Answer 1

Quite painlessly, FFTW can be built for Android with its official CMake script in http://fftw.org/fftw-3.3.8.tar.gz:

externalNativeBuild {
    cmake {
        arguments "-DANDROID_ARM_NEON=TRUE"
        arguments "-DCMAKE_BUILD_TYPE=Release"
        arguments "-DBUILD_SHARED_LIBS=OFF"
        arguments "-DBUILD_TESTS=OFF"
        arguments "-DDISABLE_FORTRAN=ON"
        arguments "-DENABLE_FLOAT=ON"
        targets "fftw3f"
    }
}
