# Capability: android

Toolbelt Android operable desde WSL2. Cubre: ADB (`adb_wsl`, conexion al daemon Windows), AVD emulator management (list/start/stop/wait, geo-fix), APK lifecycle (`android_apk_install`, `android_app_clear`, `android_app_launch`, `android_uninstall`), Capacitor build pipelines (`capacitor_build_apk`, `deploy_capacitor_to_emulator`), logcat streaming. WSL2 -> Windows adb daemon, no requiere Android Studio.

## Ejemplo canonico

### Arrancar emulator + deploy Capacitor + logcat

```bash
./fn run android_emulator_list
./fn run android_emulator_start --avd Pixel_7_API_34 --wait

./fn run deploy_capacitor_to_emulator \
  --app-dir ~/projects/myapp \
  --avd Pixel_7_API_34 \
  --package com.example.myapp

./fn run adb_wsl -- logcat -v time | grep -E "(myapp|FATAL|AndroidRuntime)"
```

### APK install/uninstall manual

```bash
./fn run android_apk_install --apk ~/myapp.apk --device emulator-5554
./fn run android_app_launch --package com.example.myapp
./fn run android_app_clear --package com.example.myapp   # limpia datos sin uninstall
```

## Fronteras

- **NO compila APK desde Gradle nativo**. Solo Capacitor build. Para Gradle puro, ver issue 0076 (`gradle_run`).
- **NO instala Android SDK**. Asume `ANDROID_HOME` apuntando al SDK Windows accessible via WSL.
- **NO maneja iOS**. Solo Android. Para iOS, ver issue 0072h (gamedev roadmap).
- **NO depura nativo NDK**. Para LLDB-stage debugging, attach manual via Android Studio.
