Android 用NDK构建音频处理小端SDK

我正在尝试使用

ndk build

在Android应用程序中使用本机代码进行音频处理（我还没有JNI）

当我在jni目录中执行ndk构建时，我得到（$USER\u PATH是我计算机上目录的路径）：

我看到这是因为预构建的静态库指向丢失的文件

我怎样才能解决这个问题

目录结构：

有.mk文件：

Android.mk Application.mk le_Audiio.mk le_utilityio.mk

---

尝试Google针对音频应用程序的新解决方案。

我检查了成功从application.mk构建中删除NDK_工具链版本：=clang和APP_STL:=c++\u static。看起来你在混合共享库和静态库所需的逻辑。您实际希望在应用程序中使用什么？当前的逻辑指定BuudLySydDLBooLover，但请求C++ STL的静态版本。
