Related Java 8 DecimalFormatSymbols Questions & Answers:

How can I format a number to the fixed locale? 
1:	 public static String addCommas(int num) {
2:	    DecimalFormat df = new DecimalFormat();
3:	    DecimalFormatSymbols dfs = new DecimalFormatSymbols();
4:	    dfs.setGroupingSeparator(',');
5:	    df.setDecimalFormatSymbols(dfs);
-
1:	 public static String addCommas(int num) {
2:	    DecimalFormat df = new DecimalFormat();
3:	    DecimalFormatSymbols dfs = new DecimalFormatSymbols();
4:	    dfs.setGroupingSeparator(',');
5:	    df.setDecimalFormatSymbols(dfs);

Yes, there is a "trick" in Java:

public static String addCommas(int num) {
    DecimalFormat df = new DecimalFormat();
    DecimalFormatSymbols dfs = new DecimalFormatSymbols();
    dfs.setGroupingSeparator(',');
    df.setDecimalFormatSymbols(dfs);
    return df.format(num);
}

System.out.println(addCommas(123456789));

EDIT: In case you want your output to be independent from locale you can use the method below. It starts from the end so there is no need to reverse the string and should be quite efficient:

public static String addCommas(int num) {
    StringBuilder s = new StringBuilder(Integer.toString(num));
    for(int i = s.length() - 3; i > 0; i -= 3) {
        s.insert(i, ',');
    }
    return s.toString();
}

Decimal point or decimal comma in Android 
1:	 NumberFormat nf = NumberFormat.getInstance();
2:	if(nf instanceof DecimalFormat) {
3:	    DecimalFormatSymbols sym = nf.getDecimalFormatSymbols();
4:	    char decSeparator = sym.getDecimalSeparator();
5:	}

I believe I have a way. I've never USED this, mind you, but it should certainly get you close, if not there:

NumberFormat nf = NumberFormat.getInstance();
if (nf instanceof DecimalFormat) {
    DecimalFormatSymbols sym = ((DecimalFormat) nf).getDecimalFormatSymbols();
    char decSeparator = sym.getDecimalSeparator();
}

Docs:

NumberFormat, DecimalFormat, DecimalFormatSymbols

According to the DecimalFormat docs, apparently calling NumberFormat.getInstance() is safe, but may return a subclass other than DecimalFormat (the other option I see is ChoiceFormat). I believe for the majority of instances it should be a DecimalFormat, and then you can compare decSeparator against a , and . to see which format it is using.

need to format currency for TextView 
1:	 DecimalFormatSymbols symbols = new DecimalFormatSymbols();
2:	symbols.setGroupingSeparator('\'');
3:	symbols.setDecimalSeparator(',');
-
1:	 DecimalFormatSymbols symbols = new DecimalFormatSymbols();
2:	symbols.setGroupingSeparator('\'');
3:	symbols.setDecimalSeparator(',');

The format you need is € #,###.00, , means you use a grouping separator.

Then, you need a DecimalFormatSymbols to specify the grouping symbol and the decimal symbol:

DecimalFormatSymbols symbols = new DecimalFormatSymbols();
symbols.setGroupingSeparator('\'');
symbols.setDecimalSeparator(',');

DecimalFormat decimalFormat = new DecimalFormat("€ #,###.00", symbols);
String prezzo = decimalFormat.format(number);

Result € 1'515,28

NumberFormatException on European Versions of Android? 
1:	 DecimalFormatSymbols symbols = DecimalFormatSymbols.getInstance(Locale.US);
2:	DecimalFormat format = new DecimalFormat("#.00", symbols);

Is it really possible that DecimalFormat is producing a comma version of the decimal on European phones?

Yes, absolutely. That's what it's meant to do, after all:

Creates a DecimalFormat using the given pattern and the symbols for the default locale. This is a convenient way to obtain a DecimalFormat when internationalization is not the main concern.

To obtain standard formats for a given locale, use the factory methods on NumberFormat such as getNumberInstance. These factories will return the most appropriate sub-class of NumberFormat for a given locale.

Note that this isn't a matter of a "European version of Android" - it's just a matter of using Android in a context where the default locale uses , as the decimal separator.

If you want to use the symbols for a particular locale, but using a specific pattern, you could use:

DecimalFormatSymbols symbols = DecimalFormatSymbols.getInstance(Locale.US);
DecimalFormat format = new DecimalFormat("#.00", symbols);

Having said that, it's not at all clear what you're trying to do in the first place - why would you format and then parse a number? You should almost always avoid string conversions when you don't really need them. Why not just convert it directly? (We don't know what totalNumberOfCredits is, which doesn't help.)
