Android build error with module chess - Module not found

[Scintsz]

When trying to build an Android version, there is a library error related to the chess module inside "00-chess-engine/python-packages/chess/". The build finishes and installs on Android but fails upon running with the following message:

"""
I'm sorry, but an uncaught exception occurred.

While running game code:
File "game/00-chess-engine/chess_displayable.rpy", line 213, in
ModuleNotFoundError: No module named 'chess'

File "game/00-chess-engine/chess_displayable.rpy", line 213, in
ModuleNotFoundError: No module named 'chess'

"""

For some reason, the folder is read correctly. I already tried inserting "import chess" in the build.py and android.py, but it seems that this is not enough.

The mobile emulation on renpy launcher works fine.

This is a known issue but unfortunately I don't have an Android device to debug this on and have only been using the renpy mobile emulator. I will circle back to this one if I can get my hands on an Android device.

Briefly tested on a friend's phone. You will be able to import chess if you move the chess module (game/00-chess-engine/python-packages/chess) directly under game/. However, the next problem is the path of stockfish (the chess AI). Not even sure if stockfish can be loaded correctly without renpy.file on Android per renpy/renpy#1226.

[RuolinZheng08]

@Scintsz If you need a quick hacky way of making this work, try putting everything from 00-chess-engine/ directly into the base game/ directory and getting rid of any references to 00-chess-engine/ in the code. This way Android should be less confused about the chess package path and stockfish binary path.

@RuolinZheng08, sorry for the delay, thank you for your time, with your orientation, I removed any trace of the "00-chess-engine" folder, and adjusted the variables to the new location in /game, now the game open on the Android, but still there is a problem with Stockfish, the log is below. The file "stockfish-10-armv7" is in the equivelent folder on Linux, but perheaps I missed some step?
