build Android arm64-v8a wheel

[rishavsanjay]

Adds an Android arm64-v8a build for libtinymesa.so.

• Android API 25, NDK r29, Mesa 25.2.7
• builds only the NIR + IR3/freedreno path needed for Adreno

NAK and libtinymesa_cpu.so are omitted to keep the Android build simple and avoid cross-compiling LLVM (its very annoying).

This keeps the Android wheel focused on the Adreno use case for now; broader compiler/CPU support can be added separately if needed.

my bad, for some reason gh didnt trigger actions on this branch on my fork? run succeeded on an another branch tho.

verified the Android arm64-v8a wheel on my phone, tinymesa imports successfully and IR3 also works. Screenshot attached.

there is another problem though
Termux builds its Python package for Android API 24, while Mesa 25.2.7 requires API 25. This means that pip install tinymesa is rejected on standard Termux, even if device is API 25>= .

The workaround is to explicitly install for android_25_arm64_v8a using --platform. it's not too bad, but still annoying, and there doesn’t seem to be a clean fix without lowering Mesa’s API or using a Python package built for API 25+.

Neat. Does it work just as a compiler in tinygrad (ie. DEV=NULL:IR3:a630)?

As for the the API version thing, if it requires significant patches to mesa to use version 24 it's probably fine to require pip install --platform (should mention that in README though).
