+## Ejemplo
+
+```bash
+# Solo instalar
+android_apk_install /home/lucas/builds/app-debug.apk
+
+# Instalar y lanzar con activity explícita
+android_apk_install /home/lucas/builds/app-debug.apk com.fnregistry.voiceguide .MainActivity
+
+# Instalar y lanzar sin activity (usa monkey LAUNCHER)
+android_apk_install /home/lucas/builds/app-debug.apk com.fnregistry.voiceguide
+
+# Llamada directa desde shell (no sourced)
+bash bash/functions/infra/android_apk_install.sh /path/to/app.apk com.example.app .MainActivity
+
+# Override ADB path
+ADB=/custom/path/adb.exe bash bash/functions/infra/android_apk_install.sh /path/to/app.apk
+```
+
+## Notas
+
+- Requiere WSL2 con `adb.exe` Windows accesible. El path por defecto es
+  `/mnt/c/Users/lucas/AppData/Local/Android/Sdk/platform-tools/adb.exe`.
+  Se puede sobreescribir con `ADB=...` o `ANDROID_SDK_WIN=<sdk_root>` antes
+  de invocar.
+- `wslpath` se usa para convertir el path WSL a formato Windows (`C:\...`).
+  Si no está disponible (entorno no-WSL), se usa el path tal cual.
+- La instalación usa `adb install -r` (reinstala si ya existe).
+- Si `package_name` se da sin `activity_name`, la app se lanza via
+  `adb shell monkey -p <pkg> -c android.intent.category.LAUNCHER 1`,
+  que es equivalente a pulsar el icono del launcher.
+- El script se puede sourcear (para usar la función en otros scripts) o
+  ejecutar directamente. Cuando se ejecuta directamente, delega en
+  `android_apk_install "$@"`.
