    Didn't fix the broken key problem, either, it still says no suitable key found when I try to decrypt something. Any ideas?

    I had to generate a brand new key after it updated to 2.9.2, for some reason, my main key was no longer mine and I don't have any backups of the key for some reason (thought I had but must've deleted accidentally..). Other than this, it's a great frontend for using OpenPGP/GPG Keys on Android.

    But it already looks great. It generates keys, it lets you share them. What more could you want?

    Having problem with the guardian project version. Installing this to provide alternative for gpg encryption. Now what? Just exchange gpg keys and start a super secret message.
