The Google App Inventor, which allowed people with little or no programming knowledge to builds apps for Android, was introduced in mid-2010, but shut down only a year later. After finding a new home at the Massachusetts Institute of Technology shortly thereafter, the MIT has now gone a step further and released the source code of the App Inventor. It will continue to develop it on an open source basis.
For those interested, the source code is now available at Google Code, though the MIT notes that they’re not accepting contributions right now, and the documentation is lacking as well – both should be remedied once its App Inventor server goes public. However, you’re free to branch the code to create your own version, and use the “App Inventor” name and the accompanying logo without having to worry about copyright issues. To differentiate its own offering, the official version will be called “MIT App Inventor” instead.
