how to send json array in android retrofit?

I can't send json array to server. When I test in postman raw, it is ok, success return.
Postman Raw;
[
{
"product_id": 2,
"name": "Umbrella",
"price": 200,
"quantity": 1,
"totalprice": 200,
"user_id": 1
},
{
"product_id": 1,
"name": "Apple",
"price": 200,
"quantity": 1,
"totalprice": 200,
"user_id": 1
}
]
APIInterface;
#POST("example/api/order")
Call<JSONArray> postOrder(#Body JSONArray jsonArray);
CartActivity;
try {
JSONArray jsonArray = new JSONArray();
for (Cart cart : cartList) {
JSONObject jsonObject = new JSONObject();
jsonObject.put("product_id", cart.getProduct_id());
jsonObject.put("name", cart.getName());
jsonObject.put("price", cart.getPrice());
jsonObject.put("quantity", cart.getQuantity());
jsonObject.put("totalprice", cart.getTotalprice());
jsonObject.put("user_id", cart.getUser_id());
jsonArray.put(jsonObject);
}
Log.e("JSONArray", String.valueOf(jsonArray));
} catch (JSONException jse) {
jse.printStackTrace();
}
Log;
E/JSONArray: [{"product_id":1,"name":"Umbrella","price":200,"quantity":1,"totalprice":200,"user_id":1},{"product_id":2,"name":"Apple","price":89,"quantity":1,"totalprice":89,"user_id":1}]
Error Message from server;
{"values":[{"nameValuePairs":{"product_id":1,"name":"Umbrella","price":200,"quantity":1,"totalprice":200,"user_id":1}},{"nameValuePairs":{"product_id":2,"name":"Apple","price":89,"quantity":1,"totalprice":89,"user_id":1}}]}

You can directly send the array of objects as parameter. Retrofit will handle the conversion. Change your interface method like this:
#POST("example/api/order")
Call<JSONArray> postOrder(#Body List<Cart> cartList);
Check this link, you will get an idea.

send like this:-
#POST("example/api/order")
Call<JSONArray> postOrder(#Query ("data") JSONArray jsonArray);

Thank in Advance

If you just want to get status, try like this:
JSONObject jsonObject = new JSONObject(jsonString);
String status = jsonObject.optString("status");
if you want to parse whole data, I would recommend you to use Gson.

For easy JSON parsing/manipulating/etc use GSON library at android. Example you can make custom objects and straight create new instance of your custom object from parsing and then just check fields or whatever you need to do.
CustomObject object= gson.fromJson(JSON, CustomObject.class);
if(object.bannerPath != null) {
//Do something
}
Here is the GSON in Github
and here for GSON tutorial

//editing Rohit Arya Code little bit
JSONObject jsonObject = new JSONObject(jsonString);
String status = jsonObject.optString("status");
if(status.equalIgnorecase("400")){
try {
JSONObject jsonObject=new JSONObject("yourResponse");
jsonObject1=jsonObject.getJSONObject("response");
JSONArray jsonArray=jsonObject1.getJSONArray("data");
JSONObject jsonObject2;
for(int i=0;i<jsonArray.length();i++){
JSONObject c = jsonArray.getJSONObject(i);
String banner_name=c.getString("banner_name");
Log.e("banner_name",banner_name);
}
} catch (JSONException e) {
e.printStackTrace();
}
}else{
// don't download
}

Android JSON org.json.JSONEXCEPTION: No Value for ""

I am trying to use Android get the SpeedLimit value from a JSON server response (HERE API - http://route.st.nlp.nokia.com/routing/6.2/getlinkinfo.json?waypoint=52.5308,13.3846&app_id=your_app_id&app_code=your_app_code):

},

"City": "Berlin",

}
}
]
}
}
Here is the code I'm using the get the result out of the JSON:
try {
JSONObject response = new JSONObject(jsonResult);
JSONObject test = response.getJSONObject("Link");
String test1 = test.getString("SpeedLimit");
Toast.makeText(getApplicationContext(), test1,
Toast.LENGTH_SHORT).show();
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "Error" + e.toString(),
Toast.LENGTH_SHORT).show();
}
I keep getting the following exception:
org.json.JSONEXCEPTION: No Value for Link
I must be asking for the wrong information within the JSON but I can't seem to work this one out.
Thank you everyone!

Link JSONArray is inside Response JSONObject instead of in root JSONObject.
So, first need to get Response JSONObject from response then get Link JSONArray:
// Response JSONObject
JSONObject responseJSONObject = response.getJSONObject("Response");
// get Link JSONArray from responseJSONObject
JSONArray linkJSONArray = responseJSONObject.getJSONArray("Link");

The "Link" is a JSONArray instead of JSONObject.
So the code should be :
try {
JSONObject response = new JSONObject(jsonResult);
JSONArray test = response.optJSONArray("Link");
if (test != null && test.length() > 0) {
JSONObject test = test.optJSONObject(0);
if( test != null) {
String test1 = test.getString("SpeedLimit");
Toast.makeText(getApplicationContext(), test1, Toast.LENGTH_SHORT).show();
return;
}
}
Toast.makeText(getApplicationContext(), "No speed limitation data found", Toast.LENGTH_SHORT).show();
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "Error" + e.toString(), Toast.LENGTH_SHORT).show();
}
You also need to consider the situation that there are more than 1 JSONObject included in the Link JSONArray.

Retrieve values from notification using JSON PAYLOAD android

I am in a situation , where my webservice sends me notification which includes
{
"apiKey": "xxxxx-xxx-xxx-xxxx-xxxxxxx",
"appKey": "xxxxx-xxx-xxx-xxxx-xxxxxxx",
"sendAll": true,
"content": {
"subject": "Test Lottery",
"message": "Notification Msg",
"action": {
"type": "DEFAULT",
"data": "url|intent|...",
"labe": "label"
},
"payload": "{'uid':'1','type':'LD'}",
"sound": "default.caf",
"badge": "+1"
}
}
On click of the notification which appeared on top , I need to get the uid and type
I am using Xtify for push notification.....

Try This..
String JSON ="YOUR JSON RESULT STRING";
try {
JSONObject jsonresult = new JSONObject(JSON);
String apiKey= jsonresult.getString("apiKey");
String appKey= jsonresult.getString("appKey");
boolean sendAll= jsonresult.getBoolean("sendAll");
JSONObject contentObject = jsonresult.getJSONObject("content");
String subject= jsonresult.getString("subject");
String message= jsonresult.getString("message");
String sound= jsonresult.getString("sound");
String badge= jsonresult.getString("badge");
JSONObject actionObject = jsonresult.getJSONObject("action");
String type= jsonresult.getString("type");
String data= jsonresult.getString("data");
String labe= jsonresult.getString("labe");
JSONObject payloadObject = jsonresult.getJSONObject("payload");
// do your code..
}
} catch (JSONException e) {
e.printStackTrace();
//catching exceptions if any...
}

I hope this code can help u

parseForcitydetail1(jsonobject.getString("HotelInformationResponse"));
return response;
}catch (Exception e) {
return "\"" + "Access Denied" + "\"";
}
}
public static void parseForcitydetail1(String res){
try{
JSONArray jsonarray1 = new JSONArray(res);
for(int i=0;i<jsonarray1.length();i++){

Hotal_ID.add(jsonobject.getString("#hotelId"));
customer_ID.add(jsonobject.getString("customerSessionId"));
}
parseForcitydetail2(jsonobject.getString("HotelSummary"));
}catch (Exception e) {
System.out.println(e.toString());
}
}
public static void parseForcitydetail2(String res){
try{
JSONArray jsonarray1 = new JSONArray(res);
for(int i=0;i<jsonarray1.length();i++){
JSONObject jsonobject = jsonarray1.getJSONObject(i);
Order.add(jsonobject.getString("#order"));
hote_ID.add(jsonobject.getString("hotelId"));

}
This Same process with "HotelDetails" Parsing
Enjoy !

You may use JSONArray and JSONObject to parse it manually. but its boring and may require extra attention to keys while running in loops. The easiest and highly recommended way is to use Google Gson library to handle this automatically.

Using JSONOBject, JSONArray to contain data like JSONObject, JSONArray
Using methods like: getJSONObject(), getString(), getXXX(). . to get data which you want.
with XXX - data type like int, string
You will understand how to parse JSON in Android easily with the link which describes how to parse JSON clearly (Example):
http://www.technotalkative.com/android-json-parsing/

private JSONObject jObject;
jObject = new JSONObject(your response as string);
//this will give you json object for HotelInformationResponse
JSONObject menuObject = jObject.getJSONObject("HotelInformationResponse");
by this way you can get values
String hotelId = menuObject.getString("#hotelId");
String customerSessionId = menuObject.getString("customerSessionId");
//...rest are same do same thing for HotelDetails
