            I experienced the same thing. What is currently happening is:-

            1.) App Startup is kinda slow
            2.) App is glitchy upon start

            The good news is:-

            1.) The glitches only happen for the first few times you run the animation,
            2.) The glitches seem to disappear from every element after you break one of the elements in.

            The bad news is of course, you have to repeat the above steps upon EVERY startup. I have heard that running the production builds instead of the debug variants boosts up the performance significantly. As of now, there's nothing you can do about it. It will only break in as Compose develops. You can check the official Compose Samples too. They are as glitchy as your apps.

            All you can really do at this point is wait.

            EDITS BASED ON THE COMMENTS BELOW:-

            1.) By The glitches seem to disappear from every element after you break one of the elements in., I mean that if you have a lot of animated content, like maybe two LazyColumns, and a few others, then upon swiping the Column back and forth a few times (breaking it in), the lag will be gone from the other columns, as well as the animated content. Element there meant element of the screen, so individual LazyColumns are each elements.

            2.) To get the production build, all you need to do is click on the release tab in the left edge of the screen in studio, then select release from the dropdown list instead of debug. 'Production' was substituted by me for 'release', but it's one and the same thing you see.

            As it states in this article, View Binding Tutorial for Android: Getting Started:

            Additionally, ButterKnife’s development is coming to an end. Jake Wharton, the creator of this library, is deprecating it in favour of View Binding.

            From the ButterKnife GitHub page:

            Attention: This tool is now deprecated. Please switch to view binding. Existing versions will continue to work, obviously, but only critical bug fixes for integration with AGP will be considered. Feature development and general bug fixes have stopped.

            How to model parent-child relationship in Android MVVM VMs?
            Asked 2020-Oct-23 at 14:06

            I'm working on an Android piano "quiz" app - users tap on the piano keys and then click the yellow "check" button to submit the answer for evaluation and see the correct answer drawn on the piano. The main QuizActivity has this layout:

            The upper part of the screen hosts a couple of controls (Text, submit buttons, etc.). The lower part of the screen is occupied by a custom PianoView component, that handles drawing of the piano keyboard.

            According to the MVVM principles, the PianoView should have its own PianoViewModel, that stores its state (i.e. currently pressed keys, highlighted keys, etc...) in a KeysStateRepository. The enclosing QuizActivity should also have a QuizActivityViewModel, that handles the various controls (submitting an answer, skipping a question...). The QuizActivityViewModel needs to be able to query the selected keys from the PianoView (or rather from its KeysStateRepository), submit them to the Domain layer for evaluation and then send the results back to the PianoView for visualization.

            In other words, the QuizActivity's ViewModel should own/be a parent of the PianoView's ViewModel to facilitate communication and data sharing.

            How can I model this parent-child relationship to communicate between the ViewModels?

            AFAIK a ViewModel cannot depend on another ViewModel (What would I pass as the ViewModelStoreOwner to obtain a ViewModel in another Viewmodel?). I don't think it's possible to achieve with Dagger-Hilt at least.

            Three solutions to work around this problem came to mind, all of them unusable:

            1 - The official way of sharing data between Views

            The Android dev docs recommend using a shared ViewModel to facilitate sharing of data between two Fragments / Views. However, this does not fit my use-case. The PianoView (or its ViewModel) should be the sole owner of its state with a Repository scoped to its ViewModel. Otherwise, the PianoView component would not be reusable. Consider for example another Activity, where I'd like to have two independent PianoView instances visible:

            Reusing a Shared ViewModel from the quiz activity would be obviously wrong, because it contains irrelevant methods and logic (i.e. submitting quiz answers) and would not fit the two-keyboard scenario.

            2 - Application-scoped repository

            A similar problem was tackled on Reddit with a proposed solution of using a shared instance of the repository. However, using a @Singleton KeyStateRepository would once again prevent the two independent keyboards to display different data.

            3(EDIT) - 2 duplicate repositories replicated by an Event Bus

            I could in theory create 2 independent ViewModels and 2 KeyStateRepository instances. The ViewModels would subscribe to an event bus. Each time a ViewModel invokes a mutable operation on its repository, it would also fire an event and the operation would get replicated via the other ViewModel subscribed to the same event bus.

            However, this feels like a fragile & complicated hack. I'd like to have a simple MVVM-compatible solution. I can't believe a simple parent-child relationship for two UI components is something unattainable in MVVM.

            ...

            ANSWER

            Answered 2020-Oct-14 at 06:43

            I would do the following, if you don't want to tie the PianoViewModel to your ActivityViewModel, I'd just create an interface, which the ActivityViewModel implements, and the PianoVM could have a nullable reference to that interface. This way neither the implementation, nor the existence of the component would be required for the PianoViewModel to work.

            How you get the ActivityViewModel is another question. Check out by activityViewModels() implementation for fragments, you probably can do the same with by viewModels() passing in the viewModelStore of the activity instead
