Invalid JWS

[phileo]

in the SafetyNetApi.AttestationResponse.getJWSResult() jws string, it is supposed to contain 2 periods according to the JWS spec. However, when I run the sample app, I only see one single period. On the server side, this causes an IllegalArgumentException with OfflineVerify::JsonWebSignature.parser.parse()

Any ideas as to why the generated JWS string does not contain 2 periods?

For me it worked only after installing the apk on real device, instead of emulator. On emulator it was showing invalid JWS without any period.

I've found out the problem! The problem results in the logger which only log 4024 characters The real value could not be parsed by the logger Debug and inspect the element to get the real value
