Push notification are disabled

[XueSheng-GIT]

Steps to reproduce

1. Install Talk 15.0.1 (GPlay)
2. Enter user credentials to login

Expected behaviour

Notifications should be enabled and available.

Actual behaviour

Message appears (just for a couple of milliseconeds) that push notifications are disabled. I didn't find any way to see this information afterwards (e.g. settings menu). Notifications for other apps (including nextcloud) work just fine. See further details below (Additional information).

Still trying to get push notifications working again. I removed talk app, removed the talk pushhash of the user (mysql table oc_notifications_pushhash), installed talk again and logged in with the user. Message still appears that push notifications are disabled and there's no new pushhash created. Why isn't a new pushhash created???

@mahibi Any hint how to debug this issue?

[timkrueger]

Hey @XueSheng-GIT. Thanks for your report.

I tried to reproduce that issue without success.

• Is it possible for you to test with an other instance? Or did you already?
• Is it possible for you to collect logs with Android Studio?

[XueSheng-GIT]

@timkrueger thanks for trying to reproduce!

* Is it possible for you to test with an other instance? Or did you already?

* Is it possible for you to collect logs with Android Studio?

I did try three different nextcloud instances (two running latest NC24, one running NC25). All with the same issue.

Never worked with android studio so far, but will try to gather some logs.

Just as an additional side note: the Huawei Mate40pro does not come with GAPPS, but I'm using microg to get push notifications. This works quite well and works without issues for the regular nextcloud app. Talk is registered to receive notifications, but according to microg no messages are received. I'll try to get some logs and will report back.

[XueSheng-GIT]

@timkrueger I did gather the log with adb and logcat (I assume android studio does the same). I don't feel comfortable publishing this log right here. Can I send it directly to you somehow?

UPDATE: Just had a quick look at the log myself and found the following lines:

10-31 15:26:23.516 27499 27797 W GooglePlayServicesUtil: com.nextcloud.talk2 requires Google Play services, but their signature is invalid. 10-31 15:26:23.516 27499 27797 W PushRegistrationWorker: executing PushRegistrationWorker doesn't make sense because Google Play Services are not available 10-31 15:26:23.518 27499 27760 I WM-WorkerWrapper: Worker result FAILURE for Work [ id=f4c5db59-4f49-4b01-a8d1-371161a3cfb9, tags={ com.nextcloud.talk.jobs.PushRegistrationWorker } ]

Seems it's really related to the missing GAPPS and microg. But as said earlier, other apps (including nextcloud itself) work just fine with microg and push notifications!

[XueSheng-GIT]

@timkrueger Do you still need the full log or is the extract mentioned above enough?

[timkrueger]

@timkrueger Do you still need the full log or is the extract mentioned above enough?

Please sent the logs to tim.krueger at nextcloud.com.

[timkrueger]

Is it possible for you to re-install Nextcloud Files? If push then still working with Files, we're more sure that this must be an Talk issue.

[XueSheng-GIT]

I did already re-install nextcloud files. But now did again (removed the app, installed again and entered the account details). Push notification is working as expected. I took a logcat, just in case it might be helpful. Should I send it to you?

[tobiasKaminsky]

@timkrueger I can test it tomorrow with microG, if needed.

[XueSheng-GIT]

@timkrueger I can test it tomorrow with microG, if needed.

One aspect which might be considered is that "signature spoofing" is not possible on (recent) huawei phones. I assume that microG is currently working without issues if signature spoofing is enabled/available.

[tobiasKaminsky]

Signature spoofing is indeed needed for a working microG.

[XueSheng-GIT]

Signature spoofing is indeed needed for a working microG.

I assume SafetyNet is the biggest issue if signature spoofing is not available. But signature spoofing should not be a requirement for push notifications. I'm using microG since nearly two years without signature spoofing and push notifications are working just fine (including a couple of banking apps and nextcloud files of course).

[tobiasKaminsky]

I am not that into it, but I understand that signature spoofing is needed to "trick" all google calls to be redirect from official gplay services to microG:

https://github.com/microg/GmsCore/wiki#system-requirements

Your Android system needs to support signature spoofing so GmsCore can pretend the existence of the official Play Services to applications calling Google APIs.

In your logcat I see:

10-31 15:26:23.516 27499 27797 W GooglePlayServicesUtil: com.nextcloud.talk2 requires Google Play services, but their signature is invalid.

which might indicate that this is not working.

[tobiasKaminsky]

But indeed it is strange that only Talk then needs it, as Files works.

[tobiasKaminsky]

Hm. While debugging this, I get a 409 when registering to https://push-notifications.nextcloud.com/devices

@nickvergessen do you know what this means? That there is already the same push token? But I installed Talk from scratch…

[nickvergessen]

do you know what this means? That there is already the same push token? But I installed Talk from scratch…

The device identifier (a hash of instance id, user id and auth token id) already is registered with a different user public key. I guess it can happen with dev instances and you didn't unsubscribe from the push server when the old account got removed.

This only affects unlucky developer cases, as on a real instance you can never get the same combination of instance + user + auth token, because the auth token is auto increment. Only when the instance is reset it can happen.

[XueSheng-GIT]

I'm on talk 15.1.1 now and issue is still present.

[lukaszsobala]

I have the same problem.

[redtomaka]

I have exaaclty same issue, nextcloud files works like a charm, nextcloud talk does register to microG but doesn't receive any notification (huawei P40 with microG, nextcloud files & talk from GPlay)

[jenalj]

Me too, using F-Droid versions on an unrooted Samsung and a single, non-developer instance. Tried reinstalling multiple times in every combination I could think of, always "push messages disabled", and "no device found" .

"Nextcloud Services" polling app works, I 'm using that in the meantime. (And whether you catch this bug or not: Thanks for your efforts!)

[lukaszsobala]

I fixed this by switching from lighttpd (which isn't supported anyway) to nginx.

[jenalj]

I fixed it by uninstalling the F-Droid version and installing from Google Play instead.

The F-Droid version of Talk works with MicroG -only-, it's not compatible with Google Play Services, as it turns out.

[tobiasKaminsky]

Fdroid version is FOSS, thus it cannot have any receiving parts of push notifications (as those are closed source by Google).

[jtxnn678]

Issue still exists on NC.Talk 16.0

RedMi 11Pro 5G (All permission) Screen doesn't wake up upon receiving call & text, no notification or ring tone played.

[4r1-60ld]

Issue still present. Using latest Nextcloud-AIO. My Phone is a OnePlus 7 Pro with latest crDroid installed. When trying to enable notification, there is a message underneath the toggle stating "At your request, Android is blocking this category of notifications from appearing on your device". Have tried both F-Droid and GPlay version of Talk apps. Same issue. (v17.0.2)

[4r1-60ld]

Oh... and btw. Latest Nikgapps Core installed.

[XueSheng-GIT]

But indeed it is strange that only Talk then needs it, as Files works.

@tobiasKaminsky Unfortunately notifications are still not working for Nextcloud Talk 17.1.0 RC1, altough it works for Nextcloud app itself without issues. Did you find out why Talk needs to verify the signature while Nextcloud itself does not?

Please help me, I have created my apk from the same source code without modifying anything and when I install and log in, the message appears: PUSH NOTIFICATION DISABLED .... Is there anything else to do?

OBS: I use source code version apk 17.0.2

[mahibi]

Please let me know if the issue is fixed when v18.0.0 is released. It will introduce fixes for notifications and account deletion. If you already want to try out the release candidates, feel free to join https://github.com/nextcloud/talk-android#via-google-play

[XueSheng-GIT]

@mahibi I've updated to 18rc2, deleted one of three active accounts and added it again... notifications are still disabled.

Anything special which has to be done after upgrade?

[foegra]

same problem here with oneplus phone, stock firmware.

[mahibi]

I recently created a diagnosis screen and checks for permissions in https://github.com/nextcloud/talk-android/pull/3558 It's not released yet, but it would be interesting if you could try it out and paste the reports here. If you're willing to do so, please install apk from https://github.com/nextcloud/talk-android/pull/3558#issuecomment-1888707964 (or from alpha release channel: https://github.com/nextcloud/talk-android#via-google-play-1)

Then go to settings (and check if any permissions are marked with red color). Then open diagnosis screen (see advanced section in settings), copy the report (upper right corner) and paste in here.

[bene64]

I also didn't get notifications with my installation (just until now). Below the information from the diagnosis screen.

What's not in there:

• Android is LineageOS for microG 21
• App is in the work profile (via Shelter), but microG + FCM notifications works there too for other apps
• microG settings were all on (Device Registration, Cloud Messaging, SignatureSpoofing, ...) except for SafetyNet
• as I read in https://github.com/nextcloud/talk-android/issues/2529#issuecomment-1315761272 maybe SafetyNet could be the root issue, I enabled it. After restarting Talk, it successfully registered a Token and in microG Cloud Messaging

=> So SafetyNet is probably the missing part in some of the cases here

So a check + warning for missing SafetyNet could probably be a valid workaround here. But I would also appreciate support for UnifiedPush (https://github.com/nextcloud/talk-android/issues/257) 😉

=> So SafetyNet is probably the missing part in some of the cases here

Thanks to share this information @bene64. I'll have to read up on it a bit..

[XueSheng-GIT]

SaftetyNet depends on working signature spoofing. Thus, missing signature spoofing is generally the issue if apps complain about missing gplay. There are devices (like my Huawei Mate 40 Pro) on which you cannot enable signature spoofing.

But, the main point is that signature spoofing is not required for push notifications. Push notifications are working for most of the apps and if you installed Talk long time ago, push notifications are also working properly because the device was already registered. E.g. I own two Mate 40 Pro. On one of them I uninstalled Talk and I'm not able to get push notifications working again. On the other device it is just working because device registration was done differently back at the time.

@mahibi Talk should just try to register for push even if gplay is "officially" missing. Some other apps are e.g. complaining about missing gplay and notify that the app may not work proberly, but still work without issues. Should be the same for Talk.

[XueSheng-GIT]

@mahibi I'm on Talk-Android 19.0.1 now and this issue still persists. The Nextcloud app itself is still able to register for push notifications on the same device (still without signature spoofing). Isn't it possible to use the same push registration like the Nextcloud app does?

Alternatively, is there a way to register for push manually somehow?

[XueSheng-GIT]

I had another look at this issue... Just as a reminder: push notifications for Nextcloud android are working with no issues (for other apps it's also no issue on my Huawei Mate 40 Pro). Only Nextcloud Talk does not work as expected.

For Nextcloud android, the check for available of Gplay is done here: https://github.com/nextcloud/android/blob/f445f0f34d77c946aa61cf5f6538203f5aec431e/app/src/gplay/java/com/owncloud/android/utils/GooglePlayUtils.kt#L19-L33

For Nextcloud Talk this check is done here: https://github.com/nextcloud/android/blob/f445f0f34d77c946aa61cf5f6538203f5aec431e/app/src/gplay/java/com/owncloud/android/utils/GooglePlayUtils.kt#L19-L33

The main difference seems to be how resultCode or code are defined. Actually, those different approaches are not clear to me (I'm no developer).

resultCode for Nextcloud Talk is 9 (SERVICE_INVALID) on my device.

Thus, I tried adding this code as acceptable and changed https://github.com/nextcloud/talk-android/blob/60ecfa72c592a5a7341f1ebb255ac0ebe3c214ed/app/src/gplay/java/com/nextcloud/talk/utils/ClosedInterfaceImpl.kt#L54 to

return if (code == ConnectionResult.SUCCESS || code == ConnectionResult.SERVICE_INVALID) {`

Now push notifications are working again on my device!!!

@tobiasKaminsky as said, I'm no developer. But maybe you can explain, what the difference is in definition of code vs. resultCode (see linked functions above). As code is SUCCESS and resultCode is SERVICE_INVALID on the same device. Finally, I do understand that some Huawei devices are lacking proper gplay support, but push notifications do not depend on available signature spoofing (microg).
