Nvidia shield (androidtv) play/paused status problem

Sorry to dig up an old thread, but I ran into this today, and figured I might as well post my configuration in case somebody will need it in the future. This is for Shield Pro:

media_player:
  - platform: androidtv
    name: Home Theater
    scan_interval: 1
    host: 192.168.1.156
    exclude_unnamed_apps: true
    state_detection_rules:
      "org.xbmc.kodi":
        - "playing":
            "media_session_state": 2
            "wake_lock_size": 2
        - "paused":
            "media_session_state": 2
            "wake_lock_size": 1
        - "standby":
            "media_session_state": 1
            "wake_lock_size": 1
      "com.netflix.ninja":
        - "media_session_state"
      "com.amazon.amazonvideo.livingroom":
        - "playing":
            "media_session_state": 3
            "wake_lock_size": 3
        - "paused":
            "media_session_state": 2
            "wake_lock_size": 1
        - "standby":
            "media_session_state": 0
            "wake_lock_size": 1
      "com.disney.disneyplus":
        - "playing":
            "media_session_state": 3
            "wake_lock_size": 3
        - "paused":
            "media_session_state": 2
            "wake_lock_size": 1
        - "standby":
            "wake_lock_size": 0

It works well enough to turn on/off lights when you pause and resume playing in any of the apps above. There are some quirks, like, for example, fast forwarding in amazon prime videos app is considered a “pause”, but it otherwise it works well.
Oh, and Disney+ initial state actually reports media_session_state as null, which is not supported by HomeAssistant configuration, since it expects an integer.

Sorry to dig this up again, but the androidtv media player doesn’t work properly for me on my shield with plex.

If I run this to get the status of the shield:

service: androidtv.adb_command
data:
  entity_id: media_player.nvidia_shield
  command: GET_PROPERTIES

I get the following in the media_player attributes:

adb_response: >-
  {'screen_on': True, 'awake': True, 'audio_state': 'paused', 'wake_lock_size':
  2, 'current_app': None, 'media_session_state': None, 'audio_output_device':
  None, 'is_volume_muted': None, 'volume': None, 'running_apps': None,
  'hdmi_input': None}

As you can see, it says that the shield isn’t running any app, despite it actively playing a video in plex.

Is anyone else seeing this? Thanks
