Hello @fgiering , I couldn't reproduce the issue on my devices unfortunately, but I have an idea of what's causing it and implemented a fix. I'd need your help to confirm it actually works.
I built a new version of the app for you, it can be downloaded from https://github.com/nextcloud/android/actions/runs/32106006002/artifacts/9313330308
To test this change/fix you can simply download above APK file and install and test it in parallel to your existing Nextcloud app.
You can also use the following QRCode to install it, if it's more convenient to you:
(please click on link to get QR code displayed)

Thank you for your collaboration!

[fgiering]

Thanks for having a look at this.
With your fix the stack-trace is not appearing, but the app crashes anyway and just disappears.
Anything else I can provide for making this debugging easier?

[daniele-verducci]

Oh, that's strange. Having the ADB logs could be helpful.
Also, is it crashing before or after showing the application chooser? (i.e. when you click on "Share internal Link" or when you click on "Copy to Clipboard"?)

[fgiering]

Its crashing after showing the application chooser, when I click in this application-list on "Copy to Clipboard".
I will see If I can get the ADB logs.

ADB is giving the same Java Exception I got on screen before:

But I just recognized the line "cmp=com.adobe.cc/.share.CopyToClipboardActivity" and found that this is probably an adobe-App feature. Then I found an other "copy link" option which looks more native, but haven't seen until now... and "copy link" works fine on both versions of the app.

[daniele-verducci]

Yes, I noticed in the first stack trace, so I tought we were selecting the wrong intent from the list and added a filter on the package name. But maybe it is added by the system and has nothing to do with Nextcloud.
It would be helpful to know which app provides that intent so I can reproduce the issue on my devices. Also, may be worth trying to use the same "copy link" from Adobe while sharing from another application, just to see if it crashes anyway...

Thank you for your collaboration!
