Lightweight window animation in Titanium for Android -

i'm trying follow guides window animation android in appcelerator titanium, none of them mentions lightweight vs heavyweight windows.

in case, simplest example doesn't work:

// in mainwindow do: var wininfoview = ti.ui.createwindow({  title : "info",  url : 'infoview.js',  // notice don't set window fullscreen or modal property window remains lightweight }); wininfoview.open({   animated : true }); 

neither more complicated one:

// in mainwindow do: var wininfoview = ti.ui.createwindow({  title : "info",  url : 'infoview.js',  // notice don't set window fullscreen or modal property window remains lightweight }); var slideleft = ti.ui.createanimation(); slideleft.left = 0; slideleft.duration = 300; wininfoview.open(slideleft); 

so, possible animate opening of lightweight window? how?

as explained @ docs : http://docs.appcelerator.com/titanium/latest/#!/api/titanium.ui.window

be sure had add code tiapp.xml, can using lightwindow in android platform

<property name="ti.android.uselegacywindow" type="bool">true</property> 

this code work me :

    var menuwindow = ti.ui.createwindow({                 top:0,                 left:0,                 width:150             });             menuwindow.open({                 activityenteranimation: ti.android.r.anim.slide_in_left             });  menuwindow.add(something);
