Android Question Turn Bluetooth On SDK 33+ error

[Scantech]

Why is this error occuring. Works good with Erels Bluetooth Chat Example but not my project? How I get it going for Activity?

Private Sub StartActivityForResult(i As Intent)

    Dim jo As JavaObject = GetBA

    ion = jo.CreateEvent("anywheresoftware.b4a.IOnActivityResult", "ion", Null)

    jo.RunMethod("startActivityForResult", Array As Object(ion, i))

End Sub



Sub GetBA As Object

    Dim jo As JavaObject = Me

    Return jo.RunMethod("getBA", Null)

End Sub

Found the problem.

Use this for Activity and not B4xPages

Sub GetBA As Object
   Dim jo As JavaObject
   Dim cls As String = Me
   cls = cls.SubString("class ".Length)
   jo.InitializeStatic(cls)
   Return jo.GetField("processBA")
End Sub

It worked for me too. Thank you for sharing.
