Class LifecycleOnDestroyHelper

java.lang.Object

io.grpc.binder.LifecycleOnDestroyHelper

public final class LifecycleOnDestroyHelper
extends java.lang.Object

Helps work around certain quirks of Lifecycle.addObserver(androidx.lifecycle.LifecycleObserver) and Lifecycle.State.DESTROYED.

In particular, calls to Lifecycle.addObserver(LifecycleObserver) are silently ignored if the owner is already destroyed.
