deploy-voltius-to-phone

Apps & Automation

Use when the user wants a working Voltius Android build installed on their own physical phone to test/poke at by hand (not MCP-driven automation) — builds the aarch64 debug APK and installs + launches it on the connected phone, then hands off for manual testing.

Deploy Voltius to my phone (manual testing)

Overview

Goal: get the current code running on the user's real phone so they can use it themselves. This is the hand-off flow, not the automation flow — no MCP, no CDP. Just: build the APK, make sure adb can see the phone, install + launch, tell the user it's ready.

For driving the app yourself via screenshots/clicks, use iterating-on-voltius-android instead. For no-phone iteration, use iterating-on-voltius-android-emulator.

1. Build the APK (aarch64 — real phones are arm64)

scripts/android-build.sh aarch64

Output: src-tauri/gen/android/app/build/outputs/apk/universal/debug/app-universal-debug.apk (~310 MB, debug-signed with the committed keystore/voltius-debug.keystore, so adb install -r upgrades in place without uninstalling). Build on the x86_64 WSL2 laptop — the NDK runs native there; on an aarch64 host it runs under QEMU (~1h). Do NOT regenerate the keystore (breaks -r upgrades).

2. Make sure adb sees the phone (do this BEFORE installing)

Phone plugs into Windows; WSL reaches it through a Windows-hosted adb server. Set the socket inline on every Bash call (each call is a fresh shell). Full setup + the three blockers (Hyper-V firewall, adb version match, RSA auth prompt) are in the android-adb-wsl-setup memory.

export ADB_SERVER_SOCKET=tcp:192.168.240.1:5037
timeout 3 bash -c 'echo > /dev/tcp/192.168.240.1/5037' && echo OPEN || echo "DROPPED — firewall"
adb devices    # want: <serial>  device   (not "unauthorized" → tap "Allow" on phone; not empty → check cable/firewall)

3. Install + launch

ADB_SERVER_SOCKET=tcp:192.168.240.1:5037 \
  scripts/android-deploy.sh src-tauri/gen/android/app/build/outputs/apk/universal/debug/app-universal-debug.apk

This runs adb install -r then am start -n com.voltius.app/.MainActivity. On success it prints the WebView debug socket line — that confirms the app actually came up, not just installed.

4. Hand off

Tell the user it's installed and launched on their phone (app name Voltius), and that they can reopen it from the launcher. If you changed something specific, tell them what to look for. If they report a crash, you can pull it: ADB_SERVER_SOCKET=… adb logcat -b crash -d (Rust panics show under RustStdoutStderr).

Common mistakes

Mistake	Fix
Building `x86_64` for a real phone	Real phones are arm64 — build `aarch64`
Forgetting `ADB_SERVER_SOCKET`	Set it inline every Bash call — fresh shell each time
`adb devices` shows `unauthorized`	Unlock phone, tap "Allow USB debugging" (RSA prompt)
`adb devices` hangs	Bounded `timeout 3 bash -c 'echo >/dev/tcp/<ip>/5037'` first; hang = Hyper-V firewall drop
Regenerating the debug keystore	Breaks `install -r` upgrades — it's committed, never regenerate
"It installed" = it works	Installed ≠ launched. Check the deploy script's WebView-socket line, or ask the user
