  NumberFormat numberFormat = NumberFormat.getCurrencyInstance(new Locale("en","IN"));

        if (type1!=null && type2!=null){
            if( rates.containsKey(type1) && rates.containsKey(type2)) {
                Double rate1 = rates.getOrDefault(type1,1.00);
                Double rate2 = rates.getOrDefault(type2,1.00);
                double inp1 = Double.parseDouble(edt1.getText().toString());
                result = (rate2 / rate1) *  inp1;
                numberFormat.setCurrency(Currency.getInstance(type2));
                edt2.setText(numberFormat.format(result));
            }
