android.content

---

Contains classes for accessing and publishing data on a device. It includes three main categories of APIs:

Content sharing (android.content)
For sharing content between application components. The most important classes are:
• ContentProvider and ContentResolver for managing and publishing persistent data associated with an application.
• Intent and IntentFilter, for delivering structured messages between different application components—allowing components to initiate other components and return results.
Package management (android.content.pm)
For accessing information about an Android package (an .apk), including information about its activities, permissions, services, signatures, and providers. The most important class for accessing this information is PackageManager.
Resource management (android.content.res)
For retrieving resource data associated with an application, such as strings, drawables, media, and device configuration details. The most important class for accessing this data is Resources.
