Android JSON CharSet UTF-8 problems

Actualmente estoy trabajando en una aplicación de Android, que obtiene sus datos de una API que proporciona datos JSON. Estoy almacenando elementos para los datos JSON como cadenas, lo que hace que aparezca un carácter extraño (por ejemplo, ''). Entiendo que esto tenga que ver con el juego de caracteres, por lo tanto, he establecido InputStreamReader en "UTF-8", pero no parece haber resuelto el problema.Android JSON CharSet UTF-8 problems

 URL hukd = new URL(requestUrl); 
     URLConnection tc = hukd.openConnection(); 
     BufferedReader in = new BufferedReader(new InputStreamReader(tc.getInputStream(), "UTF-8")); 
     String line = in.readLine(); 
     Log.d("line :", line); 
     JSONObject obj = new JSONObject(line); 
     JSONArray ja = obj.getJSONObject("deals").getJSONArray("items"); 
     for (int i = 0; i < ja.length(); i++) { // each deal 
      JSONObject jo = (JSONObject) ja.get(i); 
      // make the deal 
      Deal d = new Deal(jo.getString("title"), 
        jo.getString("description"), 
        jo.getString("price"),jo.getString("temperature"), 
        jo.getJSONObject("merchant").getString("name"), 
        jo.getString("deal_image"), 
        jo.getString("deal_image_highres")); 
      listItems.add(d); 
      Log.d("Deal:", d.toString()); 
     }

¿Alguna idea?

¿Has probado también otras codificaciones como "ISO-8859-1"? Resolví un problema usando esto ... sin embargo, fue para letras acentuadas ... ¿Qué personajes te están dando estos problemas? – thermz

¿Cuál es exactamente la salida de Log.d ("línea:", línea)? – Jens

Lo siento, olvidé de poner la salida de registro (gracias Jens). – bencallis

intente lo siguiente fragmento de código que me ayudó cuando estaba teniendo un problema similar:

new String(jo.getString("name").getBytes("ISO-8859-1"), "UTF-8");

Muchas gracias. ¡Esto funciona! – bencallis

¿por qué tenemos que usar una función tan retorcida? Tiene que estar encerrado en un bloque try catch. –

Personalmente, me gusta adjuntar todos mis análisis JSON dentro de los bloques de captura de prueba por si acaso. – vm204

Sé que esto es un par de años después, pero yo he llegado con una solución más fiable que esta uno, y que no necesita toda la codificación de material extra

este fue encontrado por accidente mientras estaba buscando otra cosa, pero funciona:

"" + jo.opt("name");

lo que esto hace i s obtener el resultado como un objeto sin formato, y ponerlo al final de una cadena vacía lo fuerza a un formato de cadena; por supuesto, si la entrada no era originalmente una cadena, puede dar resultados oscuros, así que tal vez intente agarrarla como una primera cadena

tengo algo como esto:

String s = ""; 
try { 
    s = jo.getString("name"); 
    s = "" + jo.opt("name"); 
} catch (Exception e) { 
    Log.e("JSON error", "error:" + e.toString()); 
}

esto pondrá a prueba existe la cadena, y luego reemplazarlo con la versión totalmente codificada

espero que esto ayude a alguien en el futuro :-)
