Question

我试图在发布模式下构建我的android项目。为了在发布模式下构建我的项目，是否需要设置任何优化标志？

Answer 1

除非您已经在AndroidManifest.xml中创建了Application.mk或将您的应用程序定义为debuggable，否则您无需执行任何操作，因为默认情况下应用程序的模块在 release 中编译模式由ndk-build脚本。

否则，您可以在Application.mk文件中使用APP_OPTIM指令：

APP_OPTIM := debug
APP_PLATFORM := android-14
APP_STL := gnustl_static
APP_ABI := armeabi armeabi-v7a

来自android-ndk-r8d / docs / APPLICATION-MK.html文件：

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...
