Python——使用ElementTre

- 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
