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

Shizuku is used to start a privileged helper that lets the phone project its apps to a car headunit like Android Auto.

• Show projection display: creates a dedicated virtual display for the car screen so phone content can be rendered for the headunit and resized or reattached when the video output changes.
• Open phone apps on car: launches the phone app the user picks onto the car display, including the main projection UI and individual embedded apps, so they appear on the headunit.
• Control apps from car: sends touch, button and back actions received from the car to the app shown on the car display, so the headunit controls the phone app.
• Hear media and calls: captures phone media output and phone call downlink audio for streaming to the headunit, so music and calls play through the car.

Notable details

If the privileged helper cannot create its display, the app falls back to a local virtual display with reduced behavior (new app screens may appear on the phone instead of staying on the car display).
