Android 9 (API 28): android.os.ServiceSpecificException: (code 7) gets logged

[mreichelt]

When running the sample code on an emulator running Android 9.0 Pie (API 28) and clicking on 'create' and 'sign', the app will log an exception - though it will continue to run fine.

The exception:

The culprit seems to be this code (also exists in verifyData method):

This is still happening on Android Q, beta 2.

This issue has been fixed in Beta 4/final SDK release of Android 10: https://issuetracker.google.com/issues/74355119

Can be closed IMHO

It's still an issue on the latest Android 10 update, but nice to see the fix is scheduled to come in "a future version".
