Hi Amul. I finally got the emulator working to test this. I have encountered the same issue, but after reinstalling the app, it was fixed. Maybe the keystore got corrupted between test builds. I suggest you to try deleting the app and start with a clean build. Hopefully this will fix the problem for you, too. Please let me know if this fixes your problem.

I am closing this now, since this not really reproducable.

To @AmulAbasana and anyone who has encountered similar errors: Please update this issue.

On Android the key becomes invalid if Screenlock type was changed or finger are added.

see #58

This error will be resolved with #54
