"""This module defines an AVD instance.

TODO(fdeng):
  The current implementation only initialize an object
  with IP and instance name. A complete implementation
  will include the following features.
  - Connect
  - Disconnect
  - HasApp
  - InstallApp
  - UninstallApp
  - GrantAppPermission
  Merge cloud/android/platform/devinfra/caci/framework/app_manager.py
  with this module and updated any callers.
