Hello,

Without debugging the app for you, I would recommend that you read through
the sample code and watch out for all TODO comments, and also go over
https://developer.android.com/training/safetynet/attestation thoroughly.

We have recently made changes and also had an independent team test the
sample code, so it should work as long you make the correct TODO changes
and follow the updated docs.

Hey there, what happend that the safetynet sample is again unuseable
because of such network error?
After release of 16.0.0 version neither 15.0.1 or 16.0.0 is not working
(network error), i tried new api key but still receiving the same error,
who else has the same problem?

Hello,

Please read the section on Error cases (
https://developer.android.com/training/safetynet/attestation#compat-check-response
):

Error cases

The JWS message can also show several types of error conditions:

- A null result indicates that the call to the service didn't complete
successfully.
-

An error parameter indicates that an issue occurred, such as a network
error or an error that an attacker feigned. Most errors are transient and
should be absent if you retry the call to the service. You may want to
retry a few more times with increasing delays between each retry.

*Important:* If you trigger more than 5 calls per minute, you exceed the
API's fixed rate limit, which causes the remaining requests during that
minute to return an error.

If an error occurs, the result cannot represent a passed test, as an
attacker might intentionally trigger such an error.

Well, so for production application they will have to ask for higher
quotation than 5 calls per minute, the temporary error was also assigned to
the mention device altough on other devices was api key already working,
the temporary error was also seen after creating new project and new api
key for this device..
