How to Reduce/Clear Android Heap Memory Size???

Hi All,

I use Titanium SDK 3.1.3.GA. When I run my app on the Android device the HEAP Memory not reduced. I cleared all the children’s after window closed. 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 if 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 and EXIT.

my TiApp.xml file:

<android xmlns:android="http://schemas.android.com/apk/res/android">
        <property name="ti.android.threadstacksize" type="int">41943040</property>

        </application>
 
    </android>

Is there any way to reduce heap memory, someone can help me…

Thanks
