Handle KeyStoreException in Android 8.0 #31

Open damirarh opened 6 years ago

damirarh commented 6 years ago

This exception is thrown in "verify" on Android 8.0 if new fingerprints were enrolled after "save" has been called. On Android 8.1 KeyPermanentlyInvalidatedException is thrown in the same scenario (but already in "has"), therefore I'm handling it the same - i.e. deleting the key so that it will be recreated on next call.

When the application receives this error (KeyPermanentlyInvalidatedException), it should reinitialize the fingerprint usage - the user will have to reenter the password and agree to store it using the fingerprint.

@SleimanB Did you check what was the cause in the thrown exception using the code I added to extract it? Is it the same exception/message as I am checking for in my code, i.e. Key user not authenticated?
