android.database.CursorWindowAllocationException: Cursor window allocation of 2048 kb failed.

The result of the database-query is more than 2mb of data. 2mb is the limit of sqlite for one query.

The result of the database-query is more than 2mb of data. 2mb is the limit of sqlite for one query.

I fixed it with changing the public sub listkeys of datastore module to

Public Sub ListKeys As List
    Dim c As Cursor
    c = sql1.ExecQuery("SELECT key FROM main")
    Dim res As List
    res.Initialize
    For row = 0 To c.RowCount - 1
        c.Position = row
        res.Add(c.GetString2(0))
    Next
    c.Close
    Return res
   
End Sub

added a c.close.
