Android Question Error: java.lang.object cannot be cast to b4xpagesmanager (KeyValueStore and B4XPages)

[asales]

I get this error in the line below in my Alarm module receiver in a B4XPage Project.

Dim horanot As Double

If B4XPages.MainPage.kvs.GetDefault("hour_1", "08:00").As(String).Length > 1 Then
  horanot = Starter.kvs.GetDefault("hour_1", "08:00").As(String).SubString2(0,2)
End If

Dim t As Long
t = FindNextTime(Array As Double(horanot,12,18))

It occours when I check if the hour is setting in the KeyValueStore to the scheduling alarm.

I initializated the KVS in the B4XMainPage.

Due this information from Erel:
"Don't try to access B4XPages from FirebaseMessaging service. B4XPages can only be created after the main activity was created."

I tried to initializated the KVS in the Starter and get this error:
java.lang.NullPointerException: Attempt to invoke virtual method 'android.database.Cursor anywheresoftware.b4a.sql.SQL.ExecQuery2(java.lang.String, java.lang.String[])' on a null object reference

It not happens in an Activity project.

How can I check the values setting the the KVS in the Alarm module in a B4XPages project?

You need to move kvs to the starter service.

You need to move kvs to the starter service.

I tried to initializated the KVS in the Starter and get this error:
java.lang.NullPointerException: Attempt to invoke virtual method 'android.database.Cursor anywheresoftware.b4a.sql.SQL.ExecQuery2(java.lang.String, java.lang.String[])' on a null object reference

It not happens in an Activity project.

So, I put a copy this code in the Alarm service (and in the Starter Service)

xui.SetDataFolder("kvs")
kvs.Initialize(xui.DefaultFolder, "kvs.dat")

and worked in my tests. It read from kvs when the Alarm service is started (and the Starter don't).
Could be a problem use in this way?

In this case I would have done something like:

If Starter.kvs.IsInitialized = False Then Starter.kvs.Initialize(...)
'now use Starter.kvs
