Chromecast HD on Android 14: current_app is always None (Google TV command greps mResumedActivity, renamed to topResumedActivity)

[lazi3b0y]

Summary

On a Chromecast HD running Android 14, AndroidTVSync.update() / current_app() always return None for the current app, so Home Assistant's media_player entity for the device never gets app_id, app_name or source.

The cause is in BaseTV._cmd_current_app(): the device matches the "Google Chromecast" special case (manufacturer contains "Google", model contains "Chromecast"), which selects CMD_CURRENT_APP_GOOGLE_TV. That command is dumpsys activity a . | grep mResumedActivity, and Android 14 renamed that line to topResumedActivity, so the grep matches nothing. The special case is checked before the Android 13/14 branch, so the generic CMD_CURRENT_APP13 (which works on this device) is never reached.

PR #368 ("Only use GOOGLE_TV constants for Android <14") fixes exactly this and has been open since 2025-11-30 without review. The corresponding Home Assistant report (home-assistant/core#153778) was closed as stale in 2026-02 without a fix. I am filing this so there is an issue to track it; happy to test a build.

Environment

• androidtv 0.0.75 (the version pinned by Home Assistant), Python 3.14, adb_shell transport over TCP port 5555
• Device: Google Chromecast HD, product_id boreal, Android 14, security patch 2025-10-01
• device_properties: {'manufacturer': 'Google', 'model': 'Chromecast HD', 'sw_version': '14', 'product_id': 'boreal', ...}

Reproduction

With Moonlight (com.limelight) in the foreground:

import os
from androidtv import setup, constants as c

atv = setup("192.168.86.111", 5555, adbkey=os.path.expanduser("~/.android/adbkey"), device_class="androidtv")
print(atv.update())        # ('idle', None, [...running apps...], ...)
print(atv.current_app())   # None

for name in ("CMD_CURRENT_APP", "CMD_CURRENT_APP13", "CMD_CURRENT_APP_GOOGLE_TV"):
    print(name, repr(atv._adb.shell(getattr(c, name))))

Output:

CMD_CURRENT_APP            ''
CMD_CURRENT_APP13          'com.limelight\n'
CMD_CURRENT_APP_GOOGLE_TV  ''

Why the Google TV command is empty on this build:

dumpsys activity a . | grep mResumedActivity      -> (nothing)
dumpsys activity a . | grep topResumedActivity    -> topResumedActivity=ActivityRecord{... u0 com.limelight/.Game t13119}
dumpsys window windows | grep mCurrentFocus       -> (nothing)

The same applies to _cmd_current_app_media_session_state(), which selects CMD_CURRENT_APP_MEDIA_SESSION_STATE_GOOGLE_TV for the same reason (..._STATE13 returns the app correctly).

Possible fixes

• Merge Only use GOOGLE_TV constants for Android <14 #368 (skip the Chromecast special case when sw_version >= 14), or
• make CMD_DEFINE_CURRENT_APP_VARIABLE_GOOGLE_TV grep for both spellings: grep -E 'mResumedActivity|topResumedActivity', which keeps the Chromecast path working on older and newer builds.
