How to use Room Database Viewmodel Observer in Android Foreground Service

Question

I have following view model and observer in A Fragment(in onViewCreated) which populates the recyelerview using adapter

commonOwnDBViewModel =
                new ViewModelProvider(requireActivity()).get(CommonOwnDBViewModel.class);
        Observer<List<FolderEntity>> notesObserver =
                FolderEntityList -> {
                    folderNameAdapter.setListManager(FolderEntityList);
                    recyclerView.getAdapter().notifyDataSetChanged();
                    Toast.makeText(mActivity, "" + FolderEntityList.size(), Toast.LENGTH_SHORT).show();
                };
        commonOwnDBViewModel.getAllFolderEntityList
                ().observe(requireActivity(), notesObserver);

it gives me a list and works fine in the fragment now I want to use the same list in A service using Viewmodel and Observer how can we do that how do we manage Lifecycle in service.

Instead of using normal service, use LifecycleService.

You can get the lifecycle of the service by calling getLifecycle() method and pass this lifecycle to your observer.

so should we use commonOwnDBViewModel = new ViewModelProvider(getLifecycle()).get(CommonOwnDBViewModel.class); ?? – 1234567 Oct 18 '21 at 06:23
