NDK 编译环境配置

NDK 编译环境配置遇到问题和解决方案

环境
AndroidStudio 3.0.1
Window10

• No toolchains found in the NDK toolchains folder for ABI with prefix

No toolchains found in the NDK toolchains folder for ABI with prefix: mips64el-linux-android

类似这种问题，感谢 https://www.jianshu.com/p/fd3d49c7f1f8

AndroidStudio 下载安装下来的NDK，缺少 mips64el-linux-android-4.9 和 mipsel-linux-android-4.9 工具，所以，通过 https://developer.android.google.cn/ndk/downloads/?hl=zh-cn
下载安装包，将缺少的工具拷贝进去重新编译即可

• 编译错误

在解决这个的时候，也是去网上搜索，感谢

这个回答，但是按照这样修改还是报类似的错误，
仔细查看报的错误信息：

打开CMakeLists.txt 这个文件193行：

问题很明确了，不支持 armeabi 了，所以像之前问题回答的同学那样，修改build.gradle

多去了 armeabi，就可以编译通过了。
