preload

I searched everywhere for this but no one appears to have an answer. My simple question is: Is there a way to preload an activity? I need this because I use a tab,and a tab has multiple activities. One of my activities is a rss reader,and it loads pretty hard(about 2-3 seconds). All I found on the web is a joke.Everyone has an opinion,but no one can point you to a sample code. Waiting for an answer,thanks! This is the code that loads the feed: At onCreate: // go get our feed! feed = getFeed(RSSFEEDOFCHOICE); // display UI UpdateDisplay(); countdown(); And the functions: private RSSFeed getFeed

I have a website that plays sound when you click a button. This is how I do it function PlaySound(soundfile) { $('#soundContainer').html("<embed src='/uploads/sounds/" + soundfile + "' hidden=true autostart=true loop=false>"); } How do you preload the sound file beforehand?

In short, I want to do this: load configuration, then initialize the application using the loaded configuration. I created a custom preloader to help solve this. But as it turns out, the application's createChildren() method already gets called during preloading, when

I'm trying to preload image on click event: // new image object var imgObject = new Image(); // assign the path to the image to the src property imgObject.src = document.URL + 'image/image.jpg'; // check if image has loaded if (imgObject.complete) { But the complete call never returns true on the first click - any idea what I'm missing here? .complete is a property of the image object, not an event that you can attach to. Use the onload event: var image = new Image(); image.onload = function() { alert('image loaded'); }; image.src = document.URL + 'image/image.jpg'; Note: Be sure to attach to
