error when I try to run titanium app on android emulator

Question

I have build an app in titanium studio and I have runned it both on iphone simulator and iphone device and it works perfectly. But when I try to run it on android emulator or android device it crashes.

I get the following error:

Has anyone any idea about what is wrong? I would post some code, but is too long and I don't know which part causes this problem.

Wait for your answers, thank you!

Answer 1

// this sets the background color of the master UIView (when there are no windows/tab groups on it)


//Ti.include('Window1.js');
Titanium.UI.setBackgroundColor('#000');

// create tab group


var placeHolders = [{left:10, top:10, width:20, height:20, bgColor:"#FFF", bgAlpha:0.5, img:""},
                    {left:30, top:20, width:50, height:50, bgColor:Math.random * 0xFFFFFF, bgAlpha:0.5, img:""},
                    {left:60, top:60, width:20, height:20, bgColor:Math.random * 0xFFFFFF, bgAlpha:0.5, img:""},
                    {left:100, top:20, width:20, height:20, bgColor:Math.random * 0xFFFFFF, bgAlpha:0.5, img:""},
                    {left:50, top:100, width:20, height:20, bgColor:Math.random * 0xFFFFFF, bgAlpha:0.5, img:""}
                    ];


var tabGroup = Titanium.UI.createTabGroup();





var parentWindow = Titanium.UI.createWindow({  
    title:'Tab 1',
    backgroundImage:"assets/background.png",
    backgroundColor:'#fff',
    navBarHidden:true,
    tabBarHidden:true
});
addPlaceHolders();

function addPlaceHolders()
{
    for(i = 0; i < placeHolders.length; i++)
    {
        var placeHolder = placeHolders[i];
        var placeHolderView = Titanium.UI.createView({
            top:placeHolder.top,
            left:placeHolder.left,
            height:placeHolder.height,
            width:placeHolder.width,
            backgroundColor:placeHolder.bgColor,
            opacity:placeHolder.bgAlpha

        });
        placeHolderView.name = i;
        parentWindow.add(placeHolderView);
        placeHolderView.addEventListener("click", onPlaceHolderClick);
    }
}


var main = Titanium.UI.createTab({  
    title:'Tab 1',
    window:parentWindow
});
//  add tabs
tabGroup.addTab(main);  

// open tab group
tabGroup.open();

function onPlaceHolderClick(e)
{
    //tell me wot to do here
    alert("tell me wo to do here");
}
