1. android.so 路径列表

libbinder.so 路径如下:frameworks/native/libs/binder

2. lib_ndk 参考路径:frameworks/native/libs/binder/ndk/Android.bp

cc_library {
 name: "libbinder_ndk",
 vendor_available: true,
 export_include_dirs: [
 "include_ndk",
 "include_apex",
 ],
 cflags: [
 "-Wall",
 "-Wextra",
 "-Werror",
 ],
 srcs: [
 "ibinder.cpp",
 "ibinder_jni.cpp",
 "parcel.cpp",
 "process.cpp",
 "status.cpp",
 "service_manager.cpp",
 ],
 shared_libs: [
 "libandroid_runtime_lazy",
 "libbase",
 "libbinder",
 "libutils",
 ],
 header_libs: [
 "jni_headers",
 ],
 export_header_lib_headers: [
 "jni_headers",
 ],
 version_script: "libbinder_ndk.map.txt",
 stubs: {
 symbol_file: "libbinder_ndk.map.txt",
 versions: ["29"],
 },
}

从这里可以看出libbinder_ndk.so --依赖于---> libbinder.so 。

3. lib_ndk 对应的samples中的 makefile: iface.h

cc_library_static {
 name: "test_libbinder_ndk_library",
 defaults: ["test_libbinder_ndk_defaults"],
 export_include_dirs: ["include"],
 shared_libs: ["libbinder_ndk"],
 export_shared_lib_headers: ["libbinder_ndk"],
 srcs: ["iface.cpp"],
}

4. 参考 iface.cpp

5. 然后想办法传递parcel对象
