Demo App: crash after requesting fingerprints.list() #14

Closed ijdoc closed 11 years ago

ijdoc commented 11 years ago

Activity ran properly but crashed after pressing the fingerprints.list() button. No other button was pressed before expect the Menu > Settings, which did not seem to do anything.

Trace:

@elyas-bhy seems to be related to the fact that the cloud service may have returned an empty list to start with since subsequent calls after requesting a URN do not crash the app.

Feel free to close this issue in favour of a more accurately described one.
