Problemas de Android JSON CharSet UTF-8

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 resulta en la aparición de algún carácter extraño (por ejemplo, 'Â'). Entiendo que esto tiene que ver con el juego de caracteres, por lo tanto, configuré InputStreamReader en "UTF-8" pero no parece haber resuelto el problema.

       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());
        }

Log.d "línea" da

¿Alguna idea?

¿También ha probado otras codificaciones como "ISO-8859-1"? Resolví un problema al usar esto ... sin embargo, fue para letras acentuadas ... ¿Qué caracteres te están dando este problema? -

Entonces, ¿cuál es exactamente la salida de Log.d ("línea:", línea)? -

Lo siento, olvidé poner el registro de salida (gracias Jens). -

pruebe BufferedReader en = new BufferedReader (nuevo InputStreamReader (tc.getInputStream (), "iso-8859-1"), 8); -

Gracias Scalar por la sugerencia. Desafortunadamente, todavía muestra personajes extraños. -

Pruebe el siguiente fragmento de código que me ayudó cuando tenía un problema similar:

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

¿Por qué tenemos que usar una función tan retorcida? Tiene que estar encerrado en un bloque de captura de prueba. - Bilbo Bolsón

Personalmente, me gusta incluir todo mi análisis json dentro de los bloques try catch por si acaso. - vm204

Sé que esto es un par de años después, pero se me ocurrió una solución más confiable que esta, y no necesita todas las cosas adicionales de codificación.

Esto se encontró por accidente mientras buscaba otra cosa, pero funciona:

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

Lo que hace es 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 agarrar es como una cuerda primero

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 probará que la cadena existe y luego la reemplazará con la versión totalmente codificada

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