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" } ]
