You need to go over the tutorials and learn how services work.

my service and my app work perfectly, I only have problems with the huawei P8, all other devices work perfectly, the services remain active and do not lose a package!

My question was very simple: is there a way to keep always active service on the huawei P8? (without using the push..., maybe with some loop of intent, maybe intercepting the moment the service is interrupted)

It depends witch operation system you use. However the whit b4a 8.3 and oreo ,the starter service is never killed until the process is alive. You can check periodically into that service if your service is still active and start it.

I have solved into a project where my app was always on top ( android TV box used as server) following an Erel council , I create another app as a watchdog and every 2 minute that app send a start command to my server app, in that way my app is always alive 24/7

Yes, I did it, but the huawei P8 does not work, as soon as the user presses the power button to put the phone on standby, the process is killed, and then the socket that runs on a service no longer receives messages. I also tried to do another service that checks every 2 minutes if the primary service is active, this solves the problems on other phones, but on the huawei P8 also killed this, this and primary service. I have look in huawei setting and is all ok, I don't find one solutions.

PS.
I use B4A 8.30

You've already asked this question several times. As I already told you the best you can do is to use Firebase Push notifications exactly as explained in the tutorial. Any other solution will be less reliable. If you have any new question then please start a new thread.

I repeat: I have activated push notifications with firebase, in huawai P8 they do not work! I have 6 devices in which they are active, they work in all 6 devices except in huawei!

Yes. Many times. As you have already been told, assuming that you implemented push notifications correctly, then there is nothing that you can do about it. You can try to whitelist the app in your device settings.

The whole point of push notifications is that the process doesn't need to run for your app to receive messages. See the video tutorial.

Erel, are you sure about this? I tried (very simple test, using your code, except the app name) and if I stop my app by settings and send a FCM message (I used your b4j example to do this) the app does not starts.
