Hello! , I am starting a new Activity by using

startActivity(intent)

and

finish()

, but my viewModel

onCleared()

method is not called . What is the reason. I am using koin for di. Appcompat library 'com.android.support😒upport-v4:27.1.1' .

Probably your activity leaked

But onDestroy is called for the activity.

Activity still can be alive. Not sure how ViewModel behaves in this case (activity lifecycle in destroyed state, but activity leaked)

How can I find if that's the case. Can you suggest me ways to proceed from here

Maybe you could debug your code or check memory dump to check this theory

Afaik the ViewModels are (by default, but you can change that) bound to a store owned by a retained Fragment, which lives beyond the lifecycle of the Activity instance (to survive configuration changes). Only when the retained fragment is destroyed will you see `onCleared()`invoked.

@Udit003 LeakCanary identifies finished activity with active references to it. Can you share a github project reproducing the issue?

Sorry guys, Actually it was a silly mistake by me. Rather than injecting the viewmodel using

by viewModel()

, I used

by inject()

. Because of which koin was not able to attach the viewmodel to the lifecycle of activity. But thanks for all your suggestions. In the debugging process, I got introduced to LeakCanary, so it was helpful.

@Udit003 I have it enabled it always in Debug builds, helps find out regressions as they occur. But it can't catch all kinds of memory usage issues.
