Android Studio抱怨缺少JNI类[重复]

Question

为什么我的 Android Studio 没有找到相关的 JNI 类？

我在 AsyncTask 中有一个名为 opensslSign 的类，它与 jni .so 文件 libcryptowrapper.so 相关。构建工作正常，但 Android Studio 抱怨：“无法解析相应的 JNI 函数”。我已将我的 .so 文件移动到多个文件夹中，只是为了查看 Android 是否找到它，但没有运气。

This is a screenshot Android Studio 能够在.so 文件和jni 类目录中找到JNI 类（包含Android.mk）
