Java code will take advantage of it automatically. Native code must be recompiled. The NDK currently only supports soft float, but that will change in an upcoming release. Native code is either built for hardware float or compiler-supported software emulation. Attempting to use FP instructions on a device without an FPU will earn you a SIGILL. The performance of kernel exception handling is too awful to consider. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
