1.背景

正常开发中，我们大多在window下开发好我们的App，我们需要打包为ApK,然后在我们的手机安装才能运行，官方给出了3种打包方案Buildozer,Python-for-Android,Kivy Launch,当然开发者大多打包在Linux环境，因为我们在Windows下的环境配置比较繁琐，当然官方给了几种方法都是基于Linux的（

https://github.com/kivy/buildozer

官方文档）。

2.Biuldozer打包才是常态

Buildozer打包的好处在于可以自动构建整个打包过程，该工具会自动下载并设置Python-for-Android，包括了Android SDK 和 NDK，这种方式新手最适合（使用这个一个工具，你可以打包IOS,android,osx等）

3.步骤

物理部署

1.安装buildozer

[root@pand_1_2 hello]# pip3 install buildozer -i https://pypi.doubanio.com/simple/

容器化部署(centos7)

1.安装docker

[root@pand_1_2 hello]# pip install DockerDeploy (本人写的，也可以使用官方安装容器方法)

2.安装镜像

[root@pand_1_2 hello]# docker pull kivy/buildozer

3.运行一个容器

docker run -itd --name buildozer --privileged=true --volume "$PWD":/home/user/hostcwd --entrypoint /bin/bash kivy/buildozer

4.进入容器

[root@pand_1_2 hello]# docker exec -it buildozer /bin/bash

共有步骤

修改Python-for-Android代码拉取地址（改为国内源），如下：

[root@pand_1_2 hello]# vim /usr/local/python3/lib/python3.6/site-packages/buildozer/targets/android.py

将kivy改为mirrors，到github.com替换gitee.com

加入环境变量

[root@pand_1_2 hello]# vim ~/.bashrc

    export PATH=$PATH:/usr/local/python3/bin/

[root@pand_1_2 hello]# source ~/.bashrc

即可开始打包

[root@pand_1_2 hello]# buildozer init (生成初始化配置文件，这个配置文件修改请参考官方文档)

[root@pand_1_2 hello]# buildozer android debug

看到如下画面即成功（注意第一次打包很慢，有些需要安装环境，国外网速太慢，也有可能因为网速原因安装失败，需要多试几次，否则就用vpn）

备注:如果存在文件无访问权限，请修改权限即可

[root@pand_1_2 hello]# sudo chmod 777 -R /home

我并没有完全按照官方文档进行部署，因为我希望我经过第一次安装后我的环境不需要重新安装，以后在打包时，就会很快
