Code Samples

Java

myObservable
    .map(...)
    .as(AutoDispose.autoDisposable(AndroidLifecycleScopeProvider.from(this)))
    .subscribe(...)

Kotlin

myObservable
    .map(...)
    .autoDisposable(AndroidLifcycleScopeProvider.from(this))
    .subscribe(...)

With Scope Event Provided

myObservable
    .map(...)
    .autoDisposable(AndroidLifcycleScopeProvider.from(this, Lifecycle.Event.ON_DESTROY))
    .subscribe(...)

Testing

// File: CustomerService.kt
class CustomerService @Inject constructor(...) {
    lateinit var scopeProvider: ScopeProvider
}

// Usage in Fragment/Activity/etc
val service = CustomerService(...).apply {
    scopeProvider = AndroidLifecycleScopeProvider.from(this)
}

// Usage in Test
val service = CustomerService(...).apply {
    scopeProvider = TestScopeProvider.create()
}
