K-9 Mail not working with Openkeychain K-9 does not seem to find the installed Openkeychain app. OKC works fine and so does K-9 except for this problem. Both programs have been installed from F-Droid and are the the latest version. I am using a Moto G ("falcon") with ParanoidAndroid 4.6b5 without Gapps. APG used to work.

Thanks in advance for any help.
Apparently on the "Accounts" screen, one has to long press the account.  Menu will pop up.  Click on "Account settings".  Another menu will pop up.  Click on the "Cryptography" item at the bottom.  The Cryptography menu will open.  Click on "OpenPGP Provider".  By default, "None" is selected.  Click on the "OpenKeychain" and you're set!

Hope this helps!
