Jetpack Compose has revolutionized Android development, providing a declarative approach to building UI. However, managing side effects — operations that impact states outside the composable scope — is crucial for smooth and efficient application behavior. In this blog, we’ll explore Jetpack Compose’s side-effect APIs and demonstrate their practical usage with examples. By the end, you’ll have a strong grasp of how to handle lifecycle events, network calls, state updates, and more effectively.
In Jetpack Compose, side effects refer to tasks or operations performed outside the composable functions, such as:
- Toast messages
- Logging
- One-time API calls
- Observing lifecycle changes
Compose provides several tools to manage side effects:
- LaunchedEffect
- DisposableEffect
- SideEffect
- ProduceState
- rememberUpdatedState
Let’s dive into each one with examples to understand their behavior and use cases.
