BigDecimal gives NumberFormatException in Android 4.0.3 with localization

Question

I am doing localization in my app with Persian(locale-"fa") and Pashto(locale-"ps") languages.. When i am trying to convert double value in BigDecimal using Decimal Foramt then it gives NumberFormatException in 4.0.3 with Persian language.

Following is my code to get two decimal places:

public static String roundTwoDecimals(double d) {

    System.out.println("===================Amount in double "+d);
    DecimalFormat twoDForm = new DecimalFormat("#############.##");
    String format=twoDForm.format(d);
    System.out.println("===================Amount after formatting "+format);
    return new BigDecimal(twoDForm.format(d)).toPlainString();
}

LogCat:

03-26 15:19:29.714: I/System.out(1475): ===================Amount in double 166308.37
03-26 15:19:29.723: I/System.out(1475): ===================Amount after formatting ۱۶۶۳۰۸٫۳۷

Actual amount is 166308.37 and when i change language to persian("fa") and format it, it gives amount like ۱۶۶۳۰۸٫۳۷ in 4.0.3 . So this string can not be converted to BigDecimal and gives NumberFormatException.

And strange problem is that except 4.0.3, it works perfectly fine.

Try this code..

public static String roundTwoDecimals(double d) {

    NumberFormat nf=NumberFormat.getCurrencyInstance(Locale.ENGLISH);
    DecimalFormat df = (DecimalFormat)nf;
    df.applyPattern("#############.##");
    String output = df.format(d);

    return new BigDecimal(output).toPlainString();
}
