Build libprotobuf-java-lite only using core Java SDK APIs

libprotobuf-java-lite is now built against core Java APIs which excludes
Android-only APIs (classes under android.* packages) and private APIs.
"core_current" is a pseudo SDK which is a core Java subset of Android
SDK.

However, this lib has been using sun.misc.Unsafe which is a hidden API
and dependency to the class doesn't seem to be able to be cut easily in
the near future. In order to make it possible to build the lib with the
SDK only, a stubs library called libcore_private.stubs is defined to
provide build-time only information on the hidden APIs exclusively to
protobuf.

At runtime, the Unsafe class is provide by the OS and protobuf is linked
to the class loaded there.

Bug: 73204840
Test: m -j libprotobuf-java-lite is successful and does not show any
link-type check warning

Protocol Buffers - Google's data interchange format

Build Status Build status

Overview

Protocol Buffers (a.k.a., protobuf) are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data. You can find protobuf's documentation on the Google Developers site.

This README file contains protobuf installation instructions. To install protobuf, you need to install the protocol compiler (used to compile .proto files) and the protobuf runtime for your chosen programming language.

Protocol Compiler Installation

The protocol compiler is written in C++. If you are using C++, please follow the C++ Installation Instructions to install protoc along with the C++ runtime.

For non-C++ users, the simplest way to install the protocol compiler is to download a pre-built binary from our release page:

https://github.com/google/protobuf/releases

In the downloads section of each release, you can find pre-built binaries in zip packages: protoc-$VERSION-$PLATFORM.zip. It contains the protoc binary as well as a set of standard .proto files distributed along with protobuf.

If you are looking for an old version that is not available in the release page, check out the maven repo here:

http://repo1.maven.org/maven2/com/google/protobuf/protoc/

These pre-built binaries are only provided for released versions. If you want to use the github master version at HEAD, or you need to modify protobuf code, or you are using C++, it's recommended to build your own protoc binary from source.

If you would like to build protoc binary from source, see the C++ Installation Instructions.

Protobuf Runtime Installation

Protobuf supports several different programming languages. For each programming language, you can find instructions in the corresponding source directory about how to install protobuf runtime for that specific language:
