[AC-1559] How to Reduce/Clear Android Heap Memory Size???

Hi, We created app for Sales&Inventory Management System. This app having more no of screens so we used Multiple Windows concepts. our app working perfectly But we have MEMORY issue. Whenever i open the new window the Memory size was increased After Closed window i clear all the children's components & put 'null'. Device HEAP Memory size is not reduced. I have used below functions for clear children’s: . . . windowClosed : function(){ Controller.prototype. deAllocate(win); }, deAllocate : function(win) { var length = win.children.length; for (var ctr = length-1; ctr >= 0; ct--) { var childView = view.children[ctr]; if (childView != undefined || childView != null) { Ti.API.info(‘deAllocate -> ‘ + childView); Controller.prototype.deAllocateChildView(childView); win.remove(childView); childView = null; } childView = null; } win.close(); win = null; }, deAllocateChildView : function(view){ var length = view.children.length; for (var ctr = length-1; ctr >= 0; ctr--) { var childView = view.children[ctr]; if (childView != undefined || childView != null) { Ti.API.info(‘deAllocateChildView -> ‘ + childView); Controller.prototype.deAllocateChildView(childView); view.remove(childView); childView = null; } childView = null; } view = null; }, . . . I checked with logcat all the UI components are removed. but heap memory size is not reduced. whenever i opened new window the heap memory size is increasing. Once its reached 48MB my app will through OUT OF MEMORY exception is coming and app EXIT we need to restart the app. my TiApp.xml file: http://schemas.android.com/apk/res/android"> 41943040 41943040 17 distribution true dp false true Is there any way to reduce heap memory, can you help me to fix this problem… Thanks
