RenPy sdkarm downloads regular RAPT which downloads x86_64 build_tools binaries

[DjBRINE]

While trying to build an Android universal APK of any of my projects in RenPy-sdkarm running on a prooted Ubuntu inside Termux on an Android tablet, I had stumbled upon a peculiar issue:

Ren'Py 8.2.3.24061702

I'm compiling a short test program, to see if you have a working JDK on your system.



Java version: 21
Target version: 21
OK




The JDK is present and working. Good!

Updating project.

Creating assets directory.

Packaging internal data.

I'm using Gradle to build the package.
To honour the JVM settings for this build a single-use Daemon process will be forked. For more on this, please refer to https://docs.gradle.org/8.5/userguide/gradle_daemon.html#sec:disabling_the_daemon in the Gradle documentation.
Daemon will be stopped at the end of the build

The build seems to have failed.

I tried to reinstall the Android SDK and RAPT multiple times
Tried different projects (The Question, freshly made dummy project, I Wani Hug That Gator)
Even tried nightly 8.3.0 builds with SDK 35
The error remains the same.
After many days of debugging I have discovered that RAPT provided me an Android SDK with build_tools (aapt2 in particular) compiled for x86_64 instead of aarch64

Expected result:
Successful build with arm RAPT Android SDK binaries in RenPy's sdkarm

Additional info:
Device: Xiaomi Pad 5
Termux: Latest F-Droid build
Ubuntu 24.04 LTS ARM
Kernel: Linux-6.2.1-PRoot-Distro
Aarch64 with glibc 2.39
RenPy version: 8.2.3.24061702 sdkarm
