To resume install sessions across device boots, persist session details and read at boot. Drop sessions older than 3 days, since they're probably buggy installers. Add session callback lifecycle around open/close to give home apps details about active installs. Also give them a well-known intent to show session details. Extend Session to list staged APKs and open them read-only, giving installers a mechanism to verify delivered bits, for example using MessageDigest, before committing. Switch to generating random session IDs instead of sequential. Defensively resize app icons if too large. Reject runaway installers when they have too many active sessions.
