一脸懵逼

• 尝试修正

根据网上的链接

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

以及原来的NDK版本，都指向要用r10版本！
从历史版本里面可以下载，不过已经不再支持了

过了这个错误，不过又有其他错误了！只能升级gradle到4.X.X

结果报错NDK not supported (pre-r11)了！

• 最终修改

偶然一次修改，我把NDK重新改成20.0.5594570，这种意外编译成功了。
原来我r10版本还白白下载了。

看来gradle到版本应该还和NDK是有关联关系的。升级了gradle，那么我NDK的版本也应该是“配套升级”

特意列出来也是为以后的老项目的编译增加经验
