我正在尝试使用https://github.com/shadowsocks/shadowsocks-android
为了运行它，我遵循所有的指示
已安装：
JDK 1.8
Go 1.11+
Android SDK
Android NDK r16+
为了设置路径，我在系统的.profile文件中这样做：
JAVA_HOME=/usr/lib/jvm/jdk1.8.0_181
PATH=$PATH:$JAVA_HOME/bin
export JAVA_HOME
export JRE_HOME
export PATH
export GOROOT=/home/optimumanddev2/Downloads/go
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
export ANDROID_HOME=/home/optimumanddev2/Android/Sdk
export PATH=${PATH}:~/Android/Sdk/tools:~/Android/Sdk/platform-tools
export ANDROID_NDK_HOME=$ANDROID_HOME/ndk-bundle
在那之后，我从github下载了最新的代码并试图构建它，但是它给出了以下错误：

请帮忙，我认为路径设置过程可能是错误的。

# Import cpufeatures
$(call import-module,android/cpufeatures)
在我的项目中缺少的文件：
例如（core/.externalNativeBuild/ndkBuild/debug/armeabi-v7a），这些文件夹是空的。我想这可能是问题所在。
因为在我的另一个NDK项目中，这些文件夹有文件和一些代码
最佳答案
这个错误是在我用git命令正确地克隆了项目之后解决的，如https://github.com/shadowsocks/shadowsocks-android.git
因此，要删除NDK错误，需要安装并设置所有必需内容的路径，并正确克隆，以便可以正确克隆所有子文件夹，这些错误是由于文件不可用而导致的。
但我也有其他错误，比如库冲突：
错误“Program type already present”android.support.customtabs
