Android Renderscript rotateLeft

How do I implement this Java function:

    public static int rotateLeft(int i, int distance) {
        // Shift distances are mod 32 (JLS3 15.19), so we needn't mask -distance
        return (i << distance) | (i >>> -distance);
    }

In Renderscript?

It's the same as C, so something like

static int rotateLeft(int i, int distance) {
  return (i << (distance % 32)) | ((unsigned int)i >> (32 - (distance % 32)));
}
