In the questions I asked before (Here and here), I said that I got an error due to KVS. Then I completely removed KVS from my project. I am currently using firebasemessaging, which has no function, but still my program crashes after about 30 minutes (when I measured more carefully, I saw that it was about 30 minutes, not 10 minutes).

I am getting this error messages first but not crashing app

B4X: 
(SocketException) java.net.SocketException: Too many open files

After this error message (java.lang.RuntimeException: Adding window failed) and crashed

B4X:

My FirebaseMessaging code here

    #StartAtBoot: False
    
#End Region

Sub Process_Globals
    Private fm As FirebaseMessaging
    'Private KVS As KeyValueStore
    'Private xui As XUI 
End Sub

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

Public Sub SubscribeToTopics
    'fm.SubscribeToTopic("general") 'you can subscribe to more topics
End Sub

Sub Service_Start (StartingIntent As Intent)  
'    xui.SetDataFolder("kvs")
'    KVS.Initialize(xui.DefaultFolder, "kvs.dat")
'    If KVS.Get("BildirimlerAcik") <> Null Then
'        If KVS.Get("BildirimlerAcik") Then
'            If StartingIntent.IsInitialized Then fm.HandleIntent(StartingIntent)
'            Sleep(0)

'    Else
'        KVS.Put("BildirimlerAcik", True)

'    KVS.Close
End Sub

Sub fm_MessageArrived (Message As RemoteMessage)

    Dim n As Notification

The error has nothing to do with the code you posted.

Click to expand...
Posting the same question multiple times is the sure way not to get help. Especially when you haven't provided enough information in both posts.
I'm closing this thread as it too doesn't include enough information.
