App 2.19.4: Export CarPlay data to the USB stick

Browse Source 
Read-only diagnostic for CarPlay's resolution: window, SurfaceFlinger
and display state captured while CarPlay is in front, display-related
properties without identifiers, Allgo's APK and libraries and
CarPlay-named system files, written to the app's folder on the stick.

upstream's EVABRPUploader text. The test emulator is now in the flake: `nix run .#car-emulator`

- 2026-10-23 — App 2.19.4: "Export CarPlay data" on the Logs tab (Foreground apps card), for the
question whether CarPlay's resolution can change. CarPlay with policy_control still leaves a grey
strip, also after reconnecting: Allgo announces a smaller picture to the iPhone. 20 s after the
press (time to open CarPlay) it writes to `<stick>/Android/data/<package>/files/
nilsmg4-carplay-<time>/` — the only place on a removable volume Android 9 lets an app write:
`dumpsys window windows`, `SurfaceFlinger`, `display`, `activity activities`, `wm size/density`,
the display-related system properties (identifiers filtered out), Allgo's APK and native
libraries, and CarPlay/Allgo/iAP2-named files under /system, /vendor, /odm, /product. It reads
the car and writes only to the stick. Owner's choice to export Allgo's software for analysis

errors. XDA (leonkernan, page 30) found SAIC's SystemUI hides its top bar itself for a whitelist
that includes com.allgo.carplay.service — compiled into SystemUI, not changeable from the app.

car ended in an installer message about a broken package, while the same APK installed through
the Bluetooth-settings route; the message was only a toast and logcat, so its exact words are
