通过Python 获取Android设备信息的轻量级框架

今天跟大家分享一下，如何通过Python实现一个轻量级的库来获取电脑上连接的Android设备信息，为什么说轻量呢因为整个库也就4KB，相比其他诸如Appetizer这样动辄就8MB多的库要轻很多，而且也基本满足项目中的需求。

这个库只有一个文件，通过封装Android的ADB命令实现，返回的是一个包含所有设备信息的标准json格式的列表方便解析，下面简单介绍一下：

检查环境变量

# 判断是否设置环境变量ANDROID_HOME
if "ANDROID_HOME" in os.environ:
  command = os.path.join(
    os.environ["ANDROID_HOME"],
    "platform-tools",
    "adb")
else:
  raise EnvironmentError(
    "Adb not found in $ANDROID_HOME path: %s." %
    os.environ["ANDROID_HOME"])

命令执行

class Shell:
  def __init__(self):
    pass
  @staticmethod
  def invoke(cmd):
    output, errors = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE).communicate()
    o = output.decode("utf-8")
    return o

ADB命令封装

class ADB(object):
  """
   参数: device_id
  """
  def __init__(self, device_id=""):
    if device_id == "":
      self.device_id = ""
    else:
      self.device_id = "-s %s" % device_id
  def adb(self, args):
    cmd = "%s %s %s" % (command, self.device_id, str(args))
    return Shell.invoke(cmd)
  def shell(self, args):
    cmd = "%s %s shell %s" % (command, self.device_id, str(args),)
    return Shell.invoke(cmd)
  def get_device_state(self):
    """
    获取设备状态： offline | bootloader | device
    """
    return self.adb("get-state").stdout.read().strip()
  def get_device_id(self):
    """
    获取设备id号，return serialNo
    """
    return self.adb("get-serialno").stdout.read().strip()
  def get_android_version(self):
    """
    获取设备中的Android版本号，如4.2.2
    """
    return self.shell(
      "getprop ro.build.version.release").strip()
  def get_sdk_version(self):
    """
    获取设备SDK版本号，如：24
    """
    return self.shell("getprop ro.build.version.sdk").strip()
  def get_product_brand(self):
    """
    获取设备品牌，如：HUAWEI
    """
    return self.shell("getprop ro.product.brand").strip()
  def get_product_model(self):
    """
    获取设备型号，如：MHA-AL00
    """
    return self.shell("getprop ro.product.model").strip()
  def get_product_rom(self):
    """
    获取设备ROM名，如：MHA-AL00C00B213
    """
    return self.shell("getprop ro.build.display.id").strip()

设备信息获取

class DeviceInfo:
  def __init__(self, uid, os_type, os_version, sdk_version, brand, model, rom_version):
    self.uid = uid
    self.os_type = os_type
    self.os_version = os_version
    self.sdk_version = sdk_version
    self.brand = brand
    self.model = model
    self.rom_version = rom_version
class Device:
  def __init__(self):
    pass
  @staticmethod
  def get_android_devices():
    android_devices_list = []
    android_devices_infos = []
    for device in Shell.invoke('adb devices').splitlines():
      if 'device' in device and 'devices' not in device:
        device = device.split('\t')[0]
        android_devices_list.append(device)
    for device_uid in android_devices_list:
      device_info = DeviceInfo(device_uid, "Android", ADB(device_uid).get_android_version(),
                   ADB(device_uid).get_sdk_version(),
                   ADB(device_uid).get_product_brand(), ADB(device_uid).get_product_model(),
                   ADB(device_uid).get_product_rom())
      android_devices_infos.append(device_info.__dict__)
    return android_devices_infos

设备信息数据结构

[
  {
    "uid": "BY2WKN1519078327",
    "rom_version": "Che2-UL00 V100R001CHNC00B287",
    "brand": "Honor",
    "os_version": "4.4.2",
    "sdk_version": "19",
    "os_type": "Android",
    "model": "Che2-UL00"
  },
  {
    "uid": "GWY0217414001213",
    "rom_version": "MHA-AL00C00B213",
    "brand": "HUAWEI",
    "os_version": "7.0",
    "sdk_version": "24",
    "os_type": "Android",
    "model": "MHA-AL00"
  }
