Compose Beyond UI — Declaratively Orchestrating Melodies
summary
The talk explains how Jetpack Compose’s low-level Runtime (the module beneath the UI layer) provides declarative execution primitives that can be used beyond building UIs. It shows Runtime APIs and usage examples, then demonstrates a novel application—"declarative audio processing"—that plays melodies and sound effects described in code, illustrating how Compose’s declarative paradigm can be applied to custom, non-UI processing.
