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."

  1. https://github.com/uber/AutoDispose#autodispose AutoDispose • From Uber Technologies • “RxJava 2 tool

    for automatically binding the execution of RxJava 2 streams to a provided scope“ • Architecturally better version of RxLifecycle
  2. CompositeDisposable private val disposables = CompositeDisposable() override fun onCreate(savedInstanceState: Bundle?)

    { super.onCreate(savedInstanceState) ... myObservable.doStuff() .subscribeBy { ... } .addTo(disposables) } override fun onDestroy() { disposables.dispose() super.onDestroy() }
  3. CompositeDisposable private val disposables = CompositeDisposable() override fun onCreate(savedInstanceState: Bundle?)

    { super.onCreate(savedInstanceState) ... myObservable.doStuff() .subscribeBy { ... } .addTo(disposables) } override fun onDestroy() { disposables.dispose() super.onDestroy() }
  4. CompositeDisposable private val disposables = CompositeDisposable() override fun onCreate(savedInstanceState: Bundle?)

    { super.onCreate(savedInstanceState) ... myObservable.doStuff() .subscribeBy { ... } .addTo(disposables) } override fun onDestroy() { disposables.dispose() super.onDestroy() }
  5. CompositeDisposable private val disposables = CompositeDisposable() override fun onCreate(savedInstanceState: Bundle?)

    { super.onCreate(savedInstanceState) ... myObservable.doStuff() .subscribeBy { ... } .addTo(disposables) } override fun onDestroy() { disposables.dispose() super.onDestroy() }
  6. 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
  7. 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
  8. 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
