Installation

PyJNIus has pre-compiled binaries on PyPi for recent Python versions on Linux, macOS and Windows.

On each platform:

pip install pyjnius

should successfully install the package.

If there is no pre-compiled binary available, pip install will aim to compile a binary on your operating system. For more information see the Building PyJNIus documentation.

You will need the Java JDK installed (OpenJDK is fine). PyJNIus searches for Java in the usual places on each operating system. If PyJNIus cannot find Java, set the JAVA_HOME environment variable (this is often needed on Windows).

Installation for Android

To use pyjnius in an Android app, you must include it in your compiled Python distribution. This is done automatically if you build a Kivy app, but you can also add it to your requirements explicitly as follows.

If you use buildozer, add pyjnius to your requirements in buildozer.spec:

requirements = pyjnius

If you use python-for-android directly, add pyjnius to the requirements argument when creating a dist or apk:

p4a apk --requirements=pyjnius

Installation for Conda

Similar to PIP there is a package manager for Anaconda <https://www.anaconda.com/what-is-anaconda/> called Conda. An unofficial compiled distributions of PyJNIus for Conda supported platforms you can find at https://anaconda.org/conda-forge/pyjnius.

You can install pyjnius with this command:

conda install -c conda-forge pyjnius

Or if you want a specific package label e.g. gcc7:

conda install -c conda-forge/label/gcc7 pyjnius
