使用Python中的AndroidManifest.XML打印服务和接收器

Question

我正在尝试打印Python中Android Manifest文件中使用的所有权限，功能，最小sdk版本，服务，内容提供商，广播接收器。 我编写了一个可以打印权限和功能的代码，但是在打印服务和内容提供程序时它显示为空值。

这是我的Android Manifest Code：

<?xml version="1.0" encoding="utf-8" standalone="no"?>

这是Python代码：

import xml.etree.ElementTree as ET

root = ET.parse("AndroidManifest.xml").getroot()

var = root.findall("uses-permission")
#print(var)
n=len(var)
for i in range(n):
 print(var[i].attrib)


var1 = root.findall("uses-feature")
#print(var1)
m=len(var1)
for j in range(m):
 print(var1[j].attrib)


var2 = root.findall("application")
#print(var2)
a=len(var2)
for k in range(a):
 print(var2[k].attrib)


var3 = root.findall("service")
print(var3)

b=len(var3)
for v in range(b):
  print(var3[v].attrib)

此代码可以打印Manifest文件使用的权限，功能，但不能打印使用的服务。可能是什么问题？我在哪里弄错了？
