how debug a memory error?

melamoud · Feb 10, 2013

trying to debug an out of memory I have, need some help with the tools avilable

I have a service that fetch xml pages from the internet one at a time , parse the results and put it in a db.

I maintain few lists that does not grow much, so it should not be the problem
I get out of memory after a whle (before the end of the scan)

in order to debug it I need at least
1. way to log amount of free memory on the phone
2. way to log amount of memory used by my process

any idea how to get that info ?

any other ideas of tools to help me narrow down the issue ?
thanks

Can you post the error message (stack trace) ?

is not always the same, and not always at the same time (as in most cases of memory issues) but here it is

and this is after app is sleeped for 12 hours (no activity on phone)
the images on the slide menu are small (5K) I have other pictures not related to slide menu that each can be 160K

Most memory issues are related to images. Can you post the code in SlideMenu.AddItem ?

sure here it is:

B4X:

Public Sub AddItem(Text As String, Image As Bitmap, ReturnValue As Object, tag As Int)
   Utilities.LogM(0,"Add Item has been called:" & Text & " tag=" & tag & " Value="& ReturnValue)
   Dim item As ActionItem
   item.Initialize
   item.Text = Text
   item.Image = Image
   item.Value = ReturnValue
   item.tag = tag
   
   If Not(Image.IsInitialized) Then
      If (showNoImageToLeft) Then
         mListView.AddTwoLines2(Text,"",item)
      Else
         mListView.AddTwoLinesAndBitmap2(Text, "", Null, item)      
      End If
   Else
      Utilities.LogM(0,"has image of h=" & Image.Height & " w=" & Image.Width)
      mListView.AddTwoLinesAndBitmap2(Text, "", Image, item)
      hasImage = True
   End If
   'Log (mListView.Size & " items Hight:" & (mListView.Size * itemHeight))
            
   'mSlidePanel.Height = mListView.Size * itemHeight - 2
   'If (mSlidePanel.Height > 100%y - mSlidePanel.Top) Then mSlidePanel.Height = 100%y - mSlidePanel.Top

   mSlidePanel.Height = mListView.Size * itemHeight - 2   
   If (mSlidePanel.Height > 100%y) Then mSlidePanel.Height = 100%y
   mSlidePanel.Top = 100%y-mSlidePanel.Height ' set to grow from the bottom      
   mListView.Height = mSlidePanel.Height 
   'log ("width=" & mlistView.Width)
   Dim c As Canvas
   c.Initialize(mListView)
   Dim w As Int = c.MeasureStringWidth(Text,mListView.TwoLinesAndBitmap.Label.Typeface,mListView.TwoLinesAndBitmap.Label.TextSize) + mListView.TwoLinesAndBitmap.Label.Left+ 10
   'Log ("w=" & w)
   If (w>100%x) Then w = 100%x
   If (w > mSlidePanel.Width ) Then ' if smaller no need to change, leave the width as the wider of all labels
      'Log ("setting width to be:" & w)
      mSlidePanel.Width = w
      mListView.Width = w      
   End If   
End Sub

thanks

and here is the issue again now with more details (were not there before)

Try to remove these lines:

B4X:

Dim c As Canvas
c.Initialize(mListView)

It is not efficient to create a new canvas each time. You should instead create a single global canvas and reuse it.

fair point, but can that cause it ?

Erel · Feb 17, 2013

Yes. Each time you initialize the canvas a bitmap is created for the target view.

melamoud · Feb 17, 2013

I only have 6 items in the menu and I init only when app is created

so how much more that 6 spare canvases shoudl take compare to the list and the images etc ? enoght to kill the app ?

Erel · Feb 17, 2013

Impossible to say. You should test it.

melamoud · Feb 17, 2013

on it, (but it takes time to reproduce)
I will let you know

melamoud · Feb 17, 2013

no its now happened again (one canvas), and I think I know how to reproduce it,

if I exit the app (back button) while it is working (httpJOB running inside a serivce)
and start the app again , as soon as I call that slide menu additem it gets out of memory

it also happened in the past without me exit the app, but maybe the phone did killed it or paused it.

any idea ?

melamoud · Feb 17, 2013

and now it happened before the slidemenu init method in the activity create sub

Erel · Feb 18, 2013

My second guess is that you are loading large images in your layout file. The designer doesn't use LoadBitmapSample to load images (might be changed in the future...). You should check the dimension of each image and make sure that it is not too large.

melamoud · Feb 18, 2013

It might be I have only one large image set as background so it will be large dimension

But why this is happening mainly (not only) when I exit the app and start it again fast (almost every time)

Erel · Feb 18, 2013

Make sure that the image is not larger than it needs to be.

It happens because the Garbage collector hasn't released the memory from the previous loaded layout.

melamoud · Feb 18, 2013

so what can I do ?

its set backgroud it will be at the size of the phone layout

Erel · Feb 18, 2013

Not sure that I understand the question. The image resolution should not be larger than the view that holds it. Otherwise you are wasting memory.

melamoud · Feb 18, 2013

Ic no its not bigger.

how debug a memory error?
