I have a custom lifecycle owner which is different to the library one because it uses the pre events due to different reasons:
class ControllerLifecycleOwner<T>(lifecycleController: T) : LifecycleOwner where T : Controller, T : LifecycleOwner {
private val lifecycleRegistry: LifecycleRegistry = LifecycleRegistry(lifecycleController)
init {
lifecycleController.addLifecycleListener(object : LifecycleListener {
override fun preContextAvailable(controller: Controller) {
lifecycleRegistry.handleLifecycleEvent(Event.ON_CREATE)
}
override fun preCreateView(controller: Controller) {
lifecycleRegistry.handleLifecycleEvent(Event.ON_START)
}
override fun preAttach(controller: Controller, view: View) {
lifecycleRegistry.handleLifecycleEvent(Event.ON_RESUME)
}
override fun postDetach(controller: Controller, view: View) {
lifecycleRegistry.handleLifecycleEvent(Event.ON_PAUSE)
}
override fun postDestroyView(controller: Controller) {
lifecycleRegistry.handleLifecycleEvent(Event.ON_STOP)
}
override fun postDestroy(controller: Controller) {
lifecycleRegistry.handleLifecycleEvent(Event.ON_DESTROY)
}
})
}
override fun getLifecycle(): Lifecycle = lifecycleRegistry
}
I'm now seeing crashes in postDestroy:

I'm now seeing crashes in
postDestroy:The corresponding source is: https://android.googlesource.com/platform/frameworks/support/+/refs/heads/androidx-master-dev/lifecycle/lifecycle-runtime/src/main/java/androidx/lifecycle/LifecycleRegistry.java#263
So it seems all the above events were never called but postDestroy.
