Note that it already occurs when you have two shortcuts to two distinct decks

Hello, could I be assigned to this please.

[Arthur-Milchior]

@leobugeja You don't need to ask usually. If you have an idea how to fix it, or at least investigate, you can just state you'll work on it. There are not so many devs that we need to manage who does what

[leobugeja]

The problem appears to be that when using the shortcut to open deck review, that activity gets put ontop of the previous deck's review activity and when using the back button to close the top activity, updateCardAndRedraw does not get called (which inturn skips setting the current card) on the previous/old review activity and so we get the error not at top of queue.

@Arthur-Milchior, I can see two solutions:

• On a back press call updateCardAndRedraw for the previous/old activity.
• When using a shortcut or widget to open a deck (or alternatively on back press during a review activity), close other review activities so on the back press, the user is navigated to home rather than to another review session.

[Arthur-Milchior]

Please close other reviewer activity. We are not expected to support multiple reviewer opened simultaneously

[Arthur-Milchior]

I'm reopening this isse because it regressed. I don't know why. @leobugeja if you have any idea why, it'd be great.

Also I guess next time we colse it we should really have some test to avoid a new regression

[Arthur-Milchior]

I think I figured out what went wrong. We don't open the reviewer directly anymore. We open the IntentHandler. It's a distinct activity, so addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP or Intent.FLAG_ACTIVITY_NEW_TASK) won't clear it

Came across this myself as well.

Debug info:

AnkiDroid Version = 2.20.1 (e32a82c33646807ea19623c9c88be38965bc07e6)

FSRS = 1.4.3 (Enabled: true)

The steps to reproduce seem to be the same as the original post, but here is my description for completeness:

• Make sure you have the AnkiDroid widget with two different decks A and B
• Start doing reviews for A
• Go back to home screen via home button
• Press B on widget

At this point, Anki should have opened again with B

• Press back

At this point, you should see deck A again

• Review card, including grading ==> Error: not at top of queue

Hope this is useful.

TL;DR: Cannot reproduce on newest beta

As suggested by @mikehardy , I tried to reproduce after updating to the beta.

I updated by signing up to the beta on Google Play, installing the update, cleaning the cache, and then restarting my phone.

Debug info:

AnkiDroid Version = 2.21.0beta4 (3b5489b76c7aa9944f5d62212fa3e09aca35941d)  
Backend Version = 0.1.54-anki25.02.7 (25.02.7 98253c81cb3c4d203acec48d6eae6b488bf484d0)  
Android Version = 13 (SDK 33)  
ProductFlavor = play  
Device Info = OnePlus | OnePlus | OP555BL1 | IV2201EEA | IV2201 | mt6877  
Webview User Agent = Mozilla/5.0 (Linux; Android 13; IV2201 Build/TP1A.220905.001; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/137.0.7151.115 Mobile Safari/537.36  
ACRA UUID = a9fbcbbe-fb1f-43fe-9575-39915fdfc027  
FSRS = 2.0.3 (Enabled: true)  
Crash Reports Enabled = true

I cannot reproduce the error anymore, in the sense that

• Press back

At this point, you should see deck A again

does not seem to apply anymore. Instead, pressing back at that point returns one to the deck overview.

I tried to mess around a bit by manually going from that point to the different decks, but I didn't seem to be able to reach that error anymore.
