Python脚本获取app应用相关信息

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：

    # 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"

        if output != "":

        result = ""
        p = subprocess.Popen(cmd, stdout=subprocess.PIPE,
                             stderr=subprocess.PIPE,

        if output != "":
            result = output.split()[1][6:-1]
        return result

    # 得到启动类

        result = ""
        p = subprocess.Popen(cmd, stdout=subprocess.PIPE,
                             stderr=subprocess.PIPE,

        return result


if __name__ == '__main__':
    apkInfo = ApkInfo()
    print("应用名称:", apkInfo.get_apk_name())
    print("app文件大小:", apkInfo.get_apk_size())
    print("app版本信息:", apkInfo.get_apk_version())
    print("app包名:", apkInfo.get_apk_package())
    print("app的启动类:", apkInfo.get_apk_activity())

结果
