  15 // Implementation of the Notification UI Manager for Android, which defers to
  16 // the Android framework for displaying notifications.
  17 //
  18 // Android does not support getting the notifications currently shown by an
  19 // app without very intrusive permissions, which means that it's not possible
  20 // to provide reliable implementations for methods which have to iterate over
  21 // the existing notifications. Because of this, these have not been implemented.
  22 //
  23 // The UI manager implementation *is* reliable for adding and canceling single
  24 // notifications based on their delegate id. Finally, events for persistent Web
  25 // Notifications will be forwarded directly to the associated event handlers,
  26 // as such notifications may outlive the browser process on Android.
