Android Question IndexOutOfBoundsException

[mrumball]

I have the following code that throws an IndexOutOfBoundsException and i don't understand why

Dim c As Int = 0
        Log(PartToPick)
        Dim test1 As Int = parttopick.Size
        Log("parttopicksize = " & PartToPick.Size)
       
        For  c = 0 To PartToPick.Size -1
        Dim i As String = PartToPick.Get(c)

Error log with the array list items is below

I have worked this one out - i was removing items from the list - therefore the list was no longer the size it was at the start
