Javascript Ti.Media.takeScreenshot-只有创建视图层次结构的原始线程才能接触其视图

我在尝试拍摄屏幕截图时出现此错误。我可以拍摄屏幕，但即使同时出现此错误

这是我的密码

sharebutton.addEventListener('click', function(e) {
    Ti.Media.takeScreenshot(function(event) {
        //scrollView.toImage();
        var filenameforscreenshot = "screenshot" + new Date().getDate()+".jpg";
        Ti.API.info('cam filename-' + filenameforscreenshot);
        var scrnImage = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, filenameforscreenshot);
        scrnImage.write(event.media);
        Ti.App.Properties.setString("screenshotcapture", scrnImage.nativePath);
    });
    var createnewWindow = require('ui/sharestay');
    new createnewWindow(my_id, '').open();
    win.close();
});

控制台中的错误

[ERROR] :  TiExceptionHandler: (main) [0,5081] - Message: Uncaught Error:  Only the original thread that created a view hierarchy can touch its views.
[ERROR] :  TiExceptionHandler: (main) [0,5081] - Source: ).open(),o.close()}),u.addEventListener("click",function(){Ti.Media.takeScreen
