Android’s `Build` and `Build.VERSION` APIs expose platform and firmware metadata, but those values serve different purposes. Use the numeric API level for compatibility checks, treat display strings as diagnostics, and avoid turning hardware fields into tracking identifiers.

This Yocto QA failure is a packaging mismatch: `do_install` placed an artifact under `${D}`, but no output package claimed it. Trace the reported path, package it intentionally or remove it, then inspect the generated package rather than hiding the warning.

The `curl` command is not the libcurl development kit. Current Ubuntu builds normally need `libcurl4-openssl-dev`, which supplies headers and build metadata. Use pkg-config or CMake’s CURL target so transitive link flags and non-default installation paths remain correct.

The OpenSSL command and runtime library are not enough to compile C/C++ code. Ubuntu puts headers, unversioned linker files, and pkg-config metadata in `libssl-dev`. Install it for the correct architecture, then let pkg-config or CMake supply paths instead of hard-coding `/usr/include`.
