Qt for android, how to debug own shared library.

[qedufun]

I use NDK to build a library with -g debug symbols. I use Qt widget application to load the library.
But I cannot debug into the library code.

BTW, I use the same machine, and OS is unbuntu 13.04, Qt for Android 5.3 beta, Java 1.6?

Anything am I missing? thank you very much!

Does anyone can help me?
Or give me some tips on how to debug NDK so, load symbols or map debug source code?
