i have followed the procedure you described to create the so file.
i modified the workspace file and added the last 2 parts so thew workspace became as follows

workspace(name = "org_tensorflow")

http_archive(
name = "io_bazel_rules_closure",
sha256 = "a38539c5b5c358548e75b44141b4ab637bba7c4dc02b46b1f62a96d6433f56ae",

"https://github.com/bazelbuild/rules_closure/archive/dbb96841cc0a5fb2664c37822803b06dab20c7d1.tar.gz", # 2018-04-13
],
)

load("@io_bazel_rules_closure//closure:defs.bzl", "closure_repositories")

closure_repositories()

We must check the bazel version before trying to parse any other BUILD

files, in case the parsing of those build files depends on the bazel

version we require here.

load("//tensorflow:version_check.bzl", "check_bazel_version_at_least")
check_bazel_version_at_least("0.10.0")

load("//tensorflow:workspace.bzl", "tf_workspace")

load("//third_party/android:android_configure.bzl", "android_configure")
android_configure(name="local_config_android")
load("@local_config_android//:android.bzl", "android_workspace")
android_workspace()

Please add all new TensorFlow dependencies in workspace.bzl.
