Required LLM feature not found

[abaker]

Trying to run sample on two devices (Pixel 8 Android 15 with "Enable on-device GenAI Features" enabled, Pixel 9 Pro w/ GrapheneOS w/play services & AICore installed), and I get the following error:

Clicking "Run the demo" buttons results in a toast that "Model is unavailable yet and downloading in background"

[wilsoncastiblanco]

I got the same error, I think there are extra steps to install native libraries on the device since I saw this on the logcat
Unable to open libpenguin.so: dlopen failed: library "libpenguin.so" not found.

I'm running the demo on a Samsung Galaxy S24.

Note not sure if this is something that could cause the error (don't think so) but, the steps talk about verifying the release version:

Check out the AICore APK version in the Play store (under "about this app" tab) to confirm it starts with 0.thirdpartyeap

but, the beta version downloaded was 0.release.qc8650.prod_aicore_20240822.00_RC05.676804926

[MillionthOdin16]

I have the same error messages and issue as OP. I'm running the most recent Android 15 beta on Pixel 9 pro XL. I followed the specific instructions added to the readme as well, but no luck.

aicore version 0.thirdpartyeap.prod_aicore_20240822.00_RC05.676804926

Please ensure that you are only running the demo on Pixel 9 series device.

If you are seeing Required LLM feature not found error, please ensure that you have followed the instructions to set up your testing environment (Prerequisites & Update APKs sections especially).

[MillionthOdin16]

If you are seeing "Required LLM feature not found" error, please ensure that you have followed the instructions to set up your testing environment (Prerequisites & Update APKs sections especially).

I followed all the steps on my Pixel 9 and made sure that the apps are the correct version, but it's unable to download the model. I don't get any indication that there is any download progress at all.

Additionally, "0.thirdpartyeap.prod_aicore_20240822.00_RC05.676804926" appears to break all AI Core functionality for existing apps such as screenshots, phone call notes, and recorder summarization. Using the beta version of AI Core doesn't even allow the downloading of models for those tools. I had to unenroll in the beta and roll back to the normal release in order to successfully redownload the models after clearing the app data.

I'm wondering if there's an issue with downloading models on the EAP version?

For Pixel 9, try to uninstall the sample app then install the sample app again to see whether it could fix the download issue (maybe reboot as well).

For other functionalities not working in EAP version, we'll fix it in the next AICore release. Thanks for reporting the issue!

Yes, I've tried installing, rebooting, uninstalling and reinstalling, clearing app data for it and AI core, and as much as I can possibly think of.

I can't get to do anything other than give me an error message. The size of the EAP AI core data never exceeds 26 MB either.

They've stated it only supports the pixel 9 at the moment, so I don't think it will work.

Also confirming I see the same issue and stack trace as OP on a Pixel 9:

• I've followed all the steps on (https://developer.android.com/ai/gemini-nano/experimental), except for the line "that you are logged in with only the account that you intend to use for testing"; I have several accounts on my device. Perhaps this makes a difference?
• Android AI Core: 0.thirdpartyeap.prod_aicore_20240822.00_RC05.676804926
• Private Compute Service APK: 1.0.release.658389993

Same thing for the minimal example in the "Get started" page (https://developer.android.com/ai/gemini-nano/experimental#run-inference), I get the "Required LLM feature not found" error.

Can you please update this thread when you get a solution? I see the same stacktrace after following all steps except dẹleting all accounts except the enrolled one as well, but assumed I was stuck because I'm on a pixel 8. Apicore beta and PCS are the correct versions and enrollment is complete.

I also encountered this problem.

For people who are encountering this issue on Pixel 9 devices, are your devices rooted? AICore is not available on rooted devcies.

[MillionthOdin16]

For people who are encountering this issue on Pixel 9 devices, are your devices rooted? AICore is not available on rooted devcies.

I'm not rooted, running most recent version of Android 15 beta.

[enduringstack]

@bcdj if device is root，is there any methods using aicore?
