I have been using K-9 Mail for many years. When the new design came out, I didn’t like it. Therefore I stayed with the old version (I don’t know which version it was).
Now I have (unfortunately) decided to install the new version 6.804. Since then, the app no longer starts. Something happens, but it crashes immediately. I can’t see any window or GUI. I have already tried some tips from the forum, but nothing has helped. I don’t want to uninstall and reinstall either, as I don’t want to lose the data (especially the emails I’ve sent. I could retrieve the others from the server, but not the sent ones). What can I do?
Data and what I have done so far:
-Samsung Galaxy S20
-Android 13
-K9 version first updated to version 6.804. This version has already caused the problem. Then updated to 6.904 via apk. Problem persists.
-K-9 cache cleared
-K-9 moved from internal memory to external memory (SD). Problem not solved. Then moved back to internal.
-Android system WebView updated to version 126.0.6478.186
-Chrome (was deactivated by me, now activated and set as default) updated to version 126.0.6478.188
-Update 28. July: trying to open K9 after switching on the flight mode. Does not solve the problem.
Which version did you have before you updated to 6.804 - this might give (devs) a hint what could have caused this issue.
Maybe try to start K9 in flight mode of mobile device in case this is caused by accessing the servers. Then you could enable logging.
Without UI it is hard to get logs. In that case I gues you would need to use adb tools on a desktop computer. Search on forum should give you some hints about it.
With the issue that you cannot retrieve the sent mails from server: this is most probably caused by incomplete folderbsettings in K9 - this is a long running topic on this forum. I hope the devs will find a solution for this soon to get at least a warning…
As I wrote unfortunately I don’t know, but I have an old Backupphone and would assume that it could be the same version. Therefore the update was from version 5.737 to 6.804 an then to 6.904 (after 6.804 caused the problem).
Switching to flight modus also does not help.
Any ideas? I am not able to use K9 what is very frustrating.
I have checked the design of version 5.737 on the Backupphone and it looks for me to ‘modern’. Therefore I would now assume that the version was before 5.737
No further ideas? Then I need to change to a another app.
Absolutely not acceptable that an update absolutely messes up everything, so that no access to the data is possible.
Only idea I still have I also mentioned before: create and send logs. If not possible by K-9 UI then you need an external computer and create it with that:
