i have a large app that loads several large arrays, after loading 6 or 7 time i get this error: java.lang.OutOfMemoryError: Failed to allocate a 55308 byte allocation with 45840 free bytes and 44KB until OOM. How can i clear memory used each time i go to restart loading the arrays?
Thanks.

First Module
Dim a(300) As String
Dim b(300) As String
Dim c(300) As String
Dim d(300) As String
Second Module
Dim a(300) As String
Dim b(300) As String
Dim c(300) As String
Dim z(300) As String
Third Module
Dim a(200) As String

not all arrays are full at any time but the do reload 6-8 times before the error.

Sub parser_EndElement (Url As String, Name As String, Text As StringBuilder)

If Name="a" Then
n = n + 1
a(n) = Text
End If

If Name="t" Then
b(n) = Text
End If
If Name="s" Then z(n) = Text
If Name="f" Then c(n) = Text
'Log(a(n))
'Log(z(n))
m.Clear
End Sub

all arrays are loaded via xml file downloaded.
size varies from 5 items to 120 item per load.

xml file:
<?xml version="1.0" encoding="ISO-8859-1"?>
<menu>
<c>
<t></t>
<f></f>
<s>l</s>
<a></a>
</c>
</menu>

Please use code tags when posting code - available in the new forum from the right hand three vertical dots dropdown in the post editor.

Here is nothing obvious in that code and the array use appears quite modest so there is something in the overall structure of your code that is causing the overuse or retention of memory.

Downsampling image due to lack of memory.

ok, i have narrowed it down to the fact that i am also download an image to put in the list each time i renew the list.
i have turned off: 'CallSubDelayed2(ImageDownloader, "Download", m), and no errors.
is there a buffer i need to clear each time to release the memory?
thanks. Paul
