App Inventor for Android is a development environment allowing non-programmers to create their own applications for devices using Google's Android operating system. Tools are provided for creating many kinds of applications, but it is currently difficult to create interactive musical apps. I chose to address this issue by adding a component that would enable users to include limited real-time sound synthesis in their apps. Specifically, I designed an interface for playing notes by specifying pitch, volume and duration. I also added controls for adding reverb, envelopes and changing instruments. To support my component, I devised a system for managing libraries and assets, which allows native code to be packaged with an app, and ensures that any additional files are loaded only if necessary. This paper will discuss the motivation for my changes, the process of their design and the benefits they should provide to users and developers.
