apk包中的AndroidManifest.xml文件包含了package的各種描述信息. 分析和獲取這些信息的工作是由PackageParser完成的. 這里簡述之. 首先我們先羅列AndroidManifest.xml文件的簡要結(jié)構(gòu), 其次在大致整理PackageParser的邏輯.
AndroidManifest.xml的簡要結(jié)構(gòu)
====================================
AndroidManifest.xml的內(nèi)容在frameworks/base/core/res/res/values/attrs_manifest.xml中定義. 這里簡要羅列, 按照層進(jìn)關(guān)系, xml element用 "tagName, Name"的形式標(biāo)記, 對于某些xml element的重要屬性(attribute), 用"attr NAME"標(biāo)記.

還有幾個特別的xml element, 可以有多個parent element.

PackageParser的邏輯
====================================
PackageParser的parsePackage()方法會讀取apk包中的AndroidManifest.xml文件, 調(diào)用各子par***XX()方法, 解析出包信息. 同時, PackageParser定義了一些class, 容納這些解析得到的信息. 下面是對應(yīng)的關(guān)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的結(jié)果主要被PackageManagerService使用.
