"__ANDROID__ is defined by the compiler. It is defined for all Android targets." "ANDROID is set by some build systems, and not in any reliable manner (in AOSP it actually just means that you're in AOSP; it's set even when you're building host code for Windows, so it doesn't mean much of anything)." https://github.com/android/ndk/issues/407 https://github.com/android/ndk/issues/807 Since the toolchain provides __ANDROID__ for actual Android targets, standalone NDK and Soong builds should work. The Mesa CI uses a combination of the NDK toolchain, internal Android stubs and a Debian sysroot when compile testing Android. Long-term, it should be possible to remove ANDROID and use DETECT_OS_ANDROID everywhere.
