How can I parse this json in an android project?
{"code":200,"lang":"en-ru","**text**":["Лучше поздно, чем никогда"]}
I need only a part of "**text**":["Лучше поздно, чем никогда"]


JSONObject jObj = new JSONObject("{"code":200,"lang":"en-ru","text":"Лучше поздно, чем никогда"}");
String text = jObj.optString("text");

Extracting strings out of a String response [duplicate]

How do I parse JSON in Android? [duplicate]

I have following String response. Out of which I want to extract MAC ID & other fields like Version, Type, devIP etc.
Response ={
"Version" : “1.10",
"Type" :"'xyzTYPE",
"MaCID" :"ABCD1F2G3900",
"devIP" : "'192.168.1.100",
"Signal": "-66",
"AreaName" :"'power",
"SubType" :"wifidev",
"'BuiIdTime" : "11:50:47",
"'BuiIdDate": "'Nov 2 2018"
}
Though I have implemented it in this way.
String macID = result.substring(result.indexOf("MaCID")+11,result.indexOf("devIP")-4);
I want to know if there is another sophisticated manner to do the same.

Your response looks like JSON,
so for json response in result;
JSONObject lsubObject= new JSONObject(result);
String MaCID =lsubObject.getString("MaCID");

First visit to http://www.jsonschema2pojo.org/ and create your model classes. (or create manually)
Than use to https://github.com/google/gson library for parsing

Parsing nested JSONObject in Android [duplicate]

In my project, I am getting the following JSON from the HTTP response.
{"base":"USD","date":"2015-04-24","rates":{"AUD":1.2827,"BGN":1.8069,"BRL":2.9733,"CAD":1.2119,"CHF":0.9551,"CNY":6.1948,"CZK":25.364,"DKK":6.8927,"GBP":0.6614,"HKD":7.75,"HRK":7.0284,"HUF":278.53,"IDR":12954.0,"ILS":3.9244,"INR":63.563,"JPY":119.51,"KRW":1078.25,"MXN":15.358,"MYR":3.5741,"NOK":7.8298,"NZD":1.3216,"PHP":44.281,"PLN":3.7076,"RON":4.08,"RUB":51.215,"SEK":8.6674,"SGD":1.3375,"THB":32.55,"TRY":2.7314,"ZAR":12.182,"EUR":0.9239}}
I want to get the "BGN" from the above json. How to get it.

There are multiple steps involved in this
First: Create a jsonObject
JSONObject jObject = new JSONObject(yourJSON_String);
Second: Get your desired Object or Array, in your case
obj = getJSONObject("rates")
Third: Get required String
obj.getString("BGN");
Here is the JSON CLASS REFERENCE

Assuming you are using JSONObject, and that your root document is called "doc",
JSONObject rates = doc.getJSONObject("rates") would get you the rates part:
{"AUD":1.2827,"BGN":1.8069,"BRL":2.9733,"CAD":1.2119,"CHF":0.9551,"CNY":6.1948,"CZK":25.364,"DKK":6.8927,"GBP":0.6614,"HKD":7.75,"HRK":7.0284,"HUF":278.53,"IDR":12954.0,"ILS":3.9244,"INR":63.563,"JPY":119.51,"KRW":1078.25,"MXN":15.358,"MYR":3.5741,"NOK":7.8298,"NZD":1.3216,"PHP":44.281,"PLN":3.7076,"RON":4.08,"RUB":51.215,"SEK":8.6674,"SGD":1.3375,"THB":32.55,"TRY":2.7314,"ZAR":12.182,"EUR":0.9239}
From this object you can then simply get the BGN value using
String bgn = rates.getString("BGN")

JSONObject responseJson = new JSONObject("<your-string">);
JSONObject ratesJson = responseJson.getJSONObject("rates");
double rate = ratesJson.getDouble("BGN");
To see the JSON object clearly, use PrettyJson. Copy paste the JSON string here and it will show you nested objects (if any) for clearly understanding the response.

Android: parsing json file [duplicate]

Parsing JSON file in android

I need to call this URL: https://login.skype.com/json/validator?new_username=name.surname
I obtain a json file format. I need only to take the element associated to tag "status". For the above link is "status":406, so I need the value 406. What is the most simple way for implementing a parser that get only this element?

Simplest way to do it for this particular situation is
JSONObject obj=new JSONObject(myJSONString);
String status=obj.getString("status");
You'll have to handle the JSONException incase the tag "status" isn't found.

Have you got this response as a string yet? That is your first step but as you are asking for a parser I assume youve done this. If so the rest is easy:
String jsonString = parsedString; //The downloaded JSON String
JSONObject firstObj = new JSONObject(parsedString);
String status = firstObj.getString("status");
