先上代码
cmake_minimum_required(VERSION 3.4.1) #添加头文件的路径(相对于本文件路径) include_directories(include)//引入include文件夹 string(REGEX REPLACE "(.+)\\src/main/cpp.*" "\\1" PROJECT_INIT_PATH ${PROJECT_SOURCE_DIR})//用cmake目录生成新路径即项目根路径(项目目录/app ) set(FF ${PROJECT_INIT_PATH}/libs/${ANDROID_ABI})//赋值变量到FF add_library(avcodec SHARED IMPORTED)//添加avcodeclibrary set_target_properties(avcodec PROPERTIES IMPORTED_LOCATION ${FF}/libavcodec.so)如果上述路径配置错误的话会出现
Execution failed for task ':app:externalNativeBuildDebug'.
