JSONObject cannot be converted to JSONArray but after successfully tested - android
I getting this error: JSONObject cannot be converted to JSONArray
caused by this part of code:
private int parse() {
try {
Log.d("Jou", "result");
JSONArray ja = new JSONArray(data);
JSONObject jo = null;
titles.clear();
skills.clear();
for (int i = 0; i < ja.length(); i++) {
jo = ja.getJSONObject(i);
String id = jo.getString("ID");
String title = jo.getString("post_title");
//String content = jo.getString("post_content");
String date = jo.getString("post_date");
Skill skill = new Skill();
skill.setId(id);
skill.setTitle(title);
//skill.setContent(content);
skill.setDate(date);
skills.add(skill);
titles.add(title);
}
return 1;
} catch (JSONException e) {
Log.d("Jou", e.getMessage());
return 0;
}
Although I tried it before and it was exactly the same, then I added another string which is the date then I got the error. What could be wrong with the code?
This is the result from the server that needs to be parsed:
s = {"result":[{"post_id":"390","post_title":"Cart","post_date":"2017-02-07 12:17:29"},{"post_id":"421","post_title":"Front End Developer - Digital Arts","post_date":"2017-02-07 12:18:04"},{"post_id":"431","post_title":"Art Director","post_date":"2017-02-07 12:18:19"}]}
Here is the PHP script:
<?php
$dbhost = 'localhost';
$dbuser = '';
$dbpass = '';
$conn = mysqli_connect($dbhost, $dbuser, $dbpass) or die ("Unable to connect") ;
if(! $conn )
{
echo 'Could not connect: ' . mysqli_error();
}
error_reporting(-1);
ini_set('display_errors', 'On');
mysqli_set_charset($conn, 'utf8');
$search ="";
if(isset($_REQUEST['query'] )){
$search = $_REQUEST['query'];
}
if($search != ""){
$sql = "SELECT ID,post_title,post_date FROM `wp_posts` WHERE post_title LIKE '%".$search."%'";
mysqli_select_db($conn,'');
$query = mysqli_query($conn, $sql ) or die ("Error: ".mysqli_error($conn));;
$result = array();
while($row = mysqli_fetch_array($query, MYSQLI_ASSOC)){
array_push($result,
array('post_id'=>$row['ID'],
'post_title'=>$row['post_title'],
'post_date'=>$row['post_date']
));}
echo json_encode(array("result"=>$result));
}else{
echo 'No search field has been sent';
}
?>
Try following code :
try {
Log.d("Jou", "result");
JSONObject object = new JSONObject(data)
JSONArray ja = object.getJSONArray("result");
JSONObject jo = null;
titles.clear();
skills.clear();
for (int i = 0; i < ja.length(); i++) {
jo = ja.getJSONObject(i);
String id = jo.getString("post_id");
String title = jo.getString("post_title");
//String content = jo.getString("post_content");
String date = jo.getString("post_date");
Skill skill = new Skill();
skill.setId(id);
skill.setTitle(title);
//skill.setContent(content);
skill.setDate(date);
skills.add(skill);
titles.add(title);
}
return 1;
} catch (JSONException e) {
Log.d("Jou", e.getMessage());
return 0;
}
Check with the following code. I hope it will work
private int parse(String data) {
try {
JSONObject jsonObject = new JSONObject(data); //get a response as Json Object and then get it as array by corresponding key
JSONArray ja = jsonObject.getJSONArray("result");
JSONObject jo = null;
for (int i = 0; i < ja.length(); i++) {
jo = ja.getJSONObject(i);
String id = jo.getString("ID");
String title = jo.getString("post_title");
//String content = jo.getString("post_content");
String date = jo.getString("post_date");
Skill skill = new Skill();
skill.setId(id);
skill.setTitle(title);
//skill.setContent(content);
skill.setDate(date);
skills.add(skill);
titles.add(title);
}
return 1;
} catch (JSONException e) {
Log.d("TAG", e.getMessage());
return 0;
}
}
There is some problem in your json response it is taking extra character in post_date try to validate it in the below link.

Android get Index 1 out of range on parse json format
i'm trying to parse this below json format such as:
[
[
{
"mobileNumber":"<Censored>","contactUserId":"17",
"userEwallets":
[
{"accountNumber":"<Censored>"},
{"accountNumber":"<Censored>"},
{"accountNumber":"<Censored>"}
]
}
]
,
[
{
"mobileNumber":"<Censored>","contactUserId":"1",
"userEwallets":
[
{"accountNumber":"<Censored>"}
]
}
]
]
for parsing second json array of that as
[
{
"mobileNumber":"<Censored>",
"contactUserId":"1",
"userEwallets":
[
{"accountNumber":"<Censored>"}
]
}
]
i get this error:
Index 1 out of range [0..1)
from below code my code can only parse the first array of that, for second array i get exception when i try to get mobileNumber of second json array object
for (int i = 0; i < response.length(); i++) {
try {
JSONArray jsonArray = response.getJSONArray(i);
final String mobileNumber = jsonArray.getJSONObject(i).getString("mobileNumber");
final String contactUserId = jsonArray.getJSONObject(i).getString("contactUserId");
final String userEwallets = jsonArray.getJSONObject(i).getString("userEwallets");
Log.e("MobileNumber ", mobileNumber);
JSONArray ewallets = new JSONArray(userEwallets);
for (int j = 0; j < ewallets.length(); j++) {
JSONObject ewalletObject = ewallets.getJSONObject(j);
final String accountNumber = ewalletObject.getString("accountNumber");
Log.e("accountNumber ", accountNumber);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
Try this one...
JSONArray response;
try {
response = new JSONArray(res);
for (int i = 0; i < response.length(); i++) {
JSONArray insideJSONArray = response.getJSONArray(i);
JSONObject jsonObject = insideJSONArray.getJSONObject(0);
String mobileNumber = jsonObject.getString("mobileNumber");
Log.e("TAG", "mobileNumber: " + mobileNumber);
String contactUserId = jsonObject.getString("contactUserId");
Log.e("TAG", "mobileNumber: " + contactUserId);
JSONArray userEwallets = jsonObject.getJSONArray("userEwallets");
for (int j = 0; j < userEwallets.length(); j++) {
JSONObject ewalletObject = userEwallets.getJSONObject(j);
final String accountNumber = ewalletObject.getString("accountNumber");
Log.e("accountNumber ", accountNumber);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
Change:
final String mobileNumber = jsonArray.getJSONObject(i).getString("mobileNumber");
final String contactUserId = jsonArray.getJSONObject(i).getString("contactUserId");
final String userEwallets = jsonArray.getJSONObject(i).getString("userEwallets");
to
final String mobileNumber = jsonArray.getJSONObject(0).getString("mobileNumber");
final String contactUserId = jsonArray.getJSONObject(0).getString("contactUserId");
final String userEwallets = jsonArray.getJSONObject(0).getString("userEwallets");

You are interpreting the json in a wrong way... if you analyse the json chain you will get this: as you can see you have an array inside and array... hope the picture helps you to see it better.
You have to again loop through the jsonArray to get "lf" key value.
Try this...
try {
JSONObject jsonObject = new JSONObject(result);
JSONArray jsonArray = jsonObject.getJSONArray(ITEM_TAG);
for(int i = 0; i < jsonArray.length(); i++) {
JSONObject c = jsonArray.getJSONObject(i);
JSONArray array = c.getJSONArray("lfs");
for(int j=0;j<array.length();j++){
JSONObject obj = array.getJSONObject(j);
String name = obj.getString("lf");
}
}
} catch (Exception e) {

how I can access data from a JSONArray in Android?
how I can access data from a JSONArray? It is this and contains this information:
"deadlines": [
{
"start": 1439539200,
"end": 1439542800
},
{
"start": 1440144000,
"end": 1440147600
},
{
"start": 0,
"end": 0
}
]
I need to have in a String tag each item "start". Thanks
EDIT
My code is this:
JSONArray array = moduleObject.specialForcedConf;
// array = [{"deadlines":[{"start":1439539200,"end":1439542800},{"start":1440144000,"end":1440147600},{"start":0,"end":0}]}]
for (int j=0; j < array.length(); j++)
{
try
{
JSONObject obj = array.getJSONObject(j);
String start = obj.getString("start");
String end = obj.getString("end");
Log.e("", "start = " + start);
}
catch (JSONException e)
{
Log.e("", "error = " + e.getMessage());
}
}
I get this error:
"error = No value for start"
Do this
JSONArray array = moduleObject.specialForcedConf;
// array = [{"deadlines":[{"start":1439539200,"end":1439542800},{"start":1440144000,"end":1440147600},{"start":0,"end":0}]}]
JSONArray jArray = array.getJSONObject(0).getJSONArray("deadlines");
for (int i = 0; i < jArray.length(); i++) // assuming your array is jArray
{
try
{
JSONObject obj = jArray.getJSONObject(i);
String start= obj.getString("start"); // store in an ArrayList
String end = obj.getString("end"); //// store in an ArrayList
}
catch (JSONException e)
{
// Error
}
}
JSONArray mJsonArray=new JSONArray("Deadlines");
for(int i=0;i<mJsonArray.length();i++){
JSONObject mJsonObject=new JSONObject(mJsonArray.get(i).toString));
String start = mJsonObject.optString("start","");
String end = mJsonObject.optString("end","");
}
Try this:
StringBuilder sb = new StringBuilder();
JSONArray arr = new JSONArray("deadlines");
for(int i=0;i<arr.length;i++){
JSONObject obj = arr.getJSONObject(i);
sb.append(obj.get("start").toString());
sb.append(",");
}
String strStartTag = sb;
JSONArray ja = new JSONArray(yourjsondata));
for (int i = 0; i < ja.length(); i++) {
JSONObject jo_feed = new JSONObject(ja.get(i).toString());
String start = jo_feed.getString("start");
}
Nested JSONArray Record Parsing Issue Android
I am making a App which receives a JSON Data From Server, User will select a value from Spinner like 0,1,2... and so on, On the Basis of number selection JSON will return a data from user defined index like 0,1.. i don't know how to parse a inner JSON Data in Android
json = new JSONObject(JSONParser.Result);
JSONArray jArray = json.getJSONArray("data");
StopElement _stop = new StopElement();
Log.d("JSON Algo Result", json.toString());
if (jArray!=null) {
for (int i = 0; i < jArray.length(); i++) {
jsonarray = jArray.getJSONArray(i);
if (jsonarray != null) {
for (int j = 0; j < jsonarray.length(); i++){
if(i==0) {
jsonarray = jArray.getJSONArray(j);
_stop.setName(jsonarray.getString(0));
StopElement.Stop_name_list.add(_stop.getName());
}
}
} else {
break;

I Solved My Issue like this
try {
int count = 0;
if (success == 1) {
json = new JSONObject(JSONParser.Result);
jArray = json.getJSONArray("data");
StopElement _stop = new StopElement();
for (int i = 0; i < jArray.length(); i++) {
count = count + 1;
// Log.d("Counter", String.valueOf(count));
get_path.add(String.valueOf(count));
jsonarray = jArray.getJSONArray(i);
Log.d("path Array", jsonarray.toString());
if (getitemno>0) {
getpath = jArray.getJSONArray(getitemno);
for (int j = 0; j < getpath.length(); j++) {
getresult = getpath.getJSONArray(j);
_stop.setName(getresult.getString(0));
_map.setLat(getresult.getDouble(1));
_map.setLng(getresult.getDouble(2));
StopElement.Stop_name_list.add(_stop.getName());
MapCoordinatesElement.Lat.add(_map.getLat());
MapCoordinatesElement.Lng.add(_map.getLng());
//Log.d("Stop names", _stop.getName());
// Log.d("Index Array", getpath.toString());
}
} else {
getpath = jArray.getJSONArray(0);
for (int j = 0; j < getpath.length(); j++) {
getresult = getpath.getJSONArray(j);
_stop.setName(getresult.getString(0));
_map.setLat(getresult.getDouble(1));
_map.setLng(getresult.getDouble(2));

can't fill array NewsData[] NewsData_data
write Custom ArrayAdapter by example: http://www.ezzylearning.com/tutorial.aspx?tid=1763429&q=customizing-android-listview-items-with-custom-arrayadapter
i can't fill array in cycle.
working example:
Weather weather_data[] = new Weather[]
{ new Weather("http://www.ezzylearning.com/images/ImagesNew/net_framework.png", "Cloudy"),
new Weather("http://www.ezzylearning.com/images/ImagesNew/net_framework.png", "Showers")
};
my code:
NewsData[] NewsData_data;
// build hash set for list view
public void ListDrwaer() {
try {
JSONObject jsonResponse = new JSONObject(jsonResult);
JSONArray jsonMainNode = jsonResponse.optJSONArray("news");
for (int i = 0; i < jsonMainNode.length(); i++) {
JSONObject jsonChildNode = jsonMainNode.getJSONObject(i);
String header = jsonChildNode.optString("header");
String short_text = jsonChildNode.optString("short_text");
String team = jsonChildNode.optString("team");
String datatime = jsonChildNode.optString("datatime");
String photo_url = jsonChildNode.optString("photo_url");
NewsData_data[i] = new NewsData(header, short_text, team, datatime, photo_url);
}
} catch (JSONException e) {
Toast.makeText(getActivity(), "Error" + e.toString(),
Toast.LENGTH_SHORT).show();
}
NewsDataAdapter adapter = new NewsDataAdapter(getActivity(),
R.layout.news_details, NewsData_data);
listView.setAdapter(adapter);
}
You need to initialize this array:
NewsData[] NewsData_data;
// build hash set for list view
public void ListDrwaer() {
try {
JSONObject jsonResponse = new JSONObject(jsonResult);
JSONArray jsonMainNode = jsonResponse.optJSONArray("news");
NewsData_data=new NewsData[jsonMainNode.length()];//<------------HERE
for (int i = 0; i < jsonMainNode.length(); i++) {
JSONObject jsonChildNode = jsonMainNode.getJSONObject(i);
String header = jsonChildNode.optString("header");
String short_text = jsonChildNode.optString("short_text");
String team = jsonChildNode.optString("team");
String datatime = jsonChildNode.optString("datatime");
String photo_url = jsonChildNode.optString("photo_url");
NewsData_data[i] = new NewsData(header, short_text, team, datatime, photo_url);
}
} catch (JSONException e) {
Toast.makeText(getActivity(), "Error" + e.toString(),
Toast.LENGTH_SHORT).show();
}
NewsDataAdapter adapter = new NewsDataAdapter(getActivity(),
R.layout.news_details, NewsData_data);
listView.setAdapter(adapter);
}
Simplified answer: your array is not initialized. Longer answer, you have to know how big it is going to be, then initialize it to that size. A simple example: NewsData[] NewsData_data; ArrayList<NewsData> newsDataArray = new ArrayList<NewsData>(); String header = "header"; String short_text = "short_text"; String team = "team"; String datatime = "datatime"; String photo_url = "photo_url"; newsDataArray.add(new NewsData(header, short_text, team, datatime, photo_url)); newsDataArray.add(new NewsData(header, short_text, team, datatime, photo_url)); NewsData_data = new NewsData[newsDataArray.size()]; newsDataArray.toArray(NewsData_data); System.out.println(NewsData_data);
