This bundle really teaches you everything you need to know about developing for Android. And if you are already a developer, it's a good bundle to pick up and add even more things to your resume. Which can help you either get a raise at your current job or get a new higher-paying job. Which everyone loves getting bigger paychecks, right? Especially if you are only investing $29 and some extra time. Typically the Professional Android Developer Bundle would cost you $1475, but you can pick it up for a whopping 98% off of its regular price. But that's only through May 11th, so you'll want to pick it up soon!
