Hi.

I haven't been able to sync my anki droid in a long time now. As soon as I try, the app freezes and does nothing. I close it and reopen to keep using it.

Thanks

Hi there - sorry about that, if this were me it would give me a bit of anxiety - as sync is how I back things up in case my phone dies or is lost for whatever reason.

First things first, do you have any another method of backing up your collection? If not you should seriously think of doing a full collection export and saving it somewhere as a critical data protection item - before doing anything else.

That done, can you see what the sync settings look like, to make sure they are in good shape?

• make sure, in system settings, that AnkiDroid notifications are enabled - we use a persistent foreground notification to display sync status
• make sure you can log in to ankiweb directly using a regular web browser to https://ankiweb.net
• try to sync, does it work now?
• in AnkiDroid settings -> sync:
  • select the AnkiWeb email address and "Log out" in the following screen then hit back so you are on sync settings again
  • select AnkiWeb account and try to log in again
  • try to sync, did it work?
  • in the Custom Sync Server settings enable "sync url" and type in something like http://example.com, but then disable it
  • try to sync again, did it work?

Hopefully something in there does the trick.

Thank you so much for taking the time to respond! Enabling Notifications did the trick. Thanks again. Big relief.

That's great to hear that worked for you!

For us that's a problem though. I've altered the title of this issue slightly and we'll need to investigate and fix it here.

If notification permission for the app is removed we should handle that correctly with some user messaging and sending the user to settings to fix it, vs hanging of course.

Cheers

@mikehardy could this be the ANR you mentioned?

[mikehardy]

Perhaps yes, the thought occurred to me but without logcat hard to say. Certainly an easy thing to tackle and it will likely affect it positively
