Anki-android: AnkiDroid small widget not working

[Mornon]

Not sure why, the AnkiDroid small widget stopped working properly: it still shows how many cards are due, but if I tap it AnkiDroid doesn't open. AnkiDroid still works fine, I can open it with the normal icon, it's just AnkiDroid small stopper working, not sure why, it suddendly happened yesterday.

I also tried uninstalling and reinstalling the app, but it still doesn't work.

Reproduction Steps

1. Put AnkiDroid small widget on the desktop
2. Tap it to open AnkiDroid

Expected Result

AnkiDroid should open.

Actual Result

AnkiDroid doesn't open.

Also the Add note widget is not working.

That's odd, I have the small widget and it's still working for me, I can't reproduce this. If there was a way for you to get the logs from the device (via logcat) we might be able to see what's going on.

[Mornon]

Unfortunately I don't know how to get the logs.

[Mornon]

I tried, without success:

• deleting and replacing on desktop the widget, so it doesn't seem to be something linked to that;
• uninstalling, deleting the AnkiDroid folder and searching for more "AnkiDroid" files (no one found), and reinstalling, so it doesn't seem to be the app; it doesn't seem to be the decks either, since by deleting the AnkiDroid folder I had a clean AnkiDroid.

And since when it stopped working there were no updates it isn't due to a new version. I have no idea what's happening; is there something more I can do, some file I can try deleting before reinstalling that I missed?

[mikehardy]

I can't think of anything other than getting the actual logs

I left a comment elsewhere indicating what I think is the fastest way to do it https://github.com/ankidroid/Anki-Android/issues/5603#issuecomment-550033424

Thanks, that's very useful. I'm now downloading the log: it's some hour it's working, and it's getting kinda big (over 36 MB, right now), will you need all of it?

[mikehardy]

oh my! That is quite large. I don't think we will need all of it, but it's hard to say what we will need? Normally the interesting stuff has 'anki' in the line but if the system is failing to launch the app for some reason it may be that it isn't finding the package and the error won't have 'anki' in it at all... If you want you could share it via google drive or dropbox (or anything else) direct to me via [email protected]

[Mornon]

I uploaded it on Google Drive, you should receive the link; please let me know if I can do anything else.

@Mornon I was able to retrieve the thing and scan through it, but it's really odd to me as I don't see anything specifically in there. It does look like the MIUI flavor of android, did you receive a system update recently? You might investigate whether it is being killed by aggressive power saving - https://dontkillmyapp.com/xiaomi?app=AnkiDroid

[Mornon]

I didn't have any update, as far as I found last update was in March; the odd thing is, it seems to have stopped working out of the blue, as far as I know nothing has changed.

Anyway I was able to solve it, thanks to your suggestion about the battery saver: it wasn't that, but I started playing with permissions, and turns out this was due to "Start in background" being disabled. No idea why, since I'm sure I didn't change it and it always worked.

Thanks for your help!

power saving is useful but the vendors go to far very frequently nowadays - but hey, you know how to get android system logs now ;-)
