Windows: Android tools report platform-tools not found despite working adb

## Summary On Windows, Argent cannot detect Android platform-tools/ADB even when `adb` is installed and working, causing Android tools (`list-devices`, `boot-device`, `launch-app`) to fail. ## Environment - OS: Windows (VS Code workspace) - Argent version: `0.8.0` - Flutter app project (Android emulator in use) - Running emulator: `emulator-5554` (AVD `Medium_Phone`) - Android SDK path: `C:\Users\raouf\AppData\Local\Android\Sdk` - `adb` path: `C:\Users\raouf\AppData\Local\Android\Sdk\platform-tools\adb.exe` ## What works - `adb devices -l` returns the running emulator. - `flutter devices` returns `emulator-5554`. ## What fails ### 1) Argent device discovery ```bash argent run list-devices ``` Result: ```json { "devices": [], "avds": [] } ``` ### 2) Argent boot-device (Android) ```bash argent run boot-device --avdName Medium_Phone ``` Result: ``` Android SDK Platform Tools not found. Install with `brew install --cask android-platform-tools` or via Android Studio → SDK Manager. If installed, ensure `adb` is on PATH or set `$ANDROID_HOME` to the SDK root (the resolver checks `$ANDROID_HOME/platform-tools/adb`). Only required for Android devices and emulators. Assertion failed: !(handle->flags & UV_HANDLE_CLOSING), file src\win\async.c, line 76 ``` ### 3) Argent launch-app (Android) Invoked via MCP `launch-app` with: - `udid: emulator-5554` - bundle id test target (e.g. `com.android.settings`) Result: same **Android SDK Platform Tools not found** error. ## Repro steps 1. Start Android emulator (e.g. AVD `Medium_Phone`) so `adb devices` shows `emulator-5554`. 2. Confirm `adb` exists at `%ANDROID_HOME%\platform-tools\adb.exe`. 3. Run `argent run list-devices`. 4. Run `argent run boot-device --avdName Medium_Phone`. ## Expected behavior - Argent should detect Android devices/AVDs when `adb` is available and emulator is running. - `list-devices` should include Android entries. - `boot-device` should attach/boot successfully without platform-tools error. ## Actual behavior - Android is treated as unavailable (`devices: []`, `avds: []`). - Android actions fail with "Platform Tools not found" despite valid SDK + working `adb`. ## Additional notes - Set env vars and restarted VS Code: - `ANDROID_HOME=C:\Users\raouf\AppData\Local\Android\Sdk` - `ANDROID_SDK_ROOT=C:\Users\raouf\AppData\Local\Android\Sdk` - Also tested injecting env + PATH inline before Argent command; behavior unchanged. Potentially this is a Windows-specific environment/path resolution issue in Argent's Android tooling process.
