[QUESTION] Webdav-What has changed since 1.12-r7 - later versions instantly crash when using webdav

[EmileHirsch]

When using webdav as provider vor .kdbx file - keepass2android instantly crashes.
I had a backup v1.12-r7 (as shown in about-dialog) - which still works.

Can I help to provide a kind of errorlog ? I am subscribed to beta-channel on google play.

v1.15-r1 with cleared cache and data
Select Nextcloud, enter credentials, file picker opens, pick a kdbx file, results in crash
Select WebDav, enter file URL and credentials, results in crash

[PhilippC]

Thanks for the reports.

@EmileHirsch which version are you referring to?

If anybody can use logcat, that probably would help best. I can't reproduce the crash.

I had tried different versions e.g.

• 1.14r4 which ist available in playstore for me currently
• 1.16-pre1 from here

Maybe someone can help out with a logcat pls

I believe someone in my family is currently seeing this issue. Keepass2Android crashes on startup, probably when loading a kdbx file from Nextcloud (?). The following seems most relevant:

I attached more of the logcat to the comment. I do not have direct access to the device, so giving more information will unfortunately be difficult. This is a Xiaomi Mi 9 SE with Android 10 (MIUI Global 12.0.4).

I cannot reproduce the issue on my own device (identical setup with Keepass2Android and Nextcloud). Maybe it is something with the rather old android version?

MetrolistGroup/Metrolist#2753 looks similar and was closed with "your android version is too old".

[mgottschlag]

Also, looks like a duplicate of #3177.

Proposed fix from KRTirtho/spotube#2880:

coreLibraryDesugaringEnabled true
// use 2.0.x due to incompatibility between desugar_jdk_libs_nio 2.1.x
// and Android Gradle Plugin versions < 8.8.0
coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs_nio:2.0.4'

Great! Would it be possible to build a new keepassAndroid version around that?

[PhilippC]

this should be fixed by #3248
