The player has a launcher (category.HOME) + a boot receiver, but auto-start was
unreliable where you can't set a home launcher (Android TV) and on Android 14+,
where USE_FULL_SCREEN_INTENT is auto-revoked for non-calling apps so the boot
full-screen launcher silently no-ops.
Boot launch:
- BootReceiver now does a direct background startActivity when 'display over other
apps' (SYSTEM_ALERT_WINDOW) is granted — a real exception to the bg-activity-launch
restriction, and the one path that works on Android TV. Full-screen-intent
notification kept as a fallback (locked screen / no overlay).
- Boot notification moved to a dedicated HIGH-importance channel (full-screen
intents are only honored from one), and it auto-dismisses once the UI is up.
Setup screen — new permission rows so operators can grant what boot-launch needs:
- Launch on Boot (USE_FULL_SCREEN_INTENT, shown on Android 14+)
- Background Activity (battery-optimization exemption)
- Display Over Apps (SYSTEM_ALERT_WINDOW)
Made the screen scrollable and ~50% smaller text/buttons so all rows + Continue
fit on one screen (incl. landscape signage). Install-Unknown-Apps subtitle now
states updates are signature-verified, so it doesn't read as 'install anything'.
Verified end-to-end on an Android 16 emulator: after reboot the app auto-launched
(Direct launch via overlay) and the boot notice cleared itself; all rows toggle.
