Phyjnius is a fork of the kivy/pyjnius project. Phyjnius provides a Java-Python bridge to access Java class as Python class, using JNI and Java reflection. Phyjnius aims to provide a "Pythonic" Java-Python bridge that allows Python developers to use Java libraries efficiently and comfortably.

PhyJNIus is used by the ovation package, a Python API for the Ovation Scientific Data Management System.

>>> from jnius import autoclass
>>> autoclass('java.lang.System').out.println('Hello world')
Hello world

>>> Stack = autoclass('java.util.Stack')
>>> stack = Stack()
>>> stack.push('hello')
>>> stack.push('world')
>>> print stack.pop()
world
>>> print stack.pop()
hello

You need a java JDK installed (openjdk will do), cython, and make to build it

make

That's it! you can run the tests with

make tests

To make sure everything is running right.

When you use autoclass, it will discover all the methods and fields within the object, and resolve it. For now, it can be better to declare and use only what you need. The previous example can be done manually:

from time import sleep
from java import MetaJavaClass, JavaClass, JavaMethod, JavaStaticMethod

class Hardware(JavaClass):
    __metaclass__ = MetaJavaClass
    __javaclass__ = 'org/renpy/android/Hardware'
    vibrate = JavaStaticMethod('(D)V')
    accelerometerEnable = JavaStaticMethod('(Z)V')
    accelerometerReading = JavaStaticMethod('()[F')
    getDPI = JavaStaticMethod('()I')
    
# use that new class!
print 'DPI is', Hardware.getDPI()

Hardware.accelerometerEnable()
for x in xrange(20):
    print Hardware.accelerometerReading()
    sleep(.1)
