Is there a way to use Firebase App Check For Huawei Devices or an alternative/combo?

Question

I have created a mobile app in flutter and have enabled Firebase App Check for both Android (Google Play) and iOS (App Store Connect). However, I have been researching the steps necessary to publish the app on App Gallery as well(Huawei). From previous experience I know that the same app bundle is perfectly acceptable by app gallery as well (very simple app - no firebase or other cloud services). However, in this case I have been researching how to extend the app check functionality to include Huawei Devices and cannot seem to find any relevant information. From what I gather from the firebase docs, one solution would to implement a custom Android client implementation AND a custom server implementation which seems a bit overkill and also poses other problems (server multi region availability etc).

Does anyone know if there is a better solution/alternative? The ultimate goal is to have firebase app check enabled for Google Play and iOS and something similar ( or a way to use firebase app check ) to authenticate requests from huawei devices.

I tried searching for information on how one can integrate firebase app check with huawei devices. I was expecting this to be a common problem and to find relevant information and implementations. However, I could not find any information or proposed solutions.

Answer 1

There is nothing built into Firebase App Check to attest apps on Huawei devices, and I don't immediately see any promising search results for it either.

However it should be possible to roll your own.

1. First, you'll want to research how to attest apps on Huawei devices, which (from my quick search) seems to be done through its Safety Detect APIs.
2. Then, once you've attested the app's authenticity, you'll need to implement a custom App Check provider to pass the information on to Firebase.

Once you implement it, I'm quite sure others would love to use it to - so please do share any positive results you get.
