android_ndk_perf: Symbols not appearing in reports.

[mhess-connectify]

I'm trying to profile my NDK code, but symbols don't show up in the results. I've followed the steps to enable debuggable builds, and i can see function names using nm on the .a file in my libs folder. But this is what i see in the HTML report:

You need to make sure your build is debuggable and contains symbols, e.g if
you're building with ndk-build:

https://developer.android.com/ndk/guides/ndk-build.html#dvr

If you're using fplutil to indirectly build using ant + ndk-build:

http://google.github.io/fplutil/android_ndk_perf.html#android_ndk_perf_building

If you're debugging on an armeabi-v7a architecture device you need to make
sure you've added the -mapcs-frame flag to gcc / clang's command line
(again see
http://google.github.io/fplutil/android_ndk_perf.html#android_ndk_perf_building
)

If you've been incrementally building it may be worth cleaning and
rebuilding with the debugging options enabled to verify you're building
with symbols.

Cheers,
Stewart
