How does APP_OPTIM manifest in code?

Question

In Application.mk you can set:

APP_OPTIM := release
APP_OPTIM := debug

How can I test for release/debug build in C++?

I\'m assuming the

Answer 1

In android-ndk-r8b/build/core/add-application.mk we read:

ifeq ($(APP_OPTIM),debug)
  APP_CFLAGS := -O0 -g $(APP_CFLAGS)
else
  APP_CFLAGS := -O2 -DNDEBUG -g $(APP_CFLAGS)
endif

So, to answer your question: in NDK r8b (the latest for today) you can check

#ifdef NDEBUG
// this is "release"
#else
// this is "debug"
#endif

But you can add any other compilation flags through your Android.mk or Application.mk depending on $(APP_OPTIM), if you want.
