PyJNIus

Python module to access Java class as Python class, using JNI.

(Work in progress.)

Quick overview

>>> 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

Usage with python-for-android

• Get http://github.com/kivy/python-for-android
• Compile a distribution with -m "pyjnius kivy"
• Then, you can do this kind of things:

from time import sleep
from jnius import autoclass

Hardware = autoclass('org.renpy.android.Hardware')
print 'DPI is', Hardware.getDPI()

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

It will output something like:
