Managing Data Restoration with the Architecture Components
summary
How Le Bon Coin uses AndroidX SavedState for ViewModel inside Architecture Components to make UI state survive process death, demonstrating a fragment that restores after the process is killed and contrasting volatile ViewModel state with disk persistence. Practical techniques covered include the saved-state module, testing process-death recovery with adb or activity kills, and generating ViewModel factories with assisted injection to reduce boilerplate, with the concrete limit of about 1 MB per saved-state Bundle.
