lived is a Scala library that aims to manage the android lifecycle of non Activity and Fragment objects.
The Activity or Fragment containing Managed objects needs to respectively extend the ActivityLifecycleManager or FragmentLifecycleManager traits, to delegate lifecycle events.
A Managed will only be lifecycle managed when the containing object is also Managed, a break in this management chain will result in all Managed objects to silently fail, as they wait for the chain to be completed.
The execution of the Lived sub traits will be according to the start of creation of the Managed objects or the inverse for destructing lifecycle events like Pausable.
ActivityLike, Creatable, Startable, Resumable, Pausable, Stoppable and Destroyable are traits that can get Managed in an object contained in an Activity that extends the ActivityLifecycleManager trait.
FragmentLike, ActivityLike, Creatable, CreateViewable, Attachable, Startable, Resumable, ActivityCreatedable, Detachable, DestroyViewable, Pausable, Stoppable and Destroyable are traits that can get Managed in an object contained in an Fragment that extends the FragmentLifecycleManager trait.
