4. Wait.

Hey @adambuchbinder, Thank you for reporting the issue.

I tested it on my device and on version 4.2.1~14b6c455b. It is working fine for me.

@adambuchbinder Does that always happen, or just sometimes?

[rohit9625]

I also experienced this several days before and thought it might be due to the unavailability of categories for some text. However, I did not recall for which text the category was blank in my case.
@adambuchbinder can you tell us which category you searched for?

[adambuchbinder]

It doesn't matter what I search for; nothing shows up in the category box. See the video. (Too large to attach, on mobile so can't reencode.)

When a technical error happens here we should display a snackbar with the message.

Even when the reason is that there is no internet, we do not show any error message:

What is the cause that categories are not being fetched? Did you find anything in the logs?

[adambuchbinder]

Sorry, I'm not familiar with some of the workflows here. How do I look at the logs to find out why categories aren't being fetched?

@adambuchbinder in main menu, Settings, Send log file you can get the logs.

[adambuchbinder]

Thank you for your patience; here's what looks like the relevant log.

Interesting . That ERROR:

[CategoriesPresenter$onAttachView] : android.database.sqlite.SQLiteException: 
no such column: description (code 1 SQLITE_ERROR): , while compiling: 
SELECT _id, name, description, thumbnail, last_used, times_used FROM categories ORDER BY last_used DESC

sounds like there are columns missing from internal SQL database. That should not happen normally (or the app wouldn't be working for anyone if such bug made it to the release). I'm not very familiar for code there, but I had to hazard a guess, I would guess that there was some previous version of Commons app installed before, and that upgrade to newer version didn't quite work, leaving the database out of sync with the app.

If that guess is correct, then uninstalling (which will remove local database) and installing Commons app again (which will recreate it) should fix the issue. (provided you don't have some kind of os-based backup-app-data-to-cloud-and-restore-it-automagically-on-reinstall shenanigans enabled; in which case this might work instead: Android OS settings / Apps / Commons / Storage / Clear data). Would you be willing to try that @adambuchbinder ?

(full log also shows a case of badinteger / missingtitle ERRORS, but according to #5244 those are benign and may be ignored)

[kanahia1]

@nicolas-raoul, Should we add how to get logs in readme.md file so that non-technical people can easily get through this.

[adambuchbinder]

You're right; clearing the app data fixed it. Thanks! (This actually persisted across a phone migration, which... thanks?)
