Wrapper script for working with adb and multiple Android devices

Readme.md

Usage

$set_android_device.py adb shell
(1) - R32D3006XXX [device usb:3-1.1 product:mantaray model:Nexus_10 device:manta]
(2) - 01499EAD0701XXXX [device usb:3-1.4 product:yakju model:Galaxy_Nexus device:maguro]
2
shell@maguro:/ $ 

How it works

• The script reads all available devices through adb and let you chose one.
• It set the environment variable ANDROID_SERIAL to the selected device
• Executes the command that is attached throught the arguments

set_android_device.py

#!/usr/bin/env python
import subprocess
import sys
import os

def parse_device_list(str):
    raw_list = filter(None, str.splitlines())[1:]
    devices = []
    for raw_device in raw_list:
        parts = raw_device.split()
        devices.append((parts[0], " ".join(parts[1:])))
    return devices

def get_device_list():
    p = subprocess.Popen(['adb', 'devices', '-l'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
    out, err = p.communicate()
    if len(err) == 0:
        return parse_device_list(out)
    else:
        return

devices = get_device_list()

if devices == None:
    print("Could not find any device")
    sys.exit(1)

for i in range(len(devices)):
    id, name = devices[i]
    print("(%d) - %s [%s]" % (i+1, id, name))

def num(s):
    try:
        return int(s)
    except exceptions.ValueError:
        return


while True:
    choosen = num(sys.stdin.readline())
    if (choosen != None and choosen > 0 and choosen <= len(devices)):
        break

os.environ['ANDROID_SERIAL'] = devices[choosen - 1][0]

p = subprocess.Popen(sys.argv[1:])
try:
	p.communicate()
except KeyboardInterrupt:
	pass
