How can I completely erase my wallet and everything? I will try this, and then I will recreate my wallet, and see if I get the same problem again.

Ahh. I just downloaded 1.0.2, thanks for such a quick update! Alas, there is a new problem... I'll start a new topic, "Export Incomplete"

Here it is. I trimmed it down to just the relevant parts.

Wow. Solved 7 months ago?
I just downloaded biowallet sig 1.0.1 on android 2.2.1, and I am having this problem. Try to export, and get "An error has occurred during export process."

I suggest when user exports data... Allow them to browse the filesystem and specify where to save the backup.
