Description: Welcome to the live Q&A for the Architecture series on MAD Skills, hosted by Android Developer Relations Engineer Manuel Vivo. This time, Manuel is joined by Yigit Boyar, TJ Dahunsi, and Miłosz Moczkowski. 0:00 - Intro 1:10 - Is LiveData deprecated? 2:10 - What is business logic? What is the motivation behind moving business logic down to the data layer? 3:27 - How to access resources like strings, colors in the viewmodel as we should not link the context to it? 4:48 - How do I make a service and composable/viewmodel communicate to each other? 5:45 - What are the best practices now to allow a smooth future transition to KMM/KMP? 7:25 - What is VM in MVVM, since ViewModel is just a state holder? What classes does it actually map to? 9:10 - ​Regarding Architecture, are there any updates /recommendations related to multi-modules projects(by layers)? Like the architecture samples. 10:00 - Should we use Flow in data sources? Repositories? Interactors/use cases? 11:17 - When to use use cases? 13:00 - ​Passing cascading suspend in repository is anti pattern in Android mvvm with flow? 14:25 - ​What is the recommend pattern for a ViewModel to tell the UI navigate to a different Fragment/Screen? 18:40 - ​How to define conditional navigation graph based on user configuration? 20:25 - Where should we put work manager and services in MVVM / Clean architecture? 23:47 - Why use ioDispatcher in repository to access database sometimes, and sometimes not? 26:15 - ​What is the advised way to transport complex data from one screen to the other when we are dealing with memory sensitive data? 29:40 - ​MVVM or MVI for Compose? 31:22 - As projects expand, should I move domain/data layers to separate modules? 33:00 - ​How should the view hierarchy be maintained to ensure an efficient app? Should view hierarchy be as shallow as possible? 36:52 - What is the best way for returning error from other layer to the presentation layer? 38:50 - Which layer should I put domain models and mappers that map from Api/Db models? 41:07 - ​Does the UI layer → Domain layer → Data Layer pattern work for non-mobile app Android surfaces i.e. App Widgets, Quick Settings tiles, Notifications, Android Auto, Wear tiles etc? 41:12 - Multiple activities or Single activity multiple fragments? 45:15 - Outro Catch more videos on Architecture → goo.gle/Architecture Watch more MAD Skills episodes → goo.gle/madskills Subscribe to Android Developers → goo.gle/AndroidDevs #Featured #Latest #MADSkills product: Android - General;
