Do you know when this happens?

[Axxxolotl]

Unfortunately, I did not notice a certain pattern. I got a new phone about 2 weeks ago. During this time, this appeared 4 times. This happened both when using the "nextcloud" application itself, and while using other applications. Once this error report arose simply when I looked at the screen without launching any applications.
In the phone settings, the application is allowed to work in the background.

[albertomna]

It also happens to me often, especially after the synchronization of some contacts with Davx5.
It's happening more and more frequently.
Android 9 Operating System

[Chartman123]

I get the same crashes. It seems to me, that the crash occurs when there is a new notification on the server and the message gets pushed to the client.

[albertomna]

Yes i confirm this. Every time that i try to change an information in my Contacts, the app crashed.

[tobiasKaminsky]

This is strange, we did not changed anything in this matter.
@albertomna do you change this locally on your phone?

[albertomna]

@tobiasKaminsky Thanks for the reply. No, the change was done directly on Nextcloud on PC through Browser. I sync with the Davx5 application, contacts and calendar,and seems that everytime i change one contact or calendar on My PC through Browser, the smartphone app crashed

[tobiasKaminsky]

and seems that everytime i change one contact or calendar on My PC through Browser, the smartphone app crashed

@georgehrke do you have an idea here?
Are there any push notifications send?

[georgehrke]

If anything it generates a new Activity, but no push.

cc @nickvergessen

[nickvergessen]

Yeah, contacts dont even have activites atm.

[tobiasKaminsky]

I can only reproduce this when I install our gplay app on an emulator/device without any google services.
If you have a regular device with play services, then this error should not happen.
if you have a FOSS-only device, please use the version from Fdroid.

[Chartman123]

I've installed the app from Google Play and have the Play services on my device, too. Should I provide you with a logcat?

[tobiasKaminsky]

@Chartman123 it might be worth a try :+1:

logs-2019-10-08-16-57-06.zip
These are the logs for the login 2FA using Nextcloud notification. As soon as I clicked on the button in the web interface, the app crashed.

[ezaquarii]

Current firebase messaging is available in version 20. We're using 17.

Since we have devices that fail consitently, we could ugrade to 20 and try it out.

[tobiasKaminsky]

Hm. I tried to update it locally to 20, but it did not helped.
What instead helped was to remove this:
https://github.com/nextcloud/android/blob/master/build.gradle#L48-L50

But this is something we have to verify what the impact in regard of privacy is.

EDIT: what I do not get is, why this is happening only on latest Android devices. They should still use the same "old" firebase implementation we use.
Or Androids SDK is behaving different and enforces somehow analyticts.

This request did not receive an update in the last 4 weeks. Please take a look again and update the issue with new details, otherwise the issue will be automatically closed in 2 weeks. Thank you!

[Chartman123]

Just a quick note: After upgrading my phone to Android 10 and reinstalling the Nextcloud app everything works fine again.

[Chartman123]

And it came back after some time...

[AaronADev]

I can confirm this issue is now re-occuring especially when 2FA Notifications are enabled. I have a Galaxy S9+ that this happens on. It must be related to the SDK version or something related to the phones they occur on. I have an older, Samsung Galaxy Tab 8.0 that this does NOT occur on during the same notification request.

Here is an additional stack trace from my phone:

@tobiasKaminsky Any ideas?

Thanks ya'll. Hope this gets resolved soon!

[JanHellwig]

I had the same crash twice today. Both were just there when unlocking my phone. There was a notification due to an update for the TOTP plugin in my Nextcloud and I think it might have been related to that as nothing changed in my setup for a while now.

I second this. I basically see the same crash on a bi-daily basis.

Why closed?
