Android : android decimalformat for arabic, symbol is on right side of number

I'm trying to support RTL to left languages, and I'm testing with Arabic (which I know nothing about).

Is the negative/positive symbol supposed to be on the right or left of the number? I think it's supposed to be on the left, but when I use Android's DecimalFormat to put the number in the locale the device is set to, the symbol appears on the right..

Has anyone encountered this, know how to work around it? Best I can think is to print it with parentheses if it's negative, that should get around this but isnt ideal.
