… 15) Fixed a critical ANR / Crash cycle occurring on Android 15 when the app is running within a Work Profile. The crash was caused by a SQLiteConstraintException in the ProxyApplicationMapping table. During profile refreshes or package updates, Android 15 sometimes reassigns UIDs in a way that creates collisions with existing database entries. The previous tombstoneApp implementation performed a blind update, which triggered a unique constraint violation and corrupted the database state.

Pull request overview
Fixes a crash/ANR loop caused by SQLiteConstraintException when updating ProxyApplicationMapping UIDs (notably in Android 15 Work Profiles), by replacing a single SQL update with a transactional sequence intended to avoid unique/primary-key collisions.
Changes:
- Converts
tombstoneApp(oldUid, newUid)from a singleUPDATEquery into a@Transactionmethod that deletes conflicting rows before updating UIDs. - Adds DAO helpers to delete by UID and to update UID using
UPDATE OR IGNOREas an extra safety measure.
