本文介绍了一个Python脚本，用于解析Android应用的AndroidManifest.xml文件，提取已导出的Activity信息并将其保存到新的XML文件中。该脚本还判断了主Activity，并记录了相关的权限。

XML内容如下：

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

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.dongbao.wauoen.interappactivitytesting" platformBuildVersionCode="23" platformBuildVersionName="6.0-2704002">

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

    <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/AppTheme">

        <activity android:exported="true" android:name="com.dongbao.wauoen.interappactivitytesting.MainActivity">

            <intent-filter>

                <action android:name="android.intent.action.MAIN"/>

                <category android:name="android.intent.category.LAUNCHER"/>

            </intent-filter>

        </activity>

        <activity android:enabled="@bool/use_activity" android:exported="true" android:icon="@drawable/ic_chooser" android:label="@string/choose_file" android:name="com.ipaulpro.afilechooser.FileChooserActivity"/>

        <activity android:exported="true" android:name="com.dongbao.wauoen.interappactivitytesting.ExampleActivity" android:permission="android.permission.READ_EXTERNAL_STORAGE"/>

    </application>

</manifest>

2.解析过程：主要获取开放activity的信息，并保存到xml文件中

from ActivityInfo import ActivityInfo
 
try:

    import xml.etree.cElementTree as ET

except ImportError:

    import xml.etree.ElementTree as ET

import sys
 
# Manifest namespace

namespace = '{http://schemas.android.com/apk/res/android}'
# Exported activities

exported_activities = []
 
# XML analyze

def __xml_analyze__():

    tree = ET.parse(r"./app/AndroidManifest.xml")

    root = tree.getroot()

    # print tree.namespace

    # 1.get package name

    packagename = root.attrib["package"]

    # 2.get exported activity

    application = root.find("application")

    __get_exported_activities__(application, packagename)

    for activity in exported_activities:

        print activity.__get_name__(), activity.__get_package_name__(), activity.__get_permission__()

    # 3.save result to xml file

    __save_result_to_xml__()
 
# get exported activities

def __get_exported_activities__(application, packagename):

    for activity in application:

        # 2.1 MainActivity name

        if __is_main_activity__(activity):

            name = activity.attrib[namespace+'name']

            main_activtiy = ActivityInfo(name)

            main_activtiy.__set_package_name__(packagename)

            if activity.find(namespace+'permission') is not None:

                permission = activity.attrib[name+'permission']

                main_activtiy.__set_permission__(permission)

            exported_activities.append(main_activtiy)

        else:

            # 2.1 exported activities except mainactivtiy

            exported = activity.attrib[namespace+'exported']

            if exported:

                activity_name = activity.attrib[namespace+'name']

                exported_activity = ActivityInfo(activity_name)

                exported_activity.__set_package_name__(packagename)

                permission = activity.attrib.get(namespace+'permission', None)

                if permission is not None:

                    # permission = activity.attrib[name+'permission']

                    # print permission

                    exported_activity.__set_permission__(permission)

                exported_activities.append(exported_activity)
 
# save result to xml file

def __save_result_to_xml__():

    tree = ET.ElementTree()

    root = ET.Element('data')

    tree._setroot(root)

    for activity in exported_activities:

        node = ET.Element('activity')

        node.set('name', activity.__get_name__())

        node.set('packagename', activity.__get_package_name__())

        root.append(node)

        if activity.__get_permission__() is not None:

            node.set('permission', activity.__get_permission__())

    tree.write("output.xml")
 
# the activity is or not MainActivity

def __is_main_activity__(activity):

    intent_filter = activity.find("intent-filter")

    if intent_filter is not None:

        action = intent_filter.find('action')

        category = intent_filter.find('category')

        if action is not None and category is not None \

                and action.attrib[namespace + "name"] == 'android.intent.action.MAIN'\

                and category.attrib[namespace + "name"] == 'android.intent.category.LAUNCHER':

            print 'this is main activity'

            return True

    return False
 
# main fun

if __name__ == "__main__":

    __xml_analyze__()

3.ActivityInfo

class ActivityInfo:
 
    def __init__(self, name):

        self.name = name

        self.package_name = ''

        self.permission = ''
 
    def __set_package_name__(self, package_name):

        self.package_name = package_name
 
    def __get_package_name__(self):

        return self.package_name
 
    def __set_name__(self, name):

        self.name = name
 
    def __get_name__(self):

        return self.name
 
    def __set_permission__(self, permission):

        self.permission = permission
 
    def __get_permission__(self):

        return self.permission
