Android Question Permanent notifications sometimes appear

[Alankoba]

Migrating from API 26 to 29 I noticed strange behavior in my app.
No reason a notification appears permanently (cannot be deleted)
I use Firebase notifications, but no messages have been sent to the app.


My FirebaseMessaging.b4a

Sub Process_Globals
    Public fm As FirebaseMessaging
End Sub

Sub Service_Create
    fm.Initialize("fm")
End Sub

Public Sub SubscribeToTopics
    fm.SubscribeToTopic("pedidoacaigoods_android_main")
    Log(fm.token)
End Sub

Sub Service_Start (StartingIntent As Intent)
    If StartingIntent.IsInitialized And fm.HandleIntent(StartingIntent) Then Return
End Sub

Sub fm_MessageArrived (Message As RemoteMessage)
    Log("Message arrived")
    Log($"Message data: ${Message.GetData}"$)
    CallSub3(Main, "msgPush", Message.GetData.Get("title"), Message.GetData.Get("body"))
End Sub

Sub called in fm_MessageArrived

Sub msgPush(titulo As String, msg As String)
    Msgbox(msg, titulo)
End Sub

My Manifest

AddManifestText(
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="29"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)
    
AddApplicationText(
 
<uses-library
      android:name="org.apache.http.legacy"
      android:required="false" />)
    

SetActivityAttribute (Main, android:exported, "true")
SetActivityAttribute (Main, android:taskAffinity, "")
SetActivityAttribute (Main, android:theme, "@android:style/Theme.DeviceDefault.Light")   

SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
SetApplicationAttribute(android:theme, "@android:style/Theme.Holo")
' fix api 29
SetApplicationAttribute(android:usesCleartextTraffic,"true")
'End of default text.

Sub Service_Start (StartingIntent As Intent)
    Service.StopAutomaticForeground 'Starter service can start in the foreground state in some edge cases.
End Sub

Automatic Foreground Mode

 

[Alankoba]

On Samsung Galaxy smartphones (S8, S9, S10 With ONE UI) the problem still occurs even after the inclusion of the Service.StopAutomaticForeground line.

B4A Version 9.01.2

Is it a bug?

 

[Erel]

Please post the updated code.

 

[Alankoba]

Sub Process_Globals
    Public fm As FirebaseMessaging
End Sub

Sub Service_Create
    fm.Initialize("fm")
End Sub

Public Sub SubscribeToTopics
    fm.SubscribeToTopic("pedidoacaigoods_android_main")
    Log(fm.token)
End Sub

Sub Service_Start (StartingIntent As Intent)
    If StartingIntent.IsInitialized Then fm.HandleIntent(StartingIntent)
    Sleep(0)
    Service.StopAutomaticForeground 'remove if not using B4A v8+.  
End Sub

Sub fm_MessageArrived (Message As RemoteMessage)
    Log("Message arrived")
    Log($"Message data: ${Message.GetData}"$)
    CallSub3(Main, "msgPush", Message.GetData.Get("title"), Message.GetData.Get("body"))
End Sub

----

Sub msgPush(titulo As String, msg As String)
    Msgbox(msg, titulo)
End Sub

Code looks correct. You can remove the Sleep(0) it is not needed. Are there any other services in your program?

Why have you added these lines:

SetActivityAttribute (Main, android:exported, "true")
SetActivityAttribute (Main, android:taskAffinity, "")

 

[Alankoba]

There are no other services.

The lines you quoted are from a lib I no longer use, I will remove them.

Barx library

[Erel]

The updated code you posted will not show the automatic foreground notification. The previous code will show. Maybe you are still running an old version of your app.

 

[Alankoba]

Yes, with the fix the problem stopped, but in the Samsung Galaxy continued to happen.

I removed the lines from the manifest and I will test again ...


Is it possible to test without waiting at random mode?

 

[Alankoba]

The problem continues after removing the lines from the manifest. On Samsung Galaxy smartphones with Android 9.
B4A Updated (9.50 BETA 1)

 

[Erel]

Can you upload the project?

I don't know whether this is the cause of the problem however the starter service should never be explicitly started. This means that StartAtBoot must be False:

 

[Alankoba]

In Starter.bas I made the following change:

Sub Service_Start (StartingIntent As Intent)
    Service.StopAutomaticForeground 'Starter service can start in the foreground state in some edge cases.
End Sub

It seems that the problem has been solved! But turning on the device, receiving a push notification and clicking it has no effect!

Clicking the notification only opens the app when the app has been manually opened at least once.

Clicking the notification only opens the app when the app has been manually opened at least once.

You should start a new thread for a new question. Make sure to disable StartAtBoot.
