Hi,

I'm currently getting an app crash on Android when refreshing a list content.

Currently I'm trying to dispose of the list and all assets entirely on a PanelScreen transition out complete listener, by calling clearList(), and recreating it on transition in start with createList().

Could you look at how I am currently handling the creation and disposal of a Feathers list and let me know if there is a better/correct way to do this.

public function createList():void {
if (_list) {
clearList();
}

for(var i:int = 0; i < imageDataArray.length; i++) {
_items.push(new GalleryListItem());
}
			
_list = new List();					
_list.itemRendererFactory = function():IListItemRenderer {
_renderer = new DragDropItemRenderer();				
_renderer.isLongPressEnabled = true;
return _renderer;
};
								
_vl = new VerticalLayout();
_vl.hasVariableItemDimensions = true;
_vl.useVirtualLayout = false;
_list.layout = _vl;						

_list.snapScrollPositionsToPixels = true;
_list.itemRendererProperties.hasLabelTextRenderer = false;
_list.verticalScrollPolicy = feathers.controls.ScrollPolicy.ON;
_list.horizontalScrollPolicy = feathers.controls.ScrollPolicy.OFF;
_list.scrollBarDisplayMode = feathers.controls.ScrollBarDisplayMode.FLOAT;				
_list.verticalMouseWheelScrollDirection = "vertical";
_list.verticalMouseWheelScrollStep = 50;
				
_list.topPullView = _pullView;
_list.addEventListener(starling.events.Event.UPDATE, list_updateHandler);
_pullView.addEventListener(FeathersEventType.PULLING, pullView_pullingHandler);
_list.verticalScrollBarFactory = myScrollBarFactoryFunction;
_list.isSelectable = true;
_list.hasElasticEdges = true;
_list.itemRendererProperties.width = 600;
_list.itemRendererProperties.height = 600;			
_list.addEventListener(TouchEvent.TOUCH, isTouched);
_list.addEventListener(FeathersEventType.RENDERER_ADD, rendererAdded);
_list.addEventListener(FeathersEventType.RENDERER_REMOVE, rendererRemoved);
_list.addEventListener(starling.events.Event.CHANGE, list_changeHandler);
_list.width = FullScreenExtension.screenWidth;
_list.height = FullScreenExtension.screenHeight - (Main.HEADER_HEIGHT + 80);
_list.y = 80;
addChildAt(_list,1);				
createListCollection();				
}


private function createListCollection():void {
if (_listCollection) {
_list.dataProvider = null;
_listCollection = null;
}

_listCollection = new ListCollection(_items);
_list.dataProvider = _listCollection;
}


private function clearList():void {
try{
_list.removeEventListener(starling.events.Event.UPDATE, list_updateHandler);
_pullView.removeEventListener(FeathersEventType.PULLING, pullView_pullingHandler);
_list.removeEventListener(FeathersEventType.RENDERER_ADD, rendererAdded);
_list.removeEventListener(FeathersEventType.RENDERER_REMOVE, rendererRemoved);
} catch (e:Error) {
}
					
try{
removeChild(_list);
} catch (e:Error) {
}

try{
_vl = null;
_renderer = null;
} catch (e:Error) {				
}
	
try{
if (_items) {
for(var i:int = _items.length; i > -1; i--) {						
_items.pop();		
}
}	
} catch (e:Error) {				
}
			
try{
_items = null;
} catch (e:Error) {				
}
			
try{
_listCollection = null;
} catch (e:Error) {				
}
			
try{				
_list = null;
} catch (e:Error) {				
}
			
}


private function myScrollBarFactoryFunction():IScrollBar {
var scrollBar:SimpleScrollBar = new SimpleScrollBar();
 scrollBar.direction = "vertical";
var scrollBarGraphic:Image = new Image(Main.assets.getTexture("vertical-scroll-bar-thumb-skin"));
scrollBarGraphic.scale9Grid = new Rectangle( 5, 5, 16, 10 );			
scrollBar.thumbProperties.defaultSkin = scrollBarGraphic; 	  
scrollBar.thumbProperties.width = 8;
 scrollBar.thumbProperties.minHeight = 40;
scrollBar.width = 8;
return scrollBar;
}

Thanks, Mark

PS the 'code' formatting button seems to have disappeared!
