Android - Debugging prebuilt native libraries with lldb

Question

How can I get lldb to see a prebuilt native library's symbols when using the latest Android Studio tools?

I'm working on an Android app using Android Studio 2.2.2. My app has a native component and also depends on a prebuilt native library that my native component links to. When I break into some native code with the debugger, the debugger has symbols for my native code but not for the prebuilt library, which I built with symbols. The documentation that I've found on debugging prebuilt native libraries (https://developer.android.com/ndk/guides/prebuilts.html#dp) appears to be outdated, as it refers to Android.mk and ndk-gdb, as opposed to build.gradle, CMakeLists.txt, and lldb, which are what I'm using.

Here's a bit more info for anyone who's familiar with lldb (which is not to say that I am familiar with it). I think it reflects the fact that the debugger is looking at the non-symbol-stripped version of my native code, in libnative-lib.so, which is stored on my machine, but is looking at the symbol-stripped version of the prebuilt library, libaws-cpp-sdk-vitalservices.so, which is stored on the android device:

How large is your executable ?

It seems that the lldb client for Android Studio is a 32b application so it cannot handle large so files!

It seems it will be fixed soon !
