Android Studio Cmake配置项

Cmake的配置

Android Studio 2.2以上支持了Cmake的配置JNI的相关参数，简化了通过Android.mk配置。并很好的继承了C++的编辑方式。以下是对应的引入第三方so和第三方.cpp文件的路径脚本编写。对应于：CMakeLists.txt

#定义变量ProjectRoot为工程根目录，用相对路径没通过编译，可能是路径写错，以后再试#本次使用绝对路径作为参数set(Project D:/GitHub/EchoCancellation)#动态方式加载 speex是libxxxx.so的xxxx部分add_library(speex SHARED IMPORTED)#设置要连接的so的相对路径，${ANDROID_ABI}表示so文件的ABI类型的路径,这一步引入了动态加入编译的soset_target_properties(speex PROPERTIES IMPORTED_LOCATION                      ${Project}/app/src/main/jni/${ANDROID_ABI}/libspeex.so)#配置加载native依赖#include_directories( ${Project}/app/src/main/jni/include )#将native-lib加入到编译源中add_library( # Sets the name of the library.             native-lib             SHARED             src/main/cpp/native-lib.cpp )find_library( # Sets the name of the path variable.              log-lib              log )#这里多出了引用的speextarget_link_libraries( # Specifies the target library.                       native-lib                       speex                       # Links the target library to the log library                       # included in the NDK.                       ${log-lib} )

build.gradle的配置

此处配置主要是我们写的JNI层的代码，可以通过编译为SO文件，被我们的项目引用。生成的so,在你对应项目的build中进行查找。
