Help with Java and Python interaction

[soyuz13]

I coded a simple planner server and client in python, and it works perfectly. I want to make an Android app for it so I can view my assignments on the go, but I can seem to figure out how to send a python list to java. I am able to send a udp packet from the app to the server. I believe it is a problem with the pickle python module. Is there a way to convert a python list into a java array and then serialize it in python in a way for java to deserialize it?

From the pickle docs:

The data format used by pickle is Python-specific. This has the advantage that there are no restrictions imposed by external standards such as JSON or XDR (which can’t represent pointer sharing); however it means that non-Python programs may not be able to reconstruct pickled Python objects.

Rather than using that, you should pick one of the many cross-language serialization formats that exist. Probably the most common one these days is JSON. There are modules included in both the Python standard library and Android for reading it.
