Note: Calling build() multiple times returns the same Notification instance, so reusing a builder to create multiple Notifications is discouraged.
| Returns || |----------------------------------------------------------------------------------|-------------------------------------------| | [Notification](https://developer.android.com/reference/android/app/Notification) | the fully constructed Notification
