Android Question Problem with the array

[stopa]

Hello,
I'm working with my GPS project. At the moment, it's only test without gps, I'm sending random values from microcontroller to my device via bluetooth. Receiving works good, but I would like to save all the values of received signal in the array, but I can't do this. Array is empty all the time and I receive communicate from logs: "ArrayIsOutOfBoundException". I can't fix this.

It's my code (condensed a bit):

Dim WspX() As Double
-----------
If Buffer.Length=5 Then
  If Odebrane.StartsWith(Chr(104)) Then
  If Odebrane.EndsWith(Chr(13)) Then
  Try
      k=k+1
      Suwak2=Odebrane.SubString2(1,4)
    Val3 = NumberFormat(Suwak2,3,0)
    Val4 = Val3/250 'it's double
   

    For i=0 To k
        WspX(i)=Val4
    Next
        Log(WspX(i))

    Xmin = Activity.Width/2
  Catch
  Log(LastException.Message)
  End Try
  End If
  End If

Maybe it's better way to do this, without an array, but I don't have idea.

Waiting for some tips.

Regards.

You don't seem to have given the array any dimension so it is zero length. You need to identify the size - Dim WspX(some value) - before you start to use it. If you do not know how big the array would need to be, I would suggest you replace it with a List since you can just keep adding to it as needed. A list is very easy to use - see http://www.b4x.com/android/help/collections.html#list

Hello,
I was trying before with List, but something was wrong. I woke up today and fixed the code, thank you for help
