毕竟我已经设法为NDK“准备”我的eclipse(至少我认为是这样),它不再争论c代码,但现在我在任何时候执行任何本机代码时都会得到“没有找到本机Lcom的实现”。 . 它也发生在 NDK 的样本上..
我的.java
...
private native float pi();
static
{
System.loadLibrary("shit");
}
...
System.out.println(pi());
...
我的.cpp
#include <jni.h>
jfloat Java_com_example_shit_MainActivity_pi(JNIEnv * env, jobject obj) {
return 3.1415;
}
我的.mk
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := shit
LOCAL_SRC_FILES := shit.cpp
include $(BUILD_SHARED_LIBRARY)

为什么我会得到那个该死的“没有找到本机的实现”???
