## 前言 ##

### appt ###

aapt即Android Asset Packaging Tool，在SDK的build-tools目录下。该工具可以查看，创建， 更新ZIP格式的文档附件(zip, jar, apk),也可将资源文件编译成二进制文件。aapt 命令可应用于查看apk包名、主activity、版本等很多信息。

### Popen ###

Popen()可以执行shell命令，并读取此命令的返回值；当我们需要调用系统的命令的时候，最先考虑的os模块。用os.system()和os.popen()来进行操作。但是这两个命令过于简单，不能完成一些复杂的操作，如给运行的命令提供输入或者读取命令的输出，判断该命令的运行状态，管理多个命令的并行等等。这时subprocess中的Popen命令就能有效的完成我们需要的操作。

Popen它的构造函数如下：

subprocess.Popen(args, bufsize=0, executable=None, stdin=None, stdout=None, stderr=None, preexec\_fn=None, close\_fds=False, shell=False, cwd=None, env=None, universal\_newlines=False, startupinfo=None, creationflags=0)

## 代码 ##

前面我们已经谈过如何获取app应用信息的命令，及使用Python中的subprocess.Popen()方法执行shell命令。下面直接进入正题上代码：

# coding=utf-8
    __author__ = "Enoch"
    
    """
    apkInfo app的相关参数信息
    
    """
    from math import floor
    import os
    import subprocess
    
    
    class ApkInfo:
        # 待测试应用路径
        apkPath = "F:\\kaoyan.apk"
    
        def __init__(self):
            self.aapt = "D:\\ProgramFiles\\android-sdk-windows\\build-tools\\28.0.3\\aapt dump badging "
    
        # 获取app的文件大小
        def get_apk_size(self):
            size = floor(os.path.getsize(self.apkPath)/(1024*1000))
            return str(size) + "M"
    
        # 获取app的版本信息
        def get_apk_version(self):
            cmd = self.aapt + self.apkPath

            return result
    
        # 得到启动类
        def get_apk_activity(self):

    if __name__ == '__main__':
        apkInfo = ApkInfo()
