我用的是Android studio2.3.3

必须把你的包名与类名与他的接口一致，比如接口是 Java_com_example_sdembeddeddemo_MainActivity_UnloadSD( JNIEnv* env, jobject thiz)
那么你的包名就得是com.example.sdembeddeddemo,类名就得是MainActivity；因为接口再生成的时候会自动带上Java、包名、类名；

不要沉啊，大神们帮帮忙，谢谢了

自己再顶个！！！跪求大神啊，网上搜了很多天了都没解决。

报的错误不是说的很明白了吗，没有找到你实现的方法

自己再顶下，求大神帮忙啊

楼主解决了这个问题了吗，遇到相同的问题，请指教

有没有一种可能，你的activity 没有加载你的c的lib

static {
        System.loadLibrary("你的包名");
    }

问题出在C文件中,在extern "C"后面加上大括号{},然后将所有的方法被{}包裹,解决!
