Android NDK 设置编译模式debug和release

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 <application>

    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...
