Unless you have created the Application.mk or defined your application as debuggable inside the AndroidManifest.xml you don't have to do anything because by default the application's modules are compiled in release mode by the ndk-build script.

Otherwise, you can use the APP_OPTIM directive inside the Application.mk file:

APP_OPTIM := debug

APP_PLATFORM := android-14

APP_STL := gnustl_static

APP_ABI := armeabi armeabi-v7a

From android-ndk-r8d/docs/APPLICATION-MK.html file:

APP_OPTIM

This optional variable can be defined to either 'release' or

'debug'. This is used to alter the optimization level when

building your application's modules.

A 'release' mode is the default, and will generate highly

optimized binaries. The 'debug' mode will generate un-optimized

binaries which are much easier to debug.

Note that if your application is debuggable (i.e. if your manifest

sets the android:debuggable attribute to "true" in its

tag), the default will be 'debug' instead of 'release'. This can

be overridden by setting APP_OPTIM to 'release'.

Note that it is possible to debug both 'release' and 'debug'

binaries, but the 'release' builds tend to provide less information

during debugging sessions: some variables are optimized out and

can't be inspected, code re-ordering can make stepping through

the code difficult, stack traces may not be reliable, etc...
