Announcing: Android native code repository
Angus Lees
small set of libraries - and frequent duplication of work in porting
various libraries to Android. To try to address those problems I've
been setting up an easy to use cross-build and packaging system for
Android (based heavily on the OpenEmbedded project). It should now be
ready for wider use, and I hope this becomes a centralised repository
for free software libraries for Android.
Announcing the "Android Native Repository" (aka ANR)
http://code.google.com/p/android-native-repository/
There are really 3 interesting pieces here:
- A powerful build system for easily downloading, patching and
building cross-compiled libraries
- A replacement arm-oe-linux-androideabi-gcc cross-compile toolchain
that hopes to "just work" without all the flags that the official NDK
now requires
- A repository of pre-built Android libraries built using the above,
in a form that is easy for end-developers to install and upgrade
Any questions, join anr-...@googlegroups.com and ask. I don't have
SDL imported yet, but it is high on my list. The toolchain is based
on gcc-4.4.4 and does *not* include rtti and exceptions in the
interests of matching the official NDK as closely as possible - I
expect to change that decision though. If there is a particular
library you want to see, or you have some code you want to add to the
repository, mail anr-users and I can talk you through the process.
The amount of work I (and others?) put into this will very much depend
on perceived interest - so success stories, "thanks", etc will also
have a real impact.
It only works on Linux/x86 right now, but I can easily add other Unix
host platforms if someone asks. I have no experience building things
for Windows/Mac so I don't know how hard they will be to support (I
suspect it will be fine using the usual cygwin, etc environments).
There are some preliminary docs on the ANR website, including a
complete example app using freetype. The basic steps to use this are:
1. Download http://android-native-repository.googlecode.com/files/android-2.2-i686-linux-armv5te-linux-androideabi-toolchain-android.tar.bz2
2. untar that into /usr/local/android (sudo tar jxf $file -C /)
3. In each shell that you want to use this run: source
/usr/local/android/arm/environment-setup
4. Use arm-oe-linux-androideabi-gcc, apkbuilder, etc.
... and when you want to install extra libraries (eg: libpng), do this:
1. (be root - or at least someone who can write to /usr/local/android/)
2. source /usr/local/android/arm/environment-setup
3. opkg-target update; opkg-target install libpng-dev
4. Just use arm-oe-linux-androideabi-gcc, #include <png.h> and -lpng as normal
Current libraries available include: ffmpeg, freetype, libpng,
libjpeg, libmad, tremor, gnutls, expat
Some libraries missing at the moment: flac, SDL, X11 ;)
A bunch of the usual Android SDK tools have hard-coded paths that I
haven't fixed yet and they don't work. Tools required to build
packages (aapt, apkbuilder, adb, etc) all work fine - exotic things
like ddms, 'android' and the emulator don't, so you will want to keep
your "normal" copy of the Android SDK for the time being.
Disclaimer: This is entirely unofficial, unsupported by Google and
has no relationship to the official Android NDK/SDK, except that it
uses some files from them and aims to produce compatible output.
Let me know what you think. Followups should probably go to anr-users
rather than android-ndk, unless the reply is strongly related to the
official NDK.

Is this moving forward ?
I'm currently using a Makefile of my own to integrate the NDK in the
source of an existing multi-platform application.
I could use two things from the original ANR announcement :
- the toolchain could replace much of the stuff in my Makefile
- libexpat (present on Android but unsupported, I believe, so I
have to provide my own)
