今天跟大家分享一下，如何通過Python實現(xiàn)一個輕量級的庫來獲取電腦上連接的Android設(shè)備信息，為什么說輕量呢因為整個庫也就4KB，相比其他諸如Appetizer這樣動輒就8MB多的庫要輕很多，而且也基本滿足項目中的需求。

這個庫只有一個文件，通過封裝Android的ADB命令實現(xiàn)，返回的是一個包含所有設(shè)備信息的標準json格式的列表方便解析，下面簡單介紹一下：

檢查環(huán)境變量

# 判斷是否設(shè)置環(huán)境變量ANDROID_HOMEif "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"])

命令執(zhí)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命令封裝

class ADB(object):  """   參數(shù): 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):    """    獲取設(shè)備狀態(tài)： offline | bootloader | device    """    return self.adb("get-state").stdout.read().strip()  def get_device_id(self):    """    獲取設(shè)備id號，return serialNo    """    return self.adb("get-serialno").stdout.read().strip()  def get_android_version(self):    """    獲取設(shè)備中的Android版本號，如4.2.2    """    return self.shell(      "getprop ro.build.version.release").strip()  def get_sdk_version(self):    """    獲取設(shè)備SDK版本號，如：24    """    return self.shell("getprop ro.build.version.sdk").strip()  def get_product_brand(self):    """    獲取設(shè)備品牌，如：HUAWEI    """    return self.shell("getprop ro.product.brand").strip()  def get_product_model(self):    """    獲取設(shè)備型號，如：MHA-AL00    """    return self.shell("getprop ro.product.model").strip()  def get_product_rom(self):    """    獲取設(shè)備ROM名，如：MHA-AL00C00B213    """    return self.shell("getprop ro.build.display.id").strip()

設(shè)備信息獲取

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_versionclass 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
