adb command python call phone operating

Python can be used in executing cmd command os and subprocess two modules.

The difference is that is blocking the os, subprocess is non-blocking, so we generally use the subprocess is more appropriate.

Next, I first give a command to query the connected device and see how kind of written in python. Command used to adb devices.

 

method one:

import os

os.system ( 'adb devices') # connection apparatus acquires

 

operation result

List of devices attached

Q8DCGQA6JBQRSAI device

 

Second way:

import subprocess

order = 'adb devices' # Get connected device

pi= subprocess.Popen(order,shell=True,stdout=subprocess.PIPE)

print (pi.stdout.read ()) # print results

 

operation result

b'List of devices attached\r\AQ8DCGQA6JBQRSAI\tdevice\r\n\r\n'
