/Users/tom/.jenkins/jobs/CalabashExamples/workspace/CalabashExamples/CalabashExamples.Droid/calabashexamples.apk is not signed with any of the available keystores.
Tried the following keystores:
/Users/tom/.android/debug.keystore
/Users/tom/.local/share/Xamarin/Mono for Android/debug.keystore

You can resign the app with /Users/tom/.android/debug.keystore by running:
    calabash-android resign /Users/tom/.jenkins/jobs/CalabashExamples/workspace/CalabashExamples/CalabashExamples.Droid/calabashexamples.apk

Notice that resigning an app might break some functionality.
Getting a copy of the certificate used when the app was build will in general be more reliable.
