Hello!
I am trying to create my chat. I use for this Firebase.
on my Honor it works, on emulators with google_apis and google_apis_playstore it works to, but on default android emulator and my One plus it doesn't (i have google services).

I have no idea what the problem is, I will be glad for any help)

My subs

fm_MessageArrived:
Code: Copy 
Sub fm_MessageArrived (Message As RemoteMessage)
    Log("Message arrived")
    Log($"Message data: ${Message.GetData}"$)
    Dim n As Notification
    n.Initialize
    n.Icon = "icon"
    n.SetInfo(Message.GetData.Get("title"), Message.GetData.Get("body"), chatex)
    n.Notify(1)
  
    CallSub3(chatex,"writemessage",Message.GetData.Get("title"),Message.GetData.Get("body"))
End Sub

SendMessage:
Code: Copy 
Private Sub SendMessage(Topic As String, Title As String, Body As String)
    Log("MyTopic ------------> "& Topic)
    Dim Job As HttpJob
    Job.Initialize("fcm", Me)
    Dim m As Map = CreateMap("to": $"/topics/${Topic}"$)
    Dim data As Map = CreateMap("title": Title, "body": Body)
    m.Put("data", data)
    Dim jg As JSONGenerator
    jg.Initialize(m)
    Job.PostString("https://fcm.googleapis.com/fcm/send", jg.ToString)
    Job.GetRequest.SetContentType("application/json;charset=UTF-8")
    Job.GetRequest.SetHeader("Authorization", "key=" & WebApiKey)
End Sub

and my manifest file
Code: Copy 
AddManifestText(
<uses-sdk android:minSdkVersion="16" android:targetSdkVersion="23"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>
    )
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")

Is notification enabled on the real phone? If not - that's the reason, Check the phone settings. Also - check the app settings, check the app info in applications list (just tap on the app name in the list) and check App Notification if it's On or Off.

Don't waste your time with the emulator.

Code: Copy 
CallSub3(chatex,"writemessage",Message.GetData.Get("title"),Message.GetData.Get("body"))
What is chatex?

Make sure not to kill the app with a swipe and test it in release mode.

It will only work when a message arrives while the activity is in the foreground.

I checking on two phones at the same time, while my activity is in the foreground. From first (HONOR) I can send messages and see all messages (mine and from another phone), but from another one I can only send messages and dont see all messages (from HONOR and from another phone)
As i found out, sub fm_MessageArrived not called on second device

With newer Android versions came more possibilities to set options. Mostly there are config issues which cause messages to be not delivered like.

- energy savings
- app isn't allowed to run in the background = app is fully stopped when phone goes to sleep (older phones have a whitelist, on my Huawei P10 even WhatsApp wasn't allowed to run in the background first).
- app isn't allowed to show messages
- ...

If the phone is set up correctly, you can even swipe the app without problems.

Hint: Use DATA messages only. These do not throw a notification (= less problems due to settings). Throw a notification on you own.

Try this (with high priority) and send a timestamp inside the message to check if the message IS delivered or just the notification isn't "fired":



B4X: Copy 
Private Sub SendMessageToSingleDevice(Devtoken As String, MyData As String)
 
   Dim Job As HttpJob
   Job.Initialize("SendMessage", Me)
  
   Dim m As Map = CreateMap("to": $"${Devtoken}"$)
   Dim data As Map = CreateMap("data": MyData)
    [B][COLOR=rgb(209, 72, 65)]Dim pri As Map=CreateMap("priority":"high") 'important [/COLOR][/B]
    m.Put("data", data)
    m.Put("android", pri)
 
   Dim jg As JSONGenerator
   jg.Initialize(m)
   Job.Tag=jg
   Log(jg.ToString)
   Job.PostString("https://fcm.googleapis.com/fcm/send", jg.ToString)
   Job.GetRequest.SetContentType("application/json;charset=UTF-8")
   Job.GetRequest.SetHeader("Authorization", "key=" & API_KEY)
  
  End Sub

B4X: Copy 
Sub fm_MessageArrived (Message As RemoteMessage)
    
    Log("Message arrived")
    
    Dim n As Notification
   [B][COLOR=rgb(209, 72, 65)] n.Initialize2(n.IMPORTANCE_HIGH) 'important otherwise the notification isn't "fired"[/COLOR][/B]
    
    n.Icon = "icon"
    n.OnGoingEvent=False
    n.Light=True
    n.Vibrate=False
    n.SetInfo2("FCM","The message...","This is the tag", "Main")
    
    n.Notify(1)


Works for me
