NumberFormatException in European versions of Android?

I have an application that runs the following two lines of code at startup:

DecimalFormat decim = new DecimalFormat("#.00");
return Double.parseDouble(decim.format(totalNumberOfCredits));

When I run the application on my American phone, the value decim.format(totalNumberOfCredits)is equal .00.

However, in my Google Play Developer Console, I have a dozen crashes, all of which look like this:

Caused by: java.lang.NumberFormatException: Invalid double: ",00"
at java.lang.StringToReal.invalidReal(StringToReal.java:63)
at java.lang.StringToReal.parseDouble(StringToReal.java:269)
at java.lang.Double.parseDouble(Double.java:295)

Is it possible that DecimalFormat produces a comma version of the decimal number on European phones?
