There are a couple methods that have been changed to take float instead of double here: http://developer.android.com/intl/fr/reference/android/util/FloatMath.html
I've actually been doing my trig and other complex calculations using fixed point integers myself. You can find a lot of utilities/libraries for that sort of thing that were originally written for J2ME, but that work on Android.
