B4J Code Snippet Range function

This may be useful.
This little method allows you to specify a range for 'For Each' loops etc, or set an array to a range of values.
B4X:
Sub AppStart (Args() As String)
    
    Dim a() As Int = range(-4,4)
    
    For Each item As Object In a
        Log(item)
    Next
    
    For Each number In range(10,-9)
        Log(number)
    Next
End Sub

Sub range(s As Int,e As Int) As Int()
    Dim ret(IIf(s < e ,e - s + 1,s - e + 1)) As Int
    Dim count As Int

    For a = s To e Step IIf(s<e,1,-1)
        ret(count) = a
        count = count + 1
    Next

    Return ret
End Sub
