Android Question SOLVED Firebase issue for nougat 7 huawey phone. Google framework was disabled.

[tigrot]

Hi everybody
I have an app which polls another smartphone via firebase messaging. If poll is made via wi_fi it's ok. If android 7 is on 4g the app doesn't work. If it's on wi--fi and the counterpart on 4g it's ok.
Anybody knows the reason?

How do you poll another device with Firebase messaging?

 

[tigrot]

I have stored the key on a db. I use phone # to access it then use to contact the counterpart. The app worked for 10 months in beta on Google store and was tested on all possible Os's on wi-fi and 4g 3g.

 

[tigrot]

If you want to test search 'personal finder' on store. The first app from logic data is the one.

 

[tigrot]

One additional info: i update the key on every proper situation like startup, key.change event...

 

[Erel]

Sorry but I still don't understand. You are sending push messages from one device to another and the other device doesn't receive it when it is connected to 4G?

 

[tigrot]

Not exactly. I have two roles in this App: server and client. They are present at the same time. The client asks the server its position and it answers with coordinates.
What I see is that the server receives the poll request and answers, but the client doesn't receive the answer. I use the passed key to answer. This happens only if the Android 7 side is on G4/G3. If it's on Wi-Fi everything is ok.
I have read somewhere that A7 is sometimes faulty with Firebase Messaging Key.

Any energy saving setting active (took me hours to find that on my P8 Huawei). There might be additional features like WiFi/4G

There might be additional features like WiFi/4G

During this poll the app is active. Internet is active because i'm able to check a mysql db.
I have read about a firebase issue on 7. Since upgrade to oreo is due in few days I'll check!
Thank you everybody! And Happy New Year!

Just tested on my Huawei Mate 10 lite via 4G. No problems.

 

[tigrot]

Maybe there is something with my Honor 6+. Do you have Android 7 on 10 Mate? I have the same issue if I loop back the request! My provider is Vodafone.

 

[tigrot]

I have just tried the loopback. If Vodafone no way. If wi-fi and no restart in the middle everything is running at its best!

 

[KMatle]

Yep, Android 7. Will try a restart. Usually the service is re-started if necessary. Do you get any messages when SENDING a message to the device? (e.g. "not registered"). Are you REALLY sure that the app/your device has the correct settings in the Huawei energy saving menu? Will upload a small demo project with you can try with (B4A/B4J).

 

[KMatle]

I did a test with the app's attached. All working fine even after a restart (without any "start at boot" option or others).

1. Edit the B4A app (just copy the google-services.json file to the folder) and start it (check that the energy setting "stop app when screen is turned off" is set to OFF. As it seems Huawei has learned from that because on my new one it is set to OFF, on my P8 it was automatically set to ON for unknown apps. Even WhatsApp was stopped and the Google calendar did not update until Huawei brought an update).

2. Copy the device's token (see the log) to the B4J app and enter your server key (see the FCM console of your app)

Take a look at error messages. Of course it's a simple example which doesn't store the token to a database. Just for a quick test.

just copy the google-services.json file to the folder

Sidenote:
AND change the packagename to the app defined in the json file you downloaded from Firebase.

Or not?

 

[tigrot]

I have a sort of timeout when receiving from server. As a poll scheme i send a request and wait for delivery for a two minutes or so. In the meanwhile i send a poll every 30". I don't care for multiple answers because they are real time coordinates.

 

[tigrot]

I have this phone since 19 dicember. I never tested messages on G4 network. Something blocks messaging. My bank's App doesn't work as well.
I'll do further testing...
Grazie ragazzi!

Seems:this is not the solution to me: read the next post for my real solution

It's a known issue for Honor 6X
Here is solution:
This is for EMUI 5 (Android 7).

The final solution for Honor 6x BLN-AL40 (Android 7.0 EMUI 5.0):
1. Clean start: reinstall stock ROM over eRecovery
2. Install Google Installer (same here)
3. Install GMS Core
4. Restart

Google framework was disabled for mobile network. I spent 1 hour in chat to explain an agent what is Google Firebase and i were defeated by her . No way to explain. Then i started to search for a logical setting about this issue.
I include the setting for this use.
Happy week-end
