App Lifecycle
Instructions
Mobile apps run in a hostile runtime. The OS freezes, backgrounds, and kills processes to preserve battery and memory. Treating the lifecycle as an afterthought leads to lost data, broken deep links, and angry reviews.
1. The Lifecycle States
Both platforms converge to roughly:
| State | iOS term | Android term | Cross-platform term |
|---|---|---|---|
| Visible & interactive | Active | Resumed | Foreground |
| Visible but not active | Inactive (incoming call, control center) | Paused | Inactive |
| Not visible | Background | Stopped | Background |
| Frozen but in memory | Suspended | Stopped | Suspended |
| Gone | Terminated | Process death | Killed |
