To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function. I also tried with nav_graph but i put bottom navigation in MainFragment and when i choose another fragment bottom navigation disappeared. The Problem: On some devices, pressing the launcher icon results in the current task being resumed, on others it results in the initial launch intent being fired (effectively restarting the app). Depending on the users Android device, this button might be a physical button or a software button. OnBackPressedDispatcher: As a composable alternative to overriding onBackPressed(), you can now register a OnBackPressedCallback from any LifecycleOwner (such as a fragment) to intercept system back button communication between fragments should be done through the associated Activity. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function. 2- All the fragments willing to intercept the BackPress event had to implement the interface above which caused them having the onBackPressed() function call.

To do this, we're going to create an Activity that creates a ReactRootView, starts a React application inside it and sets it as the main content view..

Now the fragment can respond to BackPress events and do something and based on if the event was consumed This is a no-op, but it indicates a memory leak in your application.
