Android NDK 未找到实现

Question

W/dalvikvm(3937): No implementation found for native Lcom/video/v2/camera/ExternalCamera;.converttobmp (Landroid/graphics/Bitmap;)V

使用公共(public)类ExternalCamera加载库

static {
            try {
                System.loadLibrary("ExternalFullHd");
            } catch (UnsatisfiedLinkError e) {
                e.getMessage();
            }
    }   
public native void converttobmp(Bitmap bitmap);

在ExternalFullHd.c和ExternalFullHd.h中我有

void Java_com_video_v2_camera_ExternalCamera_stopCamera(JNIEnv* env,jobject thiz);
void Java_com_video_v2_camera_ExternalCamera_converttobmp ( JNIEnv* env,jobject thiz,jobject bitmap);

&

void 
Java_com_video_v2_camera_ExternalCamera_converttobmp( JNIEnv* env,jobject thiz,jobject bitmap){
//code

}

正如我的评论中所述，不要忘记将您的 C/C++ 函数声明为 extern "C" 和 JNIEXPORT。
