DecimalFormatSymbols 异常

Question

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

我已将我的应用程序翻译成阿拉伯语。在我的设备上一切正常，但在 Google Analytics 中，我从阿拉伯用户那里收到了很多这样的错误。当我将我的设备设置为阿拉伯语时，在我的设备上也一切正常。

有什么想法吗？

编辑：

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)
    { }

问题仅在 android API 21.

之后的 rtl 语言环境（阿拉伯语、希伯来语等）中发生

该问题将在下一个版本中修复。
