Well, it depends on how many different frequency bins he wants and how complicated a windowing function. If he wants lots of bins and a fancy window, he will wish he had direct access to the DSP on the phone as well as raw audio.
Otherwise, he can get a lot of mileage out of an FFT algorithm even in plain Java. Processors are so much faster these days, even on a phone.
