Google Home API PermissionsManager HomeClient problem

emrcelebi — Tue, 25 Nov 2025 21:14:16 GMT

Hello all,

I am testing Home API to create my routines. I clone sample app and start to work on it.

I tested android app with two devices and one of them is working and other one is not working.

- Pixel 7 Pro. Successfull

- Lenovo Tab M7 (TB-7306F). Failed.

I was working on using my old Lenovo tablet as home control device however those app not working on it.

Tablet is using Android GO edition and it has lack of some core functionalities.

Sample app is failing with below error code:

Explain: Failed to get user selected account for home access. com.google.home.HomeException: 13: Task failed with error: 17

As I understand from my debug, it is trying to use HomeClient.registerActivityResultCallerForPermissions function in PermissionsManager.kt init function. However, Android GO edition doesn't have accounts selection functionality, it is failing automatically for authentication.

Is there any other way to get permissions without using this class?

Thanks 🙂

The Google Home Permissions API is designed to use the standard Android Activity Result API (which replaces startActivityForResult) to launch a dedicated Google Play Services screen.

HomeClient.registerActivityResultCallerForPermissions is called.
The system attempts to launch the Google Account picker/consent screen.
On Android Go, the Google Play Services package (GMSCore), which your Home API code relies on for authorization, is modularized and stripped down. Hence, the task fails immediately, resulting in the Task failed with error: 17 (which is often API_UNAVAILABLE or related to a missing component).

Since the Home API's authorization flow is tightly integrated with a Google Account picker, your only practical solution is to target a non-Go edition device.

For your use case as a dedicated home control panel, here are a few options:

Use the Pixel 7 Pro (or similar) as the control device. This works because it has the full GMSCore suite.
Use a different tablet that runs the full standard version of Android (even an older/budget one, as long as it's not a Go Edition).

Hi @arm_dpe , thanks for clarification. I understand that I can't use my old tablet for testing and reusing :). I will check other options.
