调研方向
从 packages/host/src/node/prebuilds/android.ts 和 packages/host/src/node/cli/android.ts 中的 TODOs 开始，然后跟踪 Android 库是如何重命名和安装的。验证重命名后的库及其依赖项的 ELF 元数据；当 SONAME 和 DT_NEEDED 条目引用的文件名在构建后确实存在时，即表示完成。
由索引模型根据 Issue 内容生成。
描述
When we're building for Android we rename the dynamic library files but, we don't update the SONAME which should be updatable by running /toolchains/llvm/prebuilt//bin/llvm-objcopy --set-soname=libnewname.so liboriginal.so
The two TODOs in the tree that track this
Adding permalinks (against 29a527d) since both halves of the renaming problem are marked in the source but only the first was described above.
1. The renamed library's own SONAME — prebuilds/android.ts copies the library to lib<name>.so and leaves its install path pointing at the pre-rename name:
This is what the issue describes — llvm-objcopy --set-soname.
2. The DT_NEEDED entries of libraries that depend on a renamed one — the companion problem, marked separately in cli/android.ts:
Fixing only the SONAME is not enough when one addon links against another: the dependent library's DT_NEEDED still names the original library, so the dynamic linker looks for a file that no longer exists under that name. llvm-objcopy does not rewrite DT_NEEDED; patchelf --replace-needed <old> <new> does, or the entries can be patched directly.
Both are the same underlying cause — we rename files after the linker has already baked the old names into the ELF headers — so they are probably best fixed together.
