[原创]cmake和Android.mk两种编译c/c++双编译的样板代码

Android.mk

在gradle 安卓项目的build.gradle文件下的android{} 内插入

externalNativeBuild {ndkBuild {path 'src/main/jni/Android.mk'}

在gradle 安卓项目的build.gradle文件下的android.defaultConfig{} 内插入

android{defaultConfig {ndkBuild {abiFilters "armeabi-v7a",'arm64-v8a','x86_64'abiFilters "armeabi-v7a",'arm64-v8a'}}}

Cmake

在gradle 安卓项目的build.gradle文件下的android{} 内插入

externalNativeBuild {cmake {path "CMakeLists.txt"}

在gradle 安卓项目的build.gradle文件下的android.defaultConfig{} 内插入

android{defaultConfig {cmake {
//            arguments '-DBUILD_TESTING=OFF', '-DANDROID_TOOLCHAIN=gcc'arguments "-DANDROID_STL=c++_shared", "-DSHARED=false", "-DDEBUG=OFF", "-DFUCKDEBUG=ON", "-Wno-error=format-security"
//打开hook zz日志。
//解决roid.injected.build.abi'gradle标志设置的ABIs [armeabi-v7a，armeabi]包含的'ARMEABI'不是此项目的目标cppFlags "-fexceptions", "-fpermissive", "-fno-exceptions"}}
}

双支持

在项目build.gradle 下定义

ext{USE_CMAKE=false
}

在android项目build.gradle定义判断即可

gradle中 宏定义的读取

gradle.中

cmake {arguments "-DFUCKDEBUG=ON", "-Wno-error=format-security"
}

cmakeList.txt

if (FUCKDEBUG)message("---------open log FUCKDEBUG---------------")add_definitions(-DFUCKDEBUG)

android.mk

# -DFUCKDEBUG open log

c代码

#if defined(FUCKDEBUG)#pragma message("-----MY LOG_ ON----")
#endif
