summary
Shows a working integration of an EPUB viewer into Jetpack Compose using Esky EPUB SDK and AndroidView in Compose, with a concrete app that supports paging, a seek bar, table of contents and font-size changes. Explains avoiding unnecessary recompositions by moving heavy init to the factory, short updates in update, and using rememberSaveable/state holder plus ViewModel for single source of truth. Gives actionable sync flows (SDK index → state holder → composables and reverse), and performance tips like skipping activity recreation and preopening books to avoid costly analysis.
