If you run into a crash
Crashes are automatically recorded in a crash log, called
log-AquaMail-crash.txt and located at the root of your device’s memory card.
Please send it as an attachment to kmansoft / at sign / gmail / dot-com.
This file does not contain any logins or passwords or message text.
Creating a log if something doesn’t work right
In the application’s settings, open “Debug” section (at the bottom) and enable “Debug logging” there. Set “Log output location” to “File (log-AquaMail.txt)”. You will need to enable “Log raw data (session data)” most of the time, if the issue is related to specific message(s) or account(s).
Once logging is enabled, please repeat whatever was causing the issue.
After having done this, please send the log file to kmansoft / at sign / gmail / dot com (and disable logging afterwards). The log filed is called log-AquaMail.txt and is stored at the root of your device’s memory card or large built-in storage.
As of 18.104.22.168, attaching logs is easy: there is a menu item for this in the compose window (last one).
The log does not contain your email account passwords.

Occasionally the unlocker reports “Error communicating with Android Market licensing server”. This is a bug on Google’s side, is known affect other apps, but is going unfixed since about April/May 2012. I do have a workaround for this one, please contact me at the email above.
