# Standalone armeabi-v7a tracing agent for the native ARM32 investigation
# (see ARM64_TRANSLATION_LAYER.md's "Native ARM32 tracing harness" plan).
# Deliberately NOT wired into the main Gradle build (settings.gradle.kts) -
# this is a diagnostic-only artifact built and pushed to the device
# independently via build.sh, never bundled into any APK. Runs exclusively
# on the "native32" flavor's real, unmodified libapp.so on the Galaxy A9.

# Deliberately NOT linking against libGLESv2.so here, even though the GLES
# wrappers exist below - confirmed live on-device that an eager DT_NEEDED
# dependency on it crashes the WHOLE process immediately on launch (exit
# code 1, right after Zygote's early "-Xcheck:jni" specialization, well
# before any Activity/EGL/GL context exists to make libGLESv2.so resolvable
# that early). Each GLES wrapper already resolves its real implementation
# lazily via dlsym(RTLD_NEXT, ...) on first real call - by then the app's
# own GL usage has long since loaded libGLESv2.so itself, so no explicit
# link-time dependency is needed at all. <GLES2/gl2.h> is included only for
# its type definitions (GLenum/GLuint/...), not any function linkage.
