继上次Android Studio下编译LatinIME so库NDK版，这次简单记录一下使用CMake编译的so库
编译环境
- Android Studio 3.1.3
- gradle 4.4-all
- cmake (sdk目录下)
- ndk-bundle (sdk目录下)
- 源码 Android 8.1
(1) packages目录的LatinIME
(2) 支持包framework的opt目录下的 inputmethodcommon
确保cmake与ndk-bundle已经下载了并配置好
cmake ndk-bundle.png
ndk-bundle路径.png
导入源码，如图
cmake导入LatinIME源码.png
在源码的native目录下新建 CMakeList.txt文件，加入cmake的配置
cmake_minimum_required(VERSION 3.4.1)
# 二进制码剥除
set(CMAKE_C_FLAGS_RELEASE "${CMAKE_C_FLAGS_RELEASE} -s")
set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -s")

打开Android Studio并导入工程，同步完成之后点击构建
点击构建.png
构建完成后，在目录 build\intermediates\cmake\release\obj下即可找到so库
so库.png
或者直接从生成的apk中用压缩包打开，将lib目录拖出来就是so库了。
源码点这里LatinIME/cmake
