Question

我创建了一个支持C ++的Android Studio项目，其中包含一个库模块。名为native-lib.cpp的C ++文件自动添加到我的项目中。当我现在构建项目时，* .so文件的输出名称为libnative-lib.so。

如果我将native-lib.cpp重命名为其他任何内容（使用重构/重命名功能），C ++文件将从我的项目中消失，直到我更改名称为止。

那么如何重命名我的本机库，或者设置输出文件的名称？

我很高兴你能搞清楚。我会在这里发布答案以供参考。

CMakeLists.txt＆lt;＆lt; =应该在您的应用模块的根目录（my_project/app/CMakeLists.txt）中

# https://developer.android.com/studio/projects/add-native-code.html#create-cmake-script


# Minimum version of CMake
cmake_minimum_required(VERSION 3.4.1)


# adding CEC library
# add_library structure:    add_library(lib_name  lib_type_STATIC_or_SHARED  source_file_path)
add_library(my_lib_name SHARED src/main/jni/my_cpp_file.cpp)


# include_directories is to provide the path to you native lib code
# include_directories structure:    include_directories(native_lib_folder_path)
include_directories(src/main/jni/)


# adding Android log library
# find_library is used to find NDK API libraries (built in NDK libs)
# find_library structure:   find_library(name_you_want_to_call_the_lib  lib_name_in_ndk_api)
find_library(log-lib log)


# linking log lib to our native lib
# once you find the library, you have to link that library with your native library
# target_link_libraries structure:  target_link_libraries(you_native_lib  lib_found_using_find_library)
target_link_libraries(my_lib_name ${log-lib})

然后在build.gradle中，执行以下操作

externalNativeBuild {
    cmake {
        path 'CMakeLists.txt'
    }
}

然后，执行完全清理，使用“生成”菜单中提供的选项刷新C ++项目。

和@bitwise一样，如果必须，删除build和.externalNativeBuild文件夹的内容并重建项目。

Android Studio重命名本机库
