What is Java Bridge?

The App Inventor Java Bridge is an exploratory (alpha) version of App Inventor that allows you to generate a Java equivalent of the apps you have built. The tool helps students who have learned coding in AI’s visual block-based paradigm to transition to coding in a textual programming language. Besides the educational benefits, the tool also allows for hybrid development whereby the visual blocks language is used to create a portion of the app, and Java is used to add functionality that is difficult to develop in AI.

Hybrid Development

Create the initial version of an app using App Inventor, then add functionality with Java

Clean Code Generation

Clean transition from visual blocks editor to textual java code.

Project Setup

The App Inventor Java Bridge provides you with the Java equivalent of any App Inventor project you create. It generates a .zip project file that you can import into Android Studio or Eclipse. Here are steps to make this easy.
