IllegalStateException: Can not perform this action after onSaveInstanceState

[eX00r]

Hello,

first thank you for your great work with this app!
I was using it a long time without any issues. When I bought a new phone and installed NC Deck App on Android I was not able to sync the Decks from my instance. It is possible to sync with a new user account which is only subscribed to few decks but not with my own User Account which is subscribed to several huge decks. The device starts syncing, my profile pick is shown in NC Deck App and it seems to successfully sync until Deck 4 of 15 and then crashed with the following bug report. This happens with PlayStore as well as wit F-Droid Version.

Full Crash:

Dear @eX00r,

did you try clearing the storage as described in the FAQ and reimport your account? Ideally with a strong and reliable internet connection like Wi-Fi.

You might also want to try to unshare boards shared with you and then reshare them step by step to reduce the load for the critical first sync? Try tapping on whitespace to avoid the app getting suspended by Android. (I am aware that this is actually an app issue).

If everything goes wrong, I can offer you of course to refund the money you spent at the Play Store.

Kind regards

Hello @stefan-niedermann ,

thank you for your repsonse.

Cleaning the storage and reimporting did not help.

What did the trick finally was unsharing all boards with my account, then sync the Deck app after a clean installation and then re-sharing all accounts. This actually is not a solution which really could be considered a solution as it means transferrring ownership of my own decks to another account to actually becomming able to unshare them with my original account and the reverse the whole operation.

Just fyi if you did not know already, the app "deck ng" was able to sync all the decks from the beginning while NC Deck on Android was not. Maybe it's worth investigating what is done differntly there.

best regards

I am getting the same error, with Deck android 1.24.1 (storage and cache removed) and NC server 28.0.3 (unfortunatly, I don't own the server so I have no idea about the NC desk server app version).
