Introduction to AutoDispose

If you use RxLifecycle, maybe now is the time to switch from it to AutoDispose.

"AutoDispose is an RxJava 2 tool for automatically binding the execution of RxJava 2 streams to a provided scope via disposal/cancellation."

21. LifecycleOwner
22. Extension Functions @CheckReturnValue inline fun LifecycleOwner.scope(): LifecycleScopeProvider<*> = AndroidLifecycleScopeProvider.from(this) @CheckReturnValue inline fun LifecycleOwner.scope(untilEvent: Lifecycle.Event): LifecycleScopeProvider<*> = AndroidLifecycleScopeProvider.from(this, untilEvent) // autodispose-android-archcomponents-kotlin
23. AutoDispose with Arch Lifecycle protected val scope: LifecycleScopeProvider<Lifecycle.Event> by lazy { AndroidLifecycleScopeProvider.from(this) // or scope() }) … store.myState.autoDisposable(scope).subscribeBy(onNext = { … }) // Activity.kt
