@AndyScherzinger Gonna give this a try!

kartikarora on 1 Oct 2016

Awesome @kartikarora!

AndyScherzinger on 1 Oct 2016

@AndyScherzinger I'm unable to reproduce the exception since I don't have a nextcloud server deployed anywhere. Do you have any test credentials that I could use?

kartikarora on 2 Oct 2016

hi @kartikarora I do not have a testing instance of Nextcloud but @stp-ip might be able to help you out here :smiley:

AndyScherzinger on 6 Oct 2016

you can try the instance on demo.nextcloud.com user: test pw: test, but it gets reset from time to time and is not perfect for sensitive data, but if that's not an issue, test away.

Got the app running. Thanks @stp-ip .

@AndyScherzinger Do you have a more detailed stack trace? The one posted above does not indicate which Java file raises this exception. Seems like an incomplete trace to me!

kartikarora on 7 Oct 2016

@kartikarora unfortunately these are the complete stack traces as reported by the Google Play developer console. I discussed this with @tobiasKaminsky and it is related to the list adapters and is likely due to a race condition where it seems that the rendering/filling of the list is done before the data is present/completely fetched.

AndyScherzinger on 7 Oct 2016

👍1

Alright I'll start debugging the ListView then. Bug hunt mode on!

kartikarora on 7 Oct 2016

@kartikarora Awesome! :tada:

AndyScherzinger on 7 Oct 2016

I tried all visible list views, could not recreate the issue. Or any crash for that matter! There are so many ArrayList instances and adapters! :confused:

kartikarora on 16 Oct 2016

hmm, @tobiasKaminsky any ideas or hints?

AndyScherzinger on 17 Oct 2016

I got the same bug on android 6.0. So, what's the solution?

duoduoluo on 29 Nov 2016

Hi @duoduoluo,

this has been fixed in the latest library release, see PR https://github.com/nextcloud/android-library/pull/24 and is related to the hash function.

AndyScherzinger on 29 Nov 2016

Needs (yet unreleased lib version 1.0.10)

AndyScherzinger on 5 Dec 2016

explicitely repopened @tobiasKaminsky since this is the number 1 reported crash in Google Play for the app 1.0.0-1.4.0, so scheduling the fix for 1.4.1

AndyScherzinger on 5 Dec 2016

still haven't found a way to reproduce this issue, so postponing

AndyScherzinger on 3 Jan 2017

hi, I got this problem recently, any solution or hint? thx.

IvanAldrich on 21 Feb 2017

@IvanAldrich Could you explain the steps how you got the issue? It'll help us recreate and debug the issue.

kartikarora on 21 Feb 2017

@kartikarora when long press a item in the list, we got a dialog to delete the item. we delete the item from the data source and after that, we pick a new list from db to and notify change for the adapter. It happened once so far and i have no idea how to recreate it.. I done know wether it's useful or not that i add a footerview for the listview which's visibility is set Gone when the list is empty.

IvanAldrich on 22 Feb 2017

Also reported via #760 now (already closed it).
@mario @tobiasKaminsky any idea how to reproduce this? I tried again browsing through my folders like a monkey but no crashes ever (since version 1.0 I never had one!) while I have to say I am running Android 7+ (which is probably the "fix")

I checked the Play console and it is one of the most reported issues but it is also a Android 6 only reported issue (no other Android version reported this issue!!!)

AndyScherzinger on 19 Mar 2017

@AndyScherzinger in my case i got this exception in Android-Version:4.2.2, do you mean that after android 7 this issue has been solved?

IvanAldrich on 20 Mar 2017

I have no clue :-/

tobiasKaminsky on 3 May 2017

怎么解决？

meicuihui on 4 Jan 2018

I am facing this issue on Android 6.0 with LG G Stylo device. Is there is any fix for this HeaderViewListAdapter.java:164 of list view which is causing indexOutOfBoundException.
