Rubicon Java


This project has been archived. It was used by Briefcase 0.3.9 and earlier to support Android projects; however, that role is now performed by Chaquopy.

Rubicon Java is a bridge between the Java Runtime Environment and Python. It enables you to:

  • Instantiate objects defined in Java,

  • Invoke static and instance methods on objects defined in Java,

  • Access and modify static and instance fields on objects defined in Java, and

  • Write and use Python implementations of interfaces defined in Java.

It also includes wrappers of the some key data types from the Java standard library (e.g., java.lang.String).
