
try {
JSONArray jsonArray=new JSONArray(response);
JSONObject jsonObject=jsonArray.getJSONObject(0);
JSONArray jsonArrayNid=jsonObject.getJSONArray("nid");
JSONArray jsonArrayUid=jsonObject.getJSONArray("uid");
JSONArray jsonArrayField_image=jsonObject.getJSONArray("field_image");
for(int i=0;i<jsonArrayNid.length();i++){
JSONObject jsonObjectNid=jsonArrayNid.getJSONObject(i);
String value=jsonObjectNid.getString("value"); //here you get your nid value
}
for(int i=0;i<jsonArrayUid.length();i++){
JSONObject jsonObjectUid=jsonArrayUid.getJSONObject(i);
String target_id=jsonObjectUid.getString("target_id"); //here you get your uid target_id value
String url=jsonObjectUid.getString("url"); //here you get your uid url value
}
for(int i=0;i<jsonArrayField_image.length();i++){
JSONObject jsonObjectFieldImage=jsonArrayField_image.getJSONObject(i);
String target_id=jsonObjectFieldImage.getString("target_id");
String alt=jsonObjectFieldImage.getString("alt");
String title=jsonObjectFieldImage.getString("title");
String width=jsonObjectFieldImage.getString("width");
String height=jsonObjectFieldImage.getString("height");
String url=jsonObjectFieldImage.getString("url");
}
} catch (JSONException e) {
e.printStackTrace();
}
}
for (int i = 0; i < response.length(); i++) {
JSONObject tobject = response.getJSONObject(i);
JSONArray nid = tobject.getJSONArray("nid");
JSONArray uid= tobject.getJSONArray("uid");
JSONArray field_image= tobject.getJSONArray("field_image");
//similarly you can loop inner jsonarrays
}
Use code according to you:
JSONArray array = null;
try {
array = new JSONArray(url); // your web url
JSONObject object = array.getJSONObject(0);
JSONArray array1 = object.getJSONArray("nid");
JSONObject object1 = array1.getJSONObject(0);
String value = object1.getString("value");
JSONArray array2 = object.getJSONArray("uid");
JSONObject object2 = array2.getJSONObject(0);
String target = object2.getString("target_id");
String url = object2.getString("url");
JSONArray array3 = object.getJSONArray("field_image");
JSONObject object3 = array3.getJSONObject(0);
String alt = object3.getString("alt");
Toast.makeText(Testing.this,value+"\n"+target+"\n"+url+"\n"+alt,Toast.LENGTH_LONG).show();
} catch (JSONException e) {
e.printStackTrace();
}
Try to parse like this.
In this code, jsonArray is the parent array which you have in your JSON.
for(int i=0;i<jsonArray.length();i++)
{
try {
JSONObject object=jsonArray.getJSONObject(i);
JSONArray imageArray=object.getJSONArray("field_image");
for(int j=0;j<imageArray.length();j++)
{
JSONObject imageObject=imageArray.getJSONObject(j);
String targetId=imageObject.getString("target_id");
}
}
catch (JSONException e) {
e.printStackTrace();
}
}
Now :) if you have to parse something first look for some library:
http://www.java2s.com/Code/Jar/g/Downloadgson222jar.htm
Download gson.jar and then create java classes that mimic your desired json:
class C1{
private String value;
}
class C2{
private String target_id;
private String url;
}
class C3{
private String target_id;
private String alt;
private String title;
private String width;
private String height;
private String url;
}
class c4{
private List<C1> nid;
private List<C2> uid;
private List<C3> field_image;
}
Since you receive array from C4, you parse it like this:
public void onResponse(JSONArray response){
String value = response.toString();
GsonBuilder gb = new GsonBuilder();
Type arrayType = new TypeToken<List<C4>>() {}.getType();
List<C4> data = gb.create().fromJson(value, arrayType);
}
So in just 3 lines of code, you have your entire json serialized to java objects that you can use in your code.
Try
public void onResponse(JSONArray response) {
try {
if (response != null) {
for (int i = 0; i < response.length(); i++) {
JSONObject jsonObject = resultsArray.getAsJsonObject(i);
//get nid array
JSONArray nidJSONArray = jsonObject.getJSONArray("nid");
//get uid array
JSONArray uidJSONArray = jsonObject.getJSONArray("uid");
//get field_image array
JSONArray fieldImageJSONArray = jsonObject.getJSONArray("field_image");
//parse nid array
if (nidJSONArray != null) {
for (int i = 0; i < nidJSONArray.length(); i++) {
JSONObject jsonObject = nidJSONArray.getAsJsonObject(i);
String value = jsonObject.getString("value");
}
}
//parse uid array
if (uidJSONArray != null) {
for (int i = 0; i < uidJSONArray.length(); i++) {
JSONObject jsonObject = uidJSONArray.getAsJsonObject(i);
String targetId = jsonObject.getString("target_id");
String url = jsonObject.getString("url");
}
}
//parse field_image array
if (fieldImageJSONArray != null) {
for (int i = 0; i < fieldImageJSONArray.length(); i++) {
JSONObject jsonObject = fieldImageJSONArray.getAsJsonObject(i);
String targetId = jsonObject.getString("target_id");
String alt = jsonObject.getString("alt");
String title = jsonObject.getString("title");
String width = jsonObject.getString("width");
String height = jsonObject.getString("height");
String url = jsonObject.getString("url");
}
}
}
}
} catch(Exception e) {
Log.e("Error", e.getMessage());
}
}

Just as your logcat reads org.json.JSONException: Value result of type java.lang.String cannot be converted to JSONObject
Log the response you are getting without parsing the data first. Then you may find out what data types you are dealing with eg: Strings, Integers, Floats,etc.
Post the response here for more help.
EDIT:
This line here jsonObj = new JSONObject("result");
Do this instead jsonObj = new JSONObject(result);
EDIT:
jsonObj = new JSONObject(result);
JSONObject obj = jsonObj.getJSONObject("race");
String id = obj.getString("id");
//do the same for all objects inside race
This question already has an answer here:
JSON array parsing in android
(1 answer)
Closed 7 years ago.
I have a JSON response in this format:
{
"success": true,
"categories": [{
"id": "774",
"name": "1"
}, {
"id": "774",
"name": "1"
}]
}
And I am parsing it like this:
try {
JSONObject obj = new JSONObject(response);
String success = String.valueOf(obj.getBoolean("success"));
JSONArray arr = obj.getJSONArray("categories");
//loop through each object
for (int i=0; i<arr.length(); i++) {
JSONObject jsonProductObject = arr.getJSONObject(i);
String name = jsonProductObject.getString("name");
String url = jsonProductObject.getString("id");
Toast.makeText(getApplicationContext(),name, Toast.LENGTH_LONG).show();
}
} catch (JSONException e) {
e.printStackTrace();
}
But I only get the value of success. What I'm doing wrong here?
Parse as below -
JSONObject obj = new JSONObject(json);
String success = obj.getString("success");
JSONArray arr = obj.getJSONArray("categories");
//loop through each object
for (int i=0; i<arr.length(); i++) {
JSONObject jsonProductObject = arr.getJSONObject(i);
String name = jsonProductObject.getString("name");
String url = jsonProductObject.getString("id");
}
correct json key
JSONArray arr = obj.getJSONArray("checkouts");
replace by:
JSONArray arr = obj.getJSONArray("categories");
DO like this,
if (!result.equalsIgnoreCase("")) {
try {
JSONObject _jsonObject = new JSONObject(result);
boolean json = false;
json = _jsonObject.getBoolean("Status");
JSONArray jsonArray1 = _jsonObject.getJSONArray("categories");
for (int i=0; i<jsonArray1.length(); i++) {
JSONObject jsonObject = jsonArray1.getJSONObject(i);
String name = jsonObject.getString("name");
String id = jsonObject.getString("id");
}
} catch (Exception e) {
Utils.printLoge(5, "error parse json", "--->" + e.getMessage());
return "ERROR";
}
}
I am geting JSON data getting from web service. Below is my code.
How can I decode the json data?
{
"response": [
{
"last_name": "Test",
"id": 279711390,
"first_name": "Vishnu",
"sex": 2,
"photo_50": "https://vk.com/images/camera_50.gif"
}
]
}
How can I parse it? Thanks.
You can keep a POJO class. With the data which you are about to get from server. And parse them and save in that object.
Example:
JSONObject json= new JSONObject(responseString); //your response
try {
JSONArray responseArray = jsonObj.getJSONArray("response");
for (int i = 0; i < responseArray.length(); i++) {
// get value with the NODE key
JSONObject obj = responseArray.getJSONObject(i);
String lastName = obj.getString("last_name");
String firstName = obj.getString("first_name");
//same for all other fields in responseArray
MyResponse myResp = new MyResponse();
myResp.setFirstName(firstName);
myResp.setLastName(lastName);
//set all other Strings
//lastly add this object to ArrayList<MyResponse> So you can access all data after saving
}
}
catch (JSONException e) {
e.printStackTrace();
}
POJO Class:
public class MyResponse{
public String firstName="";
public String lastName="";
//all other fields and getter setters
}
Hope this helps.
You can parse JSON using this code:
str="<The Json>"
try {
JSONObject jObject=new JSONObject(str);
JSONArray menuObject = new JSONArray(jObject.getString("response"));
String lastName;
for (int i = 0; i<menuObject.length(); i++) {
lastName=menuObject.getJSONObject(i).getString("last_name").toString();
...
}
catch (JSONException e) {
e.printStackTrace();
}
Use this code :-
String string = "Your Json"
try {
JSONObject jsonObject=new JSONObject(str);
JSONArray menuObject = new JSONArray(jObject.getJsonArray("response"));
//no need of for loop because you have only one object in jsonArray.
JSONObject oject = menuObject.getJSONObject(0);
String lastName = object.getString("last_name");
String firstName = object.getString("first_name");
Log.d("User Name", firstName + " " + lastName);
catch (JSONException e) {
e.printStackTrace();
}
