1、在调用ElementTree.parse之前一定要想调用以下代码：
uri = "http://schemas.android.com/apk/res/android"
ElementTree.register_namespace("android", uri)
要是没有调用上述代码注册namespace，在调用 tree.write将xml写回去时候，android:会被替换为ns0:
2、获取某个标签的属性时候，可以用以下两种方式：（以获取包名为例）
1）packageName = root.get('package')
2) packageName = root.attrib['package']
3、添加某个节点时，注意属性与namespace的设置：
以添加以下meta-data为例：
<meta-data android:name="android.max_aspect" android:value="2.1"/>
ElementTree的实现代码：
namespace = "{http://schemas.android.com/apk/res/android}"
tree = ElementTree.parse(androidManifestPath)
root = tree.getroot()
application = root.find("application")
max_aspect = Element("meta-data", attrib={namespace + 'name': "android.max_aspect", namespace + 'value': "2.1"})
max_aspect.tail = "\n\t"
application.append(max_aspect)
tree.write(androidManifestPath,encoding="UTF-8")
4、替换某个字符串（注意：xml读出来再写回去会少了<?xml version="1.0" encoding="utf-8"?>）
newContents = []
newContents.append('<?xml version="1.0" encoding="utf-8"?>')
newContents.append("\n")
with open(androidManifestPath, "r", errors='ignore') as file:
contents = file.read()
newContents.append(contents.replace("{applicationId}", packageName).replace("singleTask", "singleTop"))
with open(androidManifestPath, "w", errors='ignore') as f:
f.writelines(newContents)
f.flush()

示例代码：
# 修改AndroidManifest.xml对应配置
def changeCommonAndroidManifest(androidManifestPath,appName,packageName,versionCode,versionName,sswlAppId,urlHost):

# 注意声明register_namespace，要不write写回去时候android会被替换为ns0
uri = "http://schemas.android.com/apk/res/android"
namespace = "{http://schemas.android.com/apk/res/android}"
key = namespace + 'name'
# 替换跟sdk包名相关的字符串,以及将有些游戏设置为singleTask的启动模式改为singleTop
