Java Bridge Programming

The App Inventor Java Bridge Library is a Java code library for building Android apps. It is easier to learn than the Android SDK and it uses the same terminology as App Inventor-- there is a Java class for every component. You can use this library in Android Studio to manually code Android apps. This page provides some lessons and tutorials for doing that. Download the library.
