Python如何通过subprocess调用adb命令详解

前言

本文主要给大家介绍了关于使用Python通过subprocess调用adb命令，subprocess包主要功能是执行外部命令（相对Python而言）。和shell类似。

换言之除了adb命令外，利用subprocess可以执行其他的命令，比如ls，cd等等。

subprocess 可参考： https://docs.python.org/2/library/subprocess.html

在电脑上装好adb工具，配置好adb的环境变量，先确保shell中可以调用adb命令。

代码示例

Python2.7

类 Adb，封装了一些adb的方法

import os
import subprocess
class Adb(object):
""" Provides some adb methods """
@staticmethod
def adb_devices():
 """
 Do adb devices
 :return The first connected device ID
 """
 cmd = "adb devices"
 c_line = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE).communicate()[0]
 if c_line.find("List of devices attached") < 0: # adb is not working
  return None
 return c_line.split("\t")[0].split("\r\n")[-1] # This line may have different format
@staticmethod
def pull_sd_dcim(device, target_dir='E:/files'):
 """ Pull DCIM files from device """
 print "Pulling files"
 des_path = os.path.join(target_dir, device)
 if not os.path.exists(des_path):
  os.makedirs(des_path)
 print des_path
 cmd = "adb pull /sdcard/DCIM/ " + des_path
 result = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE).communicate()
 print result
 print "Finish!"
 return des_path
@staticmethod
def some_adb_cmd():
 p = subprocess.Popen('adb shell cd sdcard&&ls&&cd ../sys&&ls',
       stdout=subprocess.PIPE, stderr=subprocess.PIPE)
 return_code = p.poll()
 while return_code is None:
  line = p.stdout.readline()
  return_code = p.poll()
  line = line.strip()
  if line:
   print line
 print "Done"

some_adb_cmd方法执行一连串的命令。各个命令之间用&&连接。

接着是一个死循环，将执行结果打印出来。
