Add ex-/import of the database

[MaDill]

It would be nice to have a ex-/import feature. Or at least the possibility to backup the app via Helium. This would help when setup a new ROM. I know this can be a security problem, but maybe make it optional and only available for a new database. Create a message which inform the user when first time run the app, that this feature can only get activated now or never.

I just backuped/restored my phone with oandbackup and was very surprised when I found that all my keys in otp-authenticator are gone, even when all of data/net.bierbaumer.otp_authenticator was restored. Please provide a way of backup the data and show the key for the internal encryption. Thank you very much for the awesome app!!

I just attempted to backup with oandbackup as well. It never seems to finish for me. This would be really helpful.

This would be very helpful as I have no chance to get my keys out of an old phone in case of a device change. Is it planned to implement this feature soon?

+1 on this, especially in light of issue #8.

This repo seems to be unmaintained, but there is a active fork, which is also in F-Droid: https://github.com/kckrinke/onetimepad
