Barnes & Noble released its reader app for Android this week. It is called Nook for Android and part of the bookseller’s rebranding of its eReader line-up of products. With the new Android Nook app, you can read e-books purchased through the B&N online bookstore. Existing apps on other platforms (iPad, BlackBerry, iPhone) are also being renamed to reflect the Nook brand. All of the apps will sync content and bookmarks from the B&N online bookshelf, enabling the ability to use multiple devices (including the Nook electronic reader) for reading e-books. With these changes, Nook finally is on par with Amazon’s (a AMZN) Kindle line-up of apps and devices.

Google recently announced the App Inventor, a simple graphical online tool for producing home-brew Android apps. The budding app programmer positions building blocks on the screen and assigns simple programming tasks to them to design Android apps for personal use. Kevin Tofel took App Inventor for a spin and found it to be a good educational tool to ease into programming for the Android platform.
