Last night I did a deep dive webinar on Edge Animate at Adobe TechLive (you will be able to watch it here soon). During the session I covered how you can animate HTML elements over a curved motion path. I haven’t found a really good explanation of this topic in other places so I thought I would record my approach to it and share it with others!

Winter sports season has begun for good (at least in my region ;)) and I thought it would be nice to see how Edge Animate can help us express our hobbies. So what you see below was entirely built with HTML5/JavaScript using Animate and Illustrator 😉 If you want to learn how to do it yourself please join my “HTML Animation with Edge Animate” online session during the Create the Web live event next Tuesday (January 15, 2013 @ 1:00 PM EST – 4:00 PM EST).

The Create The Web online event is part of new initiative from the Adobe Evangelism team called Adobe Tech Live. The event is a replay of a world wide tour that was held by Adobe at the end of 2012. So if you missed it nearby, please join us on January 15:

Creating End Of The World Timer with Edge Animate

Attend today’s Create The Web online sessions and learn how to create your own end of the world timer with Adobe Edge Animate. There is not much time left. The Edge Animate webinar starts at 19:30 CET and the end of the world is tomorrow at 10:11 CET 😉

By the way, today’s online event is the first one under the umbrella of our new initiative called Adobe TechLive. In the future, our Evangelism team is planning to use this new channel to host online webinars like this one, in-depth online workshops, interactive chats with Adobe Product Managers and I guess potentially anyone that would like to share valuable content around the web technologies.

UPDATE (2012-12-21): I guess end of the world didn’t happen so in this case it really makes sense to learn Edge Animate, you can watch my session at the 31:45 minute mark here.

Native scrolling in jQuery Mobile/PhoneGap applications

In one of my previous blog posts I covered how to fix flickers and jumps during page transitions when using jQuery Mobile with PhoneGap. The good news is that flickers were eliminated with latest release of PhoneGap 2.1 and its departure from using IFrame for JavaScript to Native bridge. Unfortunately issue of 1px jumps is still there, but that is by design in jQuery Mobile. So this means my solution with additional div element hosting application content is still valid.

Embedding CordovaLib in your iOS/PhoneGap app project

As you may already know PhoneGap/Cordova 2.x has changed how the framework is referenced in iOS projects. This new approach gives more flexibility and ease of installation but at the same time it has some quirks especially when working in Xcode on multiple projects at the same time. This may actually change in the future releases as you may see there is an active discussion about it on the callback-dev mailing list.

In the meantime I wanted to share how you can quickly change a reference to CordovaLib directly from Xcode. The approach I prefer is to embed CordovaLib under my project directory. This way I can push it to my repository and version control it with my project files.

PhoneGap 2.0 – Getting Started

As you may already know PhoneGap 2.0 was released last Friday. This is a major release that brings some new features and lots of changes around the way you create and setup your development environment. For example to create a new iOS/PhoneGap project you don’t use a wizard from Xcode anymore; now you need to launch a bash script from command line. Below you will find two short video tutorials that demonstrate how to get started for both Android and iOS platforms. Also after the videos you can find some additional steps that I had to go through in order to get everything running properly. I know these steps may not be necessary for all. I’ve tested it also on my colleague’s less polluted Mac and everything worked out of the box 😉

Fixing flickers & jumps of jQuery Mobile transitions in PhoneGap apps

Recently I have been working on a mobile app that uses jQuery Mobile 1.1.0 as a UI framework. In general I’ve had really good experience with jQuery Mobile except it gave me some headaches when it came to page transitions. Some really weird flickers and jumps started to popup when I deployed it on the iOS 5.x platform as a PhoneGap app. This was something I didn’t experience when the same code was running in a device browser. After a few hours of digging into the issue I came up with a workaround that I didn’t find anywhere else and that solved all my problems :) I actually have seen all kinds of fixes to similar issues but I think this one is least invasive, because it doesn’t involve any framework code tweaks.

HTML5 for App Developers: PhoneGap Build

Below you can find a short video tutorial on how to quickly get up and running with the PhoneGap Build service. PhoneGap Build allows you to compile and package your PhoneGap/Cordova apps for different platforms using an online service. This is especially useful when you are doing iOS development and you don’t have access to a Mac machine and Xcode. The same thing also applies if you would want to publish your app to Windows Phone devices and you are not a PC gal or guy 😉

JavaScript Prototypal inheritance for class’ical developers

Developers who are learning JavaScript and have prior experience with strongly typed classical languages like Java, C#, or C++ often have trouble using the JavaScript inheritance model. Some even think that JavaScript doesn’t support inheritance at least that’s what I thought when I first learned it. Well, I was completely wrong!
