How Shizuku is used

Can run custom shell commands, toggle Wi-Fi, Bluetooth, mobile data, airplane mode and force stop apps via `svc`, `am` and `settings` shell commands.

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

Latch uses Shizuku to run elevated shell actions from local automation rules. Each bullet below is triggered by the user's own if/then rules:

Run custom shell commands: text the user types as a shell action in a rule is executed with elevated shell privilege through Shizuku.
Toggle Wi-Fi connections: a rule action turns Wi-Fi on or off with the svc wifi enable and svc wifi disable shell commands through Shizuku.
Toggle Bluetooth connections: a rule action turns Bluetooth on or off with the svc bluetooth enable and svc bluetooth disable shell commands through Shizuku.
Toggle mobile data: a rule action turns mobile data on or off with the svc data enable and svc data disable shell commands through Shizuku.
Toggle airplane mode: a rule action turns airplane mode on or off with the settings put global command plus an airplane mode broadcast through Shizuku.
Force stop apps: a package name chosen in a rule action is stopped with the am force-stop shell command through Shizuku.
