Android Question java.lang.NullPointerException: null receiver

[Declan]

I keep getting the following error.
This is strange as the code worked before, now suddenly throwing the error:
Error:

My Code:

Sub getHomeDevices
    Dim friendname As String
    
    clv1.Clear <-----------------------------------------Error Here
    DB.Initialize(DBFileDir, DBFileName, True)
    Dim Cursor1 As Cursor
    Cursor1 = DB.ExecQuery("SELECT * FROM trans ORDER BY id")
    For i = 0 To Cursor1.RowCount - 1
        Cursor1.Position = i
    
        Dim Transactions As Map
        Transactions.Initialize
        Transactions.Put(1, Cursor1.GetString("id"))
        Transactions.Put(2, Cursor1.GetString("deviceid"))
        Transactions.Put(3, Cursor1.GetString("lat"))
        Transactions.Put(4, Cursor1.GetString("lon"))
        Transactions.Put(5, Cursor1.GetString("volts"))
        Transactions.Put(6, Cursor1.GetString("msgid"))
        Transactions.Put(7, Cursor1.GetString("mysignal"))
        Transactions.Put(8, Cursor1.GetString("myspeed"))
        Transactions.Put(9, Cursor1.GetString("datetime"))
        Transactions.Put(10, Cursor1.GetString("fleet"))
        Transactions.Put(11, Cursor1.GetString("friendname"))
        
        Log(Transactions.Get(1))
        
        clv1.Add(CreateListItem(Transactions, clv1.AsView.Width, 80dip), friendname )
    Next

    Cursor1.Close
End Sub

I get this error in both Debug and Release modes.

Can you post the logs in release mode?

Can you post the logs in release mode?

Thanks - but for some strange reason it is sorted and I do not get the error.
I did nothing, but just started behaving itself

If you encounter such error again then try "clean project" - Ctrl + P.

Thank you
