Android NDK编译错误解决

0x01 问题描述

现象： 将ndk版本升级到 17.0.4754217编译报错

* What went wrong:
Execution failed for task ':app+stub:transformNativeLibsWithStripDebugSymbolForRelease'.
> A problem occurred starting process 'command '/Users/Ivonhoe/Library/Android/sdk/ndk-bundle/toolchains/mips64el-linux-android-4.9/prebuilt/darwin-x86_64/bin/mips64el-linux-android-strip''

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

原因：

升级android ndk版本到17时未同时升级gradle编译工具到3.0.0以上，低版本的编译工具会执行mips64的脚本。而mips64的脚本在ndk17上已经被删除了！

This mipsel-linux-android-4.9 directory exists to make the NDK compatible with the Android
SDK's Gradle plugin, version 3.0.1 and earlier, which expects the NDK
to have a MIPS toolchain directory.

解决方案：
一种解决办法是同时升级gradle编译工具的版本。但是因为项目的原因，无法使用最新版本的gradle编译工具，只能使用2.3.0版本的编译工具，所以使用一个绕过问题的方法，
在/Users/Ivonhoe/Library/Android/sdk/ndk-bundle/toolchains/mips64el-linux-android-4.9/prebuilt/darwin-x86_64/bin/目录创建一个mips64el-linux-android-strip的空文件。记得使用chmod 命令修改空文件的执行权限。

React Native apps fail to build since NDK update to r17 (due to missing mipsel-linux-android-4.9 toolchain files)
