Is Your App Ready for Foldable Phones?
summary
Foldable phones use a 4.58" cover and a 7.3" main display with ~420 DPI, support three multi-window multitasking, and treat unfolding as a configuration change so apps must preserve state (onsaveinstancestate or Android ViewModel) or handle config changes manually. Android adds an opt-in multi-resume lifecycle (one manifest flag) and promises foldable/multi-display APIs plus an emulator APK and developer guides delivered via Samsung/Android sites in Q4. Developers should test resizing, continuity, and multiple resumed activities.
