Thanks for the reply.
I know there's way to pack jar or java files in the apk with buildozer. But what I would like to achieve is to access the external java files.(let's say in sdcard or internal storage of android phone or tablet)
I got this need because I'm playing with an interesting android app called "Pydroid" on which I can run my kivy programs without spending a lot of time and effort building an apk. It's a convenient tool for my work.
It's sort of like kivy launcher, but much more flexible. (It's not advertisement. I have NO any relationship with its developer.)
The problem I'm facing is some android python package come with java files(for example an android python package for Bluetooth Low Energy functions).
I can build this kind of android python package into an apk with buildozer. And it works well. But when it comes to "Pydroid", the pyjnius autoclass can not find the java class because the java files are not in a location it can search for.
I hope this explains my needs and problems better.
