Spent 10+ builds chasing a __init_tcb+4 / pthread_create SIGSEGV after adding the oboe audio backend. Every "fix" made things worse. Reverting all Android-specific files to the state at35642d1(build #6), which was the last commit where the Tauri Android app actually launched, rendered the home screen, and successfully registered on a relay. Reverted files (all back to their35642d1content): - desktop/src-tauri/Cargo.toml (no build-dep cc, no tracing-android) - desktop/src-tauri/build.rs (git hash only, no Oboe / cc build) - desktop/src-tauri/src/lib.rs (engine cfg-gated on non-android) - desktop/src-tauri/src/main.rs (two-line desktop entry) - desktop/src-tauri/src/engine.rs (desktop-only audio setup) - scripts/Dockerfile.android-builder (no android24→26 clang shim) - scripts/build-tauri-android.sh (no linker env vars / manifest patch) Deleted (were added betweenb314138ande2e023d): - desktop/src-tauri/cpp/getauxval_fix.c - desktop/src-tauri/cpp/oboe_bridge.{h,cpp} - desktop/src-tauri/cpp/oboe_stub.cpp - desktop/src-tauri/src/oboe_audio.rs Next: rebuild image on remote (to drop the baked-in clang shim), build an APK, install on Pixel 6, verify the UI renders the same way build #6 did. From there we add features back ONE at a time so we can actually bisect which one triggers the tao::ndk_glue crash. User's rule: "if you want to change stack, change incrementally, so we can debug".
