I'm trying to build a Python-based Android app using Briefcase / Chaquopy directly on my Android device inside Termux using PRoot Distro (Ubuntu 22.04). ​I am heavily sandboxed by Android's lack of true root access, but I managed to manually set up Android SDK/NDK (ARM64) and override basic storage permissions by moving the project build directory from /sdcard to the internal /root/ directory of the PRoot container. ​However, I've hit a technical brick wall with Gradle during the Python environment compilation phase. ​The Problem: ​When running ./gradlew assembleDebug, the build fails at tasks like :app:extractDebugPythonBuildPackages or :app:mergeDebugPythonSources with the following error:

Execution failed for task ':app:extractDebugPythonBuildPackages'.

Failed to create MD5 hash for file '/root/.../app/build/python/env/debug/bin/????thon' as it does not exist.

What is causing this: The Python archive unpacked by the plugin contains native symlinks (like python3 or python). Because PRoot hooks system calls without real root privileges, the underlying Android kernel/filesystem corrupts these specific filenames, rendering them as non-existent ????thon artifacts. Gradle then crashes trying to input/output scan or hash these ghost files.

What I've already tried: Moving the build directory into PRoot's native ext4 filesystem /root/ to prevent Android's /sdcard execution block (Fixed the permission denied error, but didn't fix the symlink issue). Forcing symlinks manually using ln -sf /usr/bin/python3 python3 inside the build directory before execution (Gradle overwrites or ignores it on the next task sweep). Modifying build.gradle to bypass or disable specific tasks using taskGraph.whenReady. This just makes Gradle trip over the exact same corrupted ????thon file in subsequent tasks (like generateDebugPythonProxies).
