My project has a NDK layer that is the glue to a C++ library. My JNI code compiles against the header files for that library and I load the library at runtime (System.loadLibrary). The library itself is provided to me as a single .so file.
Android Studio allows me to navigate into the JNI code. When I try to navigate into the library, though (Go to Declaration), I am, unsurprisingly, sent to the .h file.
Similarly, when debugging, as soon as I descend into the library, I can no longer see the corresponding source.
I have access to the sources for the library. Is there any way that I can attach those sources so that
Navigation works: Go to Declaration shows two choices: the .h definition and the .cc definition
Debugging shows the corresponding source: When I'm debugging, I can see the source, add breakpoints in the source, etc.

I recently got into the same situation as the standalone ndk toolchain produces a lib that crashes on unwind. The only solution that worked for me on windows was to copy the cpp sources and headers to a directory (in my case src/main/cpp) as there's no symlink on windows but if you're on linux [or bsd ;)], a directory with a symlink would do I think. You also have to include that directory in CMakeLists [for me it is: include_directories(src/main/cpp)] and list those cpp files in your JNI library section. Here's a screenshot of what I did in cmake(along with my notes for myself about the steps):

Isn't that going to make CMake try to build it???

Yes, this way CMake will build the native c++ code.

Yeah... that won't work. That will just make the build fail. While I have source for the library on which I depend, I have neither source nor artifacts for its dependencies.

Yeah...thanks, but that is not a solution. While I have the source for the library on which I depend, I don't have the artifacts necessary to build it.

Yepp, that's tough. In my case, all my dependencies are open source so I could cross compile them for arm.
