Content sharing ({@link android.content})
  For sharing content between application components. The most important classes are:
  - {@link android.content.ContentProvider} and {@link android.content.ContentResolver} for managing and publishing persistent data associated with an application.
  - {@link android.content.Intent} and {@link android.content.IntentFilter}, for delivering structured messages between different application components—allowing components to initiate other components and return results.
Package management ({@link android.content.pm})
  For accessing information about an Android package (an {@code .apk}), including information about its activities, permissions, services, signatures, and providers. The most important class for accessing this information is {@link android.content.pm.PackageManager}.
Resource management ({@link 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 {@link android.content.res.Resources}.
