Я разбираюсь в JSON для моего приложения для Android, но я не могу получить данные, я заблокирован, я не вижу своей проблемы, кто-нибудь может мне помочь? Это мой код, в журнале кошке я получаю сообщение «Нет значения для ticket_price»not results parsing json

private class DownloadJSON extends AsyncTask<Void, Void, Void> {

        mProgressDialog.setMessage("Actualizando..."); 
        mProgressDialog.setIndeterminate(false);

Это может быть просто, что ваши данные не имеет «ticket_price» для некоторых концертов. В этом случае вы можете рассмотреть optString

Вы можете быстро изучить свой json в функции консоли Javascript в большинстве браузеров.

Просто вставьте ваш JSON в var

var str = {"your_json" : "here"}

Затем вы можете сделать что-то вроде этого ..

for (var gig in str.response.gigs){   
    console.log(str.response.gigs[gig].ticket_price); 
}

И увидеть некоторые результаты, как этот

Object {min: 16, max: 16} 
undefined 
Object {min: 22, max: 52.74} 
Object {min: 15, max: 15} 
Object {min: 8, max: 8} 
Object {min: 120, max: 120} 
Object {min: 15, max: 15} 
Object {min: 10, max: 10} 
Object {min: 12, max: 12}

В Кроме того, вы можете рассмотреть возможность r методов разбора Json. Например, Converting JSON to Java
