當我嘗試在Android模擬器上運行鈦應用程序時出現錯誤

Question

我在鈦工作室中構建了一個應用程序，並且我在iphone模擬器和iphone設備上運行了它，並且它完美地工作。但是，當我嘗試在Android模擬器或Android設備上運行它時，它會崩潰。

我得到以下錯誤：

有沒有人什麼是錯的任何想法？我會發布一些代碼，但時間太長，我不知道哪個部分會導致此問題。

等你的答案，謝謝！

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"); 
}
