I get the date and call the exchangeDataTraFormat 

 private void makeJsonObjReq(){
    showProgressDialog();
    int id = ((AppController) this.getApplication()).getID();
    JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.GET,
            Const.URL_JSON_ARRAY_Editar_USU+"/"+id, null,
            new Response.Listener<JSONObject>() {

                @Override
                public void onResponse(JSONObject response) {
                    Log.d(TAG, response.toString());
                //    hideProgressDialog();
                    JSONObject jsonobj = null;
                    int aJsonint = 0;
                    String aJsonString;
                    try {
                        jsonobj = new JSONObject(String.valueOf(response));
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }

                    try {

                        //String dataresp = trocaFormatoDataTra(jsonobj.getString("nascimento"));
                        String dataresp = trocaFormatoDataTra(jsonobj.getString("nascimento"));
                        JsonNome = jsonobj.getString("nome");
                        JsonNascimento = dataresp;

                        //ADD VALORES CAMPOS
                        NomeTraEd.setText(JsonNome);
                        NascimentoTraEd.setText(JsonNascimento);


                    } catch (JSONException e) {
                        e.printStackTrace();
                    }

                }
            }, new Response.ErrorListener() {

        @Override
        public void onErrorResponse(VolleyError error) {
            VolleyLog.d(TAG, "Error: " + error.getMessage());
            hideProgressDialog();
        }
    });
    // Adding request to request queue
    AppController.getInstance().addToRequestQueue(jsonObjReq,
            tag_json_obj);

}

I have the following method 

 public String trocaFormatoDataTra(String data) {
  //data recebe Dec 31, 1969 12:00:00 AM
    String formatoDeEntrada = "MMM dd, yyyy h:mm:ss";
    String formatoDeSaida = "dd/MM/yyyy";
    SimpleDateFormat dateFormatEntrada = new SimpleDateFormat(formatoDeEntrada);
    SimpleDateFormat dateFormatSaida = new SimpleDateFormat(formatoDeSaida);

    Date dataOriginal = null;
    String dataTrocada = null;

    try {
        //Transforma a String em Date
        dataOriginal = dateFormatEntrada.parse(data);
        //Transforma a Date num String com o formato pretendido
        dataTrocada = dateFormatSaida.format(dataOriginal);
    } catch (ParseException e) {
        //Erro se não foi possível fazer o parse da Data
        e.printStackTrace();
    }
    return dataTrocada;
}

Error logcat

This type of error is common when using conversion functions whose behavior depends on Locale (language / country combination).

The SimpleDateFormat class, when built with the constructor that accepts only a string , uses Locale as the one that is defined on the device.

In this case, the device that is running the code must be set to use Locale pt_BR or pt_PT .

The problem arises because we are trying to convert a date that has the months in English using the class configured to use Portuguese.

The SimpleDateFormat class has another constructor that also receives a Locale . Passing the Locale indicates which rules the SimpleDateFormat should use.

In this case instead of using 

new SimpleDateFormat(formatoDeEntrada)

We should use 

new SimpleDateFormat(formatoDeEntrada, Locale.US)
