How Shizuku is used

Can replace the system At a Glance feed and power widgets, shortcuts, predictions and device triggers via `cmd smartspace` and system services through Shizuku.

This is an AI-assisted analysis of Shizuku-related usages in the app's public source code. It is best effort, so it may not catch every single usage.

How this app uses Shizuku

Smartspacer uses Shizuku to run an elevated service that unlocks its enhanced widget mode and system integrations.

Replace At a Glance feed: sets its own service as the temporary system Smartspace provider and restores the default on reset, restarting launchers or System UI so the change applies.
Read system Smartspace targets: binds directly to the system Smartspace service to create sessions and receive targets for home and lock surfaces.
Suggest apps and widgets: creates system app prediction sessions for the home surface and widget surface to show predicted apps and predicted widgets.
Show and launch shortcuts: loads installed app shortcuts with icons for the expanded view and launches the chosen shortcut on tap.
Toggle flashlight: switches the camera torch on or off from a widget tap or receiver.
Enable Bluetooth on demand: turns Bluetooth on when a Bluetooth requirement needs it.
List saved WiFi networks: reads saved WiFi configurations to let users pick networks for WiFi based requirements.
Open notification targets: resolves a notification content intent to its underlying intent so tapping opens the right screen.
Load restricted content: proxies content provider type, stream type and file access through the elevated service for widget content.
Track foreground and recent apps: observes foreground processes and recent task packages to drive app and task based requirements.
Watch crashes and restarts: monitors app deaths and Assistant intelligence stops to notify and reconnect the native mode.
Grant restricted settings: allows restricted settings access for the app and permits background activity starts around shortcut launches.
Personalize greeting: reads the device username to use as the default greeting name.

Notable details

Enhanced mode requires the elevated service to stay running; if the system service stops, the app prompts to reconnect. Flashlight has a normal activity fallback when the elevated service is unavailable.
