android开发调⽤python脚本
⼀.环境准备
在官⽹下载最新的CLE for Android 开发包，其中包含⽰例⼯程和API⽂档。解压开发包，拷贝如下⽂件
重点：这种⽅式如果是第三⽅或者是android 环境运⾏不了的插件就不适⽤了，只适⽤⼀些简单的插件
你可能会遇到的问题
1：注意so版本；版本都要⼀致，从开发包⾥复制粘贴；
2：注意so引⼊路径；as和ec是有区别的；
拷贝 starcore_android_rX.X.jar的arm64-v8a⽬录内容到⼯程的libs⽬录
拷贝starcore_android_rX.X.jar的到starcore_android_r3.7.dex、starcore_android_r3.7.jar到libs⽬录,
asset中的so在android.python.3.4.5.zip包和android.python.3.7.0.zip包解压出来的，
如下图：
libs的和assets⾥⾯的so；
⼆、编写Python代码
test.py⽂件内容如下：
def add(x,y) :
return x+y
calljava.py内容如下：
import imp #test load path
def log(content):
JavaClass.d("formPython",content)
log("Hello Android,form python")
py_code.py内容如下：
import time
def get_time():
return time.time()
将py_code.py压缩为py_code.zip⽂件。将编写的Python源码放⼊Android ⼯程的assets⽬录，其中还要包含⼀些Python需要的环境及标准库（android.python.3.7.0⾥⾯arm64-v8a\lib-dynload中到对应的so库），见下图
三、编写Android相关代码，初始化CLE并调⽤Python
