Building with the Android Class Library
---------------------------------------
As an alternative to both the Avian and OpenJDK class libaries, you
can also build with the Android class library on some platforms
(currently Linux works and OS X mostly works). To build this way, do
the following, starting from the Avian directory:
can also build with the Android class library. Now it should work on Linux, OS X and Windows.
cd ..
mkdir -p android/system android/external
cd android
The simpliest way to build Avian with Android classpath is to use `avian-pack` project: https://github.com/bigfatbrowncat/avian-pack
git clone https://android.googlesource.com/platform/bionic
(cd bionic && \
git checkout 84983592ade3ec7d72d082262fb6646849979bfc)
Avian-pack consists of Avian itself with some Android components (such as libcore and icu4c).

Note that we use https://github.com/dicej/android-libcore64 above
instead of the upstream
https://android.googlesource.com/platform/libcore repository, since
the former has patches to provide better support for non-Linux
platforms. We have also forked
https://android.googlesource.com/platform/external/conscrypt as
https://github.com/dicej/android-conscrypt to patch that project as
well.

OpenSSL version.
Finally, we specify specific commit hashes for each repository which
are known to work. Later versions may also work, but have not been
tested.
