Как использовать API геокодирования (JSON) в android?

Я новичок в использовании данных json и смущен тем, как получить то, что я хочу от данных геокодирования. То, что я пытаюсь сделать, это получить название города и состояние с координатами широты и долготы пользователя. Вот некоторые примеры данных:Как использовать API геокодирования (JSON) в android?

Я думаю, вам нужно только formatted_address значение в данном JSON, поэтому попробуйте этот

    try { 
         JSONObject jsonObject = new JSONObject(resultantJSONString); 
         if (jsonObject.getString("status").equals("OK")) { 
          jsonObject = jsonObject.getJSONArray("results") 
            .getJSONObject(0); 
          String formattedAddress = jsonObject.getString("formatted_address"); 
         } 
        } catch (Exception e) { 
         e.printStackTrace(); 
        }

Спасибо. Это .getJSONObject (0) - это то, о чем я забыл. – Jake

Cool..glad, чтобы помочь вам :) –

Фактически это данные геокодирования.
