Fixing the Google Assistant on My Android Work Profile

Launching the Google Assistant in the Android work profile

One of the products I develop for at work is a digital assistant for food service operations. Our voice component of the digital assistant is deployed to Google Assistant compatible devices through Actions on Google. To aid in my work I use a personal Android device to test our product.

In the last few months I have run into conflicts using the Google Assistant on my device’s work profile. For the uninitiated, the Android work profile is a separate space on the device dedicated to walling off the areas between personal apps and work apps. Since my work developer account is tied to the company organization, it encourages me to use a work profile when using the account on my device.

Problematic Assistant

The problem is that while using the work profile, the Default digital assistant app can’t be set. Worse, the Voice input can’t be changed back to Google if accidentally switched away since it’s “un-selectable”.

If the Voice input isn’t set to Google in the screenshot above, the work profile will fail to launch the Google Assistant.

Even worse, if the user tries to tap on Default digital assistant app to switch it from None, the screen will quickly navigate the user to Controller and immediately return.

My theory is that there is a permission that can’t be prompted to the user under the work profile causing it to crash.

Secondary Bug

On a side note, sometimes while using the work profile the user will be shown The Google App isn't your default Assist App. on certain screens. I believe this bug can be resolved by disconnecting the Google app between the work profile and personal profile as shown below. This can be found under the Advanced settings section of the work profile Google app info page.

Luckily, there’s a solution to launching the Google Assistant in the work profile. We do this by manually changing the secure settings on our device’s work profile to use Google as the Voice input for the digital assistant.

Requirements (that I know of?):

It probably doesn’t hurt to keep the assistant the same between the personal and work profiles to reduce complications between the two spaces. But it’s not clear if that’s a requirement going forward.


Before we get started, I later learned how to fix this using only adb by issuing the following two commands. One sets the default assistant setting, and the other seting the voice interaction service to use the Google Assistant. It’s set to run under user 10, which is my work profile.

➜  ~ adb shell settings put --user 10 secure assistant
➜  ~ adb shell settings put --user 10 secure voice_interaction_service
  1. First we find out the user id of the work profile. Here I can see that it’s 10.

     ➜  ~ adb shell pm list users
       UserInfo{0:Kyle:c13} running
       UserInfo{10:Work profile:1030} running
  2. Next grab the value for the voice_interaction_service from the personal profile. I included this step in the event Google changes the value in the future.

     ➜  ~ adb shell settings get --user 0 secure voice_interaction_service


    If I try to grab the voice_interaction_service value from my work profile, I can’t see anything because shell access is forbidden.

     ➜  ~ adb shell settings get --user 10 secure voice_interaction_service
     Exception occurred while executing 'get':
     java.lang.SecurityException: Shell does not have permission to access user 10

    Now that we have the value for voice_interaction_service, we need to write it back to our work profile.

    Since the work profile on my device restricts sideloading APKs and shell access, I need an app that can edit the Settings Database on my behalf. I chose SetEdit.

    Make sure you install the app to your device using your work profile or you won’t be able to change the correct setting.

  3. Grant WRITE_SECURE_SETTINGS permissions to the app.

      ➜  ~ adb shell pm grant --user 10 by4a.setedit22 android.permission.WRITE_SECURE_SETTINGS
  4. Open up the SetEdit app on the device.

  5. Under the Secure Table, find the voice_interaction_service key and update the value grabbed by the personal profile earlier. In my case it is:

    Updating the voice_interaction_service value with SetEditUpdating the voice_interaction_service with SetEdit

  6. Under the Secure Table, find (or create) the assistant key and update the value to:
  7. The result should be instantaneous. Go ahead and open up the Google Assistant app in the work profile via its app icon. It should now load!

The work profile on Android is a neat idea. Separating the user spaces to keep data apart is a cool concept to protect a user’s privacy. However, sometimes the system level apps have trouble in this separate space. Especially when they rely on API/Screen calls that aren’t quite available.

I hope Google resolves this issue in the future as it’s a very annoying bug. Until then, this should serve as a guide to help other users fix their Google Assistant in the work profile.
