Edit Note confirmation crash

[marcardar]

AnkiDroid 2.5.4 (Android 6.0.1).

Try this:

1. Check "Don't keep activities" in the system's Developer options
2. Click on any deck / Edit Note / make any change / click Tick to accept
3. Observe: an error has occurred

This happens for any note in any deck. There is no error when editing a note selected via the Card Browser.

FYI

If the error occurs only with "Don't keep activities" (or better, if it is
100% reproducible with that setting turned on), it means that one of the
activities involved (usually the one below the top one) does not correctly
save and restore its state and probably assumes that its fields are
preserved when the activity is stopped and restarted, which is not the case.

I've narrowed it down to this developer setting: "Don't keep activities" -
the error occurs if that is checked.

BTW, I noticed that ACRA is throwing some odd errors and these are mentioned in this issue here. Any plans to update ACRA plugin to the latest (4.8.5)? It requires some code changes (I just saw that it introduces compiler errors when dropped in).

[zenmonkey760]

I am experiencing crashes upon clicking the check mark to confirm edit of a card. But it only happens on my tablet and not on my phone. It has been happening on all versions, both released and beta.

AnkiDroid Version = 2.6beta6

Android Version = 5.1.1

ACRA UUID = 26e71aac-7146-4f05-a37d-c75f00115e40

The crash signature from your device appears to be the same as above. Do you happen to have the Don't keep activities option enabled in the developer menu of your device?

[zenmonkey760]

Indeed I did have it set. Turning it off resolved the crash.

I'm not certain if this is the right place to report it, but I can't edit notes in the android version. Tapping the checkmark causes a 'AnkiDroid has encountered a Problem. A report is being sent to the developers.' error and the edit is not saved.

Hardware/OS
Samsung galaxy s8 plus, newest updates (Nov 2017)

To reporoduce:
click a deck to begin reviews
find a card you wish you wrote better
click ... -> edit
modify any text on the card (default card type)
click checkmark
mini-crash + error popup

frequency: 100% of the time, I can only edit using the desktop client

AnkiDroid version: ankidroid just updated for me today (nov 12/2017) but the problem persists.

Note: I'm a software engineering intern looking for side projects. It might be fun to chip in on fixing this. I've never contributed to OSS however (Java, correct?). Please let me know if anybody has an interest in this who could also point me at how to get started.

@javenschuetz

Did you read the previous comments? Do you have that setting enabled?
Also, the fix for the problem was hinted at by @flerda above, it just requires someone to go and implement it. See the development guide for some basic hints to get you started.

[javenschuetz]

My situation has changed and I won't be able to work on any side projects for a while. Pardon my not being able to follow through.

[mikehardy]

Looking at this - @timrae you interested in a PR for an upgrade to ACRA 4.x-current?
ACRA 5.x requires minSDK of 26 (!!) so that's a no-go but 4.11 exists and it did need soem code changes, but I have it working except for automated tests. Not the most important part of this issue, but it's something...and the change to 4.x-current is actually most of the way to 5 for whenever that's ready, FWIW

[timrae]

There was an issue last time I updated Acra and had to revert:

1263f84

[timrae]

Theoretically it should be fixed by ACRA/acra#344, so I think ok to give 4.11 a try, but we'll need to tread lightly. Please put it into its own PR if you do submit one.
