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:

# 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"])

return o
