我正在处理 Android使用 Java 的项目作为 C++ 上的包装器的类图书馆。 C++库是公司内部库，我们可以访问它的源代码，但是在Android项目中它只是动态链接的，所以只能以头文件(.h)和共享对象(.so)的形式使用。可以访问库源代码，是否可以向 Android Studio 指定源代码的路径，以便我可以使用调试器进入库？

调试器工作，我可以进入 Java_clory_engine_sdk_CloryNative_nativeInit函数，不过我还想进一步调试Clory::Engine对应的库正如我所提到的，它是一个我们可以访问源代码的内部库。



例如，Clory::Engine::instance是库的一部分，我想向 Android Studio 指定 CloryEngine.cpp 的位置文件，这样我就可以进入 Clory::Engine::instance用调试器，从而调试这个静态成员函数。

我正在使用 Android Studio 3.1.4。

这可能吗？

编辑:
clory-sdk.gradle文件指定 CMakeLists.txt配置 C++ 层的文件。

externalNativeBuild {
    cmake {
        path "CMakeLists.txt"
    }
}

dependencies {
...
    compile project(':clory-sdk-core')
    compile project(':clory-sdk')
...
}

最佳答案

调试信息记录源文件在构建时的位置。

(lldb) image lookup -vrn Clory::Engine::instance

"/BuildDirectory/Sources/Clory/CloryEngine.cpp"

"Users/me/Sources/Clory"

(lldb) settings set target.source-map /BuildDirectory/Sources/Clory Users/me/Sources/Clory
