JNI和Android ... UnsatisfiedLinkError

Man ...这个bug让我失望。JNI和Android ... UnsatisfiedLinkError

的logcat：

加载库，并声明它：

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功能：

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) { 
    /* ... */ 
}

我跑

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

我不能得到任何工作。任何建议，或经验与这个问题？ logcat中的调用行是我只是试图调用函数，顺便说一句。感谢您......请我的英雄:(

，我不知道我该怎么做它：C++中，JNI

使用在本机端此方案来声明数组工作，不幸的是，这个函数只是让这个Activity退出错误消息...所以我们在这里发现另一个bug：/ – 2011-01-30 06:55:36

阵列并没有转化为数组类型的指针在C /再次
双[]使用jdoubleArray
短期[]使用jshortArray

稍后发现。谢谢。 – 2011-01-31 20:48:11

贵库使用其他C/C++库，并使用系统路径是那些可达？在Java中
