memory leak when pushView an popView
Hello to community!
I am having problems of memory leaks with an app I had build. After using it for 30-40 min it begin to go slow and slow.
The app show images as a catalog, but when I push and pop the views my memory rise a lot.
I think I am deleting all my oibjects setting them to to null and disposing all de bitmapdata that I use so I think that the problem should not be there.
I have 3 views in my app menuView.mxml,categoriesView.mxml and productsView.mxml.
My App begin in my pc (not in tablet) with TotalMemory: 47Mb and Private Memory : 88 MB
After pushing and poping the views for 5 times I get TotalMemory: 61Mb and Private Memory : 101 MB
Imagine if I do this for 20 times, all the app begin to go very slow in my Ipad or my Samsung Galaxy Tab.
Why is this happening? I have no idea how to solve this.
Thanks a lot!!
I put some code below.
Whe I am in menuView i use the following code to push the view from menuView to categoriesView
protected function button3_clickHandler(event:MouseEvent):void
{
if((FlexGlobals.topLevelApplication.getIdClienteServidorCompraActual()!=null)&&(FlexGlobals.topLevelApplication.getIdClienteServidorCompraActual()>0))
{
navigator.pushView(categoriesView);
}
}
Whe I am in categoriesView i use the following code to push the view from categoriesView to productsView. In this view i have 3 button for each category.
protected function buttonC1_clickHandler(event:MouseEvent):void
{
//Categoria general con todos
var ab:ArrayCollection = getIdAmbienteServidor();
cleanMemory();
navigator.pushView(productsView, null);
}
private function cleanMemory():void
{
result.splice(0);
result = null;
System.gc();
}
Whe I am in productsView I use the following code to pop(I USE PUSH INSTEAD OF POP DUE TO DIFFERENT OPTIONS I HAVE) the view from productsView to categoriesView .
protected function button1_clickHandler(event:MouseEvent):void
{
cleanMemory();
navigator.pushView(menuView);
}
private function cleanMemory():void
{
if(image1 != null)
{
image1.source = "";
if(image1.bitmapData != null)
{
image1.bitmapData.dispose();
}
}
if(image2 != null)
{
image2.source = "";
if(image2.bitmapData != null)
{
image2.bitmapData.dispose();
}
}
if(result != null)
{
result.splice(0);
result = null;
}
if(result1 != null)
{
result1.splice(0);
result1 = null;
}
if(result2 != null)
{
result2.splice(0);
result2 = null;
}
dbConnection = null;
object1 = null;
object2 = null;
dataToSave = null;
cGreyImageSmallAsset = null;
cRedImageSmallAsset.bitmapData.dispose();
cRedImageSmallAsset = null;
cOrangeImageAsset.bitmapData.dispose();
cOrangeImageAsset = null;
cGreenImageAsset.bitmapData.dispose();
cGreenImageAsset = null;
cPinkImageAsset.bitmapData.dispose();
cPinkImageAsset = null;
cBlueImageAsset.bitmapData.dispose();
cBlueImageAsset = null;
cGreyImageAsset.bitmapData.dispose();
cGreyImageAsset = null;
cRedImageAsset.bitmapData.dispose();
cRedImageAsset = null;
cGreenImageSmall = null;
cOrangeImageSmall = null;
cPinkImageSmall = null;
cBlueImageSmall = null;
cGreyImageSmall = null;
cRedImageSmall= null;
cGreenImage = null;
cPinkImage = null;
cBlueImage= null;
cGreyImage = null;
cRedImage= null;
cOrangeImage= null;
System.gc();
}
I load the images with.
private function setImages():void
{
//var width:Number = FlexGlobals.topLevelApplication.width;
if(object1!=null)
{
//var widthImage1:Number = (width/2)-80;
//image1.width = widthImage1;
panelLeft.visible = true;
buttonLeftMore.visible = true;
image1.source = "file://" + File.applicationStorageDirectory.nativePath + "/b"+object1.idArchivo+"_500.jpg";
setObject1MainTexts();
}
else
{
image1.source = "";
panelLeft.visible = false;
buttonLeftMore.visible = false;
}
if(object2!=null)
{
//var widthImage2:Number = (width/2)-80;
//image2.width = widthImage2;
panelRight.visible = true;
buttonRightMore.visible = true;
image2.source = "file://" + File.applicationStorageDirectory.nativePath + "/b"+object2.idArchivo+"_500.jpg";
setObject2MainTexts();
}
else
{
image2.source = "";
panelRight.visible = false;
buttonRightMore.visible = false;
}
}
Whe I am in categoriesView i use the following code to pop(I USE PUSH INSTEAD OF POP DUE TO DIFFERENT OPTIONS I HAVE) the view from categoriesView to menuView.
protected function button1_clickHandler(event:MouseEvent):void
{
cleanMemory();
navigator.pushView(menuView);
}

{
result.splice(0);
result = null;
System.gc();
}
