Python 调用adb命令

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。

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。

subprocess 说明

creationflags=CREATE_NEW_CONSOLE在执行指令时弹出一个新的cmd窗口

可以执行指定的bat脚本
