PackageItemInfo

public class PackageItemInfo
extends Object

java.lang.Object
   ↳ android.content.pm.PackageItemInfo
Known Direct Subclasses
Known Indirect Subclasses

包含包管理器保存的所有包项的公共信息的基类。 这提供了一组非常常见的基本属性：标签，图标和元数据。 本课程不打算单独使用; 只是在这里共享包管理器返回的所有项目之间的通用定义。 因此，它本身并不实现Parcelable，但确实提供了便利的方法来帮助在子类中实现Parcelable。
