手动(Aapt)将本机库.so添加到APK [英] Manually (aapt) add native library .so to apk

问题描述

出于多种原因，我正在手动构建项目(或多或少地遵循以下步骤 http://geosoft.no/development/android.html )，而没有使用ant.

For multiple reasons I'm building my project manually (more or less following these steps http://geosoft.no/development/android.html), whithout using ant.

我的项目使用NDK并构建了一个 .so 库.

My projects uses the NDK and builds a .so library.

• 使用Eclipse:

使用Eclipse构建项目时，一切正常:将 libMyNativeLib.so 拖放到 libs/armeabi 目录中，并调用 loadLibrary(MyNativeLib)正常工作:我可以从Java代码中调用本地方法.

When I use Eclipse to build my project, everything works: I drag&drop libMyNativeLib.so in the libs/armeabi directory and when I call loadLibrary(MyNativeLib) it works fine: I can call native method from my Java code.

• 手动:

现在，我想手动构建 .apk .除了从本地lib加载，一切都可以正常工作.使用 aapt add ，我在我的apk中添加了 lib/armeabi/libMyNativeLib.so (我看到Eclipse生成的apk在 lib中包含此.so/armeabi ，因此我在apk中使用了相同的路径).调用 loadLibrary(MyNativeLib)时，出现以下异常

Now I want to build manually my .apk. Everything works except from the native lib loading. Using aapt add, I have added in my apk : lib/armeabi/libMyNativeLib.so (I saw that the apk generated by Eclipse contains this .so in lib/armeabi so I used the same path in the apk). When calling loadLibrary(MyNativeLib), I got the following exception

java.lang.UnsatisfiedLinkError: Couldn't load MyNativeLib from loader dalvik.system.PathClassLoader[DexPathList...

那是为什么?

我是否应该在 dx --dex 步骤中针对本机代码( .so lib)执行某些操作?我不这样认为，但我可能错了吗?(我只将 dx --dex 与我的 .jar 库一起使用，这是我想的逻辑).

Should I do something in the dx --dex step regarding the native code (.so lib) ? I don't think so but I'm maybe wrong ? (I'm only using dx --dex with my .jar libs which is logic I guess).

你有什么主意吗?

谢谢

推荐答案

感谢apktool( http://ibotpeaches.github.io/Apktool/)我发现了问题所在.

Thanks to apktool (http://ibotpeaches.github.io/Apktool/) I found out what was wrong.

生成最终 .apk 包的makefile出错.实际上， aapt add 命令在路径中包含 \ 而不是/.在Windows上生成时，我所有的路径都使用 \ 作为分隔符.这就是为什么我将 \ 用于 aapt add 的原因.但是，由于在Android(Unix)上 .apk 的安装过程中使用了此路径，因此我应该使用/分隔符.

The makefile that generates the final .apk bundle had an error. Indeed the aapt add command contained \ in the path instead of /. As I'm generating on Windows, all my paths use \ as a separator. That's why I used \ for aapt add. However as this path is used during the installation of the .apk on Android (Unix), then I should have used / separator.
