Windows 中 使用python 一鍵下載android r代碼

爲了在window方便看代碼，所以下載google原生android r代碼，寫了一段python腳本方便下載

1.  安裝GIT

git官網下載：https://git-scm.com/downloads/

安裝git到如下路徑  C:/Program Files/Git

2.  安裝PYTHON

python官網下載：https://www.python.org/downloads/

安裝python到如下路徑 C:/Program Files/python

3.  下載代碼

拷貝如下腳本保存到本地到文件download_android_r.py，使用cmd命令行進入到剛剛下載文件的目錄執行python download_android_r.py下載代碼到本地目錄
