我们可以从一个android ndk应用程序使用.so文件到另一个android ndk应用程序吗？

Question

My question is that have created one android ndk project which is having its respective .so file.I want to know that can we use same .so file in another android ndk application without copying as it is from one project to another? If yes how can we implement that?

Answer 1

是的，如果您在相同程序包的相同类中定义了相同的“本地”调用，则可以。

Answer 2

Native libraries are installed in lib directory for an application, which is readable for anyone. Therefore, appB can use

System.Load("/data/data/com.appA/lib/libnativeA.so")

But the guess of the full path to other package's libraries is not based on documented interfaces, and there is no guarantee this will work in future versions.
