apk包中的AndroidManifest.xml文件包含了package的各种描述信息. 分析和获取这些信息的工作是由PackageParser完成的. 这里简述之. 首先我们先罗列AndroidManifest.xml文件的简要结构, 其次在大致整理PackageParser的逻辑.
AndroidManifest.xml的简要结构====================================
AndroidManifest.xml的内容在frameworks/base/core/res/res/values/attrs_manifest.xml中定义. 这里简要罗列, 按照层进关系, xml element用 "tagName, Name"的形式标记, 对于某些xml element的重要属性(attribute), 用"attr NAME"标记.
AndridManifest.xml
manifest, AndroidManifest
attr versionCode
attr versionName
attr sharedUserId
attr sharedUserLabel
attr installLocation
permission, AndroidManifestPermission

attr name, label, icon
attr targetActivity
attr permission
attr enabled, exported
uses-library, AndroidManifestUsesLibrary
attr name
attr required
instrumentation, AnroidManifestInstrumentation
attr name, label, icon
attr targetPackage, handleProfiling
attr functionalTest
uses-feature, AndroidManifestUsesFeature
attr glEsVersion
attr name
attr required
supports-screens, AndroidManifestSupportsScreens
attr smallScreens, normalScreens, largeScreens
attr resizeable, anyDensity
protected-broadcast, AndroidManifestProtectedBroadcast
attr name
adopt-permissions, AndroidManifestOriginalPackage
attr name
还有几个特别的xml element, 可以有多个parent element.
application
activity, receiver, provider, service
permission, permissionGroup
instrumentation
meta-data, AndroidManifestMetaData
attr name, value, resource
activity, receiver, service
intent-filter, AndroidManifestIntentFilter
attr label, icon, priority
action, AndroidManifestAction
attr name
data, AndroidManifestData
attr mimeType, scheme, host
attr port, path, pathPrefix
attr pathPattern
category, AndroidManifestCategory
attr name
intent, Intent
attr action, data, mimeType
attr targetPackage, targetClass
category, IntentCategory
attr name
extra, Extra
attr name, value
PackageParser的逻辑====================================
PackageParser的parsePackage()方法会读取apk包中的AndroidManifest.xml文件, 调用各子par***XX()方法, 解析出包信息. 同时, PackageParser定义了一些class, 容纳这些解析得到的信息. 下面是对应的关系.
class xml elements
------------- --------------------------------------
Package package
Permission permission, permission-tree
PermissionGroup permission-group
Activity activity, activity-alias, receiver
Service service
Provider provider
Instrumentation instrumentation
ActivityIntentInfo intent-filter @ activity or receiver
ServiceIntentInfo intent-filter @ service
PacakgeParser的结果主要被PackageManagerService使用.
