Android Keystore Error “could not generate key in keystore”

While I don't know the full answer, I can help continue your search. The binder implementation on the other side of mBinder is the native keystore. If I recall fully, it's behavior is to either 1) support key operations at a software level, or 2) delegate to a OEM-provided keymaster library that (presumably) interfaces to the OEM's hardware-backed keystore. More info on this here, here, and here.
