Android Question Not receive push when app is closed

[uniplan]

Hi, i have implemented the notification push with firebase, and i save and display my notify message in method "fm_MessageArrived" like this

...    n.SetInfo2(titolo,messaggio_problema,id_notifica,Main)

    n.Vibrate=True
    n.AutoCancel=True
    n.Notify(id_notifica)

i set the actovity main to start when the notify is clicked.
But i have a problem when i start phone and app is closed...i don't receive the notifications.
Only when i start the application, i receive the notify.
Ho i can solve it and receive the notify always?

Thank you

What is targetsdk is set to?
How are you sending the Push? With the B4J Code or with the FB console?

Please note the infos here:
https://www.b4x.com/android/forum/threads/android-jar-targetsdkversion-minsdkversion.87610/

Especially

- 26 - background limits. Will require an update to B4A. Don't set targetSdkVersion to 26 if you are using features such as: push notifications, StartServiceAt or #StartAtBoot.

android:minSdkVersion="7" android:targetSdkVersion="22"

thi is my configuration...
and the firebase service is set with #StartAtBoot: false
i send push with window service , i create a json and send post message.
what i can do for my b4a App?

 

[DonManfred]

i send push with window service , i create a json and send post message.

Make sure to use the correct json format to send. Check the B4J App in the Tutorial.

Yes because i receive correctly the push when app is opened or work in background.If is closed i don't receive it.

All i can say is:

Check the B4J App and the results. (I´m pretty sure it does work.)
If it works than the json format you are sending is wrong and you need to adapt it to be the same format as the B4J App is sending.
