# The DEV flavour (ANDROID.md → "Iterating without cargo"): the detour build
# WITHOUT tauri's custom-protocol feature, so the library embeds the dev URL
# (http://localhost:1421) instead of dist/. On the phone, `adb reverse` makes
# the phone's localhost:1421 THIS machine's Vite dev server over the USB
# cable — no LAN address, no firewall hole, hot reload — and cargo runs only
# when Rust changes. Both flavours share target/: switching flavours
# recompiles tauri and the app crate once (~3 min), the leaf crates stay
# fresh — cheaper than a second 15 GB cache on this drive.

#   bash src-tauri/android/dev.sh            # build (when Rust changed) + install + tunnel + launch
#   bash src-tauri/android/dev.sh --no-build # reinstall the last dev library, re-tunnel, launch
#   bash src-tauri/android/dev.sh --build-only # just the library (the phone is busy or absent)
#   bash src-tauri/android/deploy.sh         # the embedded build again (what the phone keeps)
#
# Then start the "frontend" dev server (npm run dev / the Browser pane's
# "frontend" launch config). The phone needs it running — and the cable.
