=======================
In this article, we briefly describe how to build Android binary using
`Android NDK <https://developer.android.com/ndk/index.html>`_
cross-compiler on Debian Linux.
`Android NDK <https://developer.android.com/ndk>`_ cross-compiler on
Debian Linux.
The easiest way to build android binary is use Dockerfile.android.
See Dockerfile.android for more details. If you cannot use
Dockerfile.android for whatever reason, continue to read the rest of
this article.
We offer ``android-config`` and ``android-make`` scripts to make the
build easier. To make these script work, NDK toolchain must be
installed in the following way. First, let us introduce
``ANDROID_HOME`` environment variable. We need to install toolchain
under ``$ANDROID_HOME/toolchain``. An user can freely choose the path
for ``ANDROID_HOME``. For example, to install toolchain under
``$ANDROID_HOME/toolchain``, do this in the the directory where NDK is
unpacked:
We offer ``android-config`` script to make the build easier. To make
the script work, NDK directory must be set to ``NDK`` environment
variable. NDK directory is the directory where NDK is unpacked:
.. code-block:: text
$ build/tools/make_standalone_toolchain.py \
--arch arm --api 16 --stl gnustl \
--install-dir $ANDROID_HOME/toolchain
The API level (``--api``) is not important here because we don't use
Android specific C/C++ API.
$ unzip android-ndk-$NDK_VERSION-linux.zip
$ cd android-ndk-$NDK_VERSION
$ export NDK=$PWD
The dependent libraries, such as OpenSSL, libev, and c-ares should be
built with the toolchain and installed under
``$ANDROID_HOME/usr/local``. We recommend to build these libraries as
static library to make the deployment easier. libxml2 support is
currently disabled.
built with the same NDK toolchain and installed under
``$NDK/usr/local``. We recommend to build these libraries as static
library to make the deployment easier. libxml2 support is currently
disabled.
Although zlib comes with Android NDK, it seems not to be a part of
public API, so we have to built it for our own. That also provides us
proper .pc file as a bonus.
Before running ``android-config`` and ``android-make``,
``ANDROID_HOME`` environment variable must be set to point to the
correct path. Also add ``$ANDROID_HOME/toolchain/bin`` to ``PATH``:

You need to set ``NGHTTP2`` environment variable to the absolute path
to the source directory of nghttp2.
