在 Android NDK 项目中使用我自己的预构建共享库 [英] Using my own prebuilt shared library in an Android NDK project

问题描述

我发现这篇文章几乎是我需要的:

I came across this post that is almost what I need:

如何使用Android编译静态库NDK?

基本上，我的项目中有某些部分从未更新过，因此我试图避免每次更新 Android.mk 文件以添加内容时都构建它们.

Basically, there are certain parts in my project that are never updated, so I am trying to avoid having them built every single time I update the Android.mk file to add something.

上面的答案显示了如何将一些代码构建到单独的静态库中，但是当我尝试在单独的 Android.mk 文件中预构建上述代码时，它不会自行构建.这似乎有点多余......如果我必须同时构建它们，那么无论如何制作单独的静态库有什么意义?

The above answer shows how to get some of the code built into a separate static lib, but when I try to pre-build the above code in a separate Android.mk file, It won't build by itself. This seems a little redundant... If I have to build them both at the same time, then what's the point of making a separate static lib anyways?

如果我将单独项目中的 Android.mk 更改为读取:

And if I change Android.mk in the separate project to read:

包含 $(BUILD_SHARED_LIBRARY)

include $(BUILD_SHARED_LIBRARY)

并像这样将其包含在主项目中:

and include it like this in the main project:

LOCAL_SHARED_LIBRARIES := libMyaccessories.so

LOCAL_SHARED_LIBRARIES := libMyaccessories.so

然后我得到了对(函数名)的未解析引用，可能是因为它找不到共享库(在调用路径中)

then I get unresolved reference to(function name), probably because it can't find the shared lib(which is in the calling path)

谁能帮我解决这个问题?

Can anyone help me out with this?

推荐答案

在Android.mk的文档中，查看PREBUILT_SHARED_LIBRARY脚本描述.将 .so 文件放在 lib(不是 libs)目录中，并在它旁边写一个 Android.mk 文件，如下所示:

In the documentation of Android.mk, check the PREBUILT_SHARED_LIBRARY script description. Put the .so file in lib (not libs) directory and write an Android.mk file next to it that looks something like:

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := Myaccessories
LOCAL_SRC_FILES := libMyaccessories.so
LOCAL_C_INCLUDES := $(LOCAL_PATH)/../jni/include

include $(PREBUILT_SHARED_LIBRARY)
