Getting the adb output using Python

Question

I\'m trying to get the output of a adb command using the following code:

pathCmd = \'./adb shell pm path \' + packageName


pathData = subprocess.Popen(pathC         


        

Answer 1

You should use check_output, below is my code which works successfully.

from subprocess import check_output, CalledProcessError

from tempfile import TemporaryFile

def __getout(*args):
    with TemporaryFile() as t:
        try:
            out = check_output(args, stderr=t)
            return  0, out
        except CalledProcessError as e:
            t.seek(0)
            return e.returncode, t.read()

# cmd is string, split with blank
def getout(cmd):
    cmd = str(cmd)
    args = cmd.split(' ')
    return __getout(*args)

def bytes2str(bytes):
    return str(bytes, encoding='utf-8')

def isAdbConnected():
    cmd = 'adb devices'
    (code, out) = getout(cmd)
    if code != 0:
        print('something is error')
        return False
    outstr = bytes2str(out)
    if outstr == 'List of devices attached\n\n':
        print('no devices')
        return False
    else:
        print('have devices')
        return True

Call isAdbConnected() to check whether device is connected. Hope to help you.

Answer 2

from subprocess import Popen, PIPE

with Popen(['adb devices'], shell=True,stdout=PIPE) as proc:
    for val in proc.stdout.readlines()[1:-1]:
        print(val.decode('UTF-8').replace('device', '').strip())

import subprocess

ADB_PATH="adb"

def adbdevices(adbpath=ADB_PATH):
    return set([device.split('\t')[0] for device in subprocess.check_output([adbpath, 'devices']).splitlines() if device.endswith('\tdevice')])

def adbshell(command, serial=None, adbpath=ADB_PATH):
    args = [adbpath]
    if serial is not None:
        args.extend(['-s', serial])
    args.extend(['shell', command])
    return subprocess.check_output(args)

def pmpath(pname, serial=None, adbpath=ADB_PATH):
    return adbshell('pm path {}'.format(pname), serial=serial, adbpath=adbpath)
