Titanium:UIWebView工作者不在Android上工作

我在UIWebView HTML页面中使用JavaScript Web worker技术来实现Titanium应用程序中的后台任务。它在iOS上工作正常但在Android上没有运气,我甚至无法弄清楚错误细节。这是脚本代码:

<script>

    function startWorker(){
    var worker = new Worker('/worker.js');
    // message event handler
    worker.onmessage = function (event) {
        // logging
        Ti.API.error( 'WebWorkerMessage:'+ JSON.stringify(event) );
        // update the html page - not actually needed, just for demostration should the WebView be visible
        document.getElementById('result').textContent = event.data;
        // fire a titanium app event

        Ti.App.fireEvent( "WORKER", { data: event.data } );


    };
    // error event handler
    worker.onerror = function(event){
        Ti.API.error( 'WebWorkerError:'+ JSON.stringify(event) );
    };  
    }
 </script>

一旦从我的Alloy控制器评估此脚本,就会调用错误处理程序。我正在Android 4.4.2设备上测试这个脚本,这个错误的日志是没用的:

WebWorkerError:{"cancelBubble":false,"returnValue":true,"srcElement":{},"defaultPrevented":false,"timeStamp":1422484158088,"cancelable":true,"bubbles":false,"eventPhase":2,"currentTarget":{},"target":{},"type":"error"}

有什么建议吗?
