Debugging Your Android App: Common Errors, State Management and Concurrency

Welcome to the world of Android development with Jetpack Compose! Building modern UIs with Kotlin’s declarative approach is incredibly powerful, but like any development paradigm, it comes with its own set of potential errors and patterns to master. This article will guide you through common errors you might encounter in your Compose app, introduce essential debugging tools, and delve into managing UI state effectively with LiveData and StateFlow, as well as handling concurrency with Kotlin Coroutines and Flows.
