新建.so，I with prefix: mips64el-linux-android， Error occurred while communicating with CMake server.

Error:A problem occurred configuring project ':app'.
> No toolchains found in the NDK toolchains folder for ABI with prefix: mips64el-linux-android

在进行 Run with --stacktrace option to get the stack trace.  之后出现：

Error:A problem occurred configuring project ':app'.
> java.lang.NullPointerException (no error message)

说明：Run with --stacktrace option to get the stack trace.  其实就是打印出详细的报错信息，让你查看。

解决：这个直接下载ndk 版本是16的，找到mips64el-linux-android 类似的就行，

直接复制到：C:\Users\Administrator\AppData\Local\Android\sdk\ndk-bundle\toolchains;

Error:A problem occurred configuring project ':app'.
> Error occurred while communicating with CMake server. Check log D:\ceshi\So_ceshi\app\.externalNativeBuild\cmake\debug\armeabi-v7a\cmake_server_log.txt for additional information.

把cmake 中的：3.10 删除 uninstall；
