DecimalFormatSymbols exception

Question

UnsupportedOperationException (@DecimalFormatSymbols:getMinusSign:300) {main}

I've translated my app in arabic. On my devices all is ok, but in Google Analytics I received a lot of this error from arabic users. On my device all works also when I set my devices into arabic.

Any ideas?

EDIT:

DecimalFormatSymbols nf = new DecimalFormatSymbols();
    try
    {
        nf.setDecimalSeparator(sharedPref.getString("pref_currency_decimal_separator", ".").charAt(0));
        nf.setGroupingSeparator(sharedPref.getString("pref_currency_thousands_separator", ",").charAt(0)); 

        formatter_currency.setDecimalFormatSymbols(nf);
        final int digits = sharedPref.getInt("pref_currency_decimal_places", 2);
        formatter_currency.setMaximumFractionDigits(digits);    
        formatter_currency.setMinimumFractionDigits(digits);
    }
    catch(IllegalArgumentException e)
    {
        currency = "$";

        nf.setDecimalSeparator('.');
        nf.setGroupingSeparator(',');

        formatter_currency.setDecimalFormatSymbols(nf);
        formatter_currency.setMaximumFractionDigits(2);
        formatter_currency.setMinimumFractionDigits(2);
    } 
    catch(UnsupportedOperationException e)
    { }

Answer 1

The problem happen only in rtl locales (arabic, hebrew, etc.) after android API 21.

The problem will be fixed in the next releases.
