JNI and Android... UnsatisfiedLinkError

Man... this bug has got me down.

Logcat:

Loading the Library and declaring it:

    public native void RicianDenoise(int w, int h, int p, 
        short [] s_noised_slice, double [] d_noised_slice, 
        short [] s_denoised_slice, double [] d_denoised_slice);

    static {
        System.loadLibrary("denoise");
    }

C Function:

void 
Java_com_example_viewer_Viewer_RicianDenoise (JNIEnv *env, jclass cls, jint M, 
                                              jint N, jint P, jshort * s_noised_slice,
                                              jdouble * d_noised_slice, 
                                              jshort * s_denoised_slice, 
                                              jdouble * d_denoised_slice) {
    /* ... */
}

I ran

ndk-build -B -C [project]/jni

and I can't get anything to work. Any suggestions, or experience with this issue? The invocation line in the logcat is me just trying to call the function, btw. Thank you... please be my hero :(

Arrays in java do not translate into array type pointers in C/C++, in JNI

Use this scheme on the native side to declare your arrays:
for double[] use jdoubleArray
for short[] use jshortArray

Does your library use other C/C++ libraries and are those reachable using the system path?
